BACKGROUND OF THE INVENTION Field of the Invention
The present invention 5 apparatus, methods and systems remove the sediment and suspended solids in the water discharged from the construction, buildings or other sites where the discharge of suspended solids in riparian systems or storm drainage systems is to be avoided and, more particularly , to the separation of sand, oil, biomass, and other remains of the water and the reduction of the amount of nutrients and nitrogen compounds in the treated water. More broadly, the present invention relates to apparatus, methods, and systems for treating high volumes of liquids, mixtures, suspensions, and the like, to separate them into constituent parts; and to process liquids, mixtures, suspensions and the like to remove solids and discharge water with less suspended solids.
Relevant Background
Modern storm drainage systems involve directing storm water to storm or sewer drains, where water is collected for further processing and disposal or is simply discharged into larger water flows. In those systems, stormwater is guided to flow from slopes

Using the force of storm water can example, paper, cans and example, grass, leaves, silt, sand, stone, and streets in gravity storm drains. During that flow, they will collect waste, debris (from cigarette butts), biomass (from excrement and discarded food), oil, contaminants, heavy metals, and discarded medical devices and personal products (eg, used needles and condoms) and other particles. . Additionally, storm drainage systems can collect other runoff water such as water used for irrigation. Rainwater and runoff water can naturally flow through soil or other soils and collect organic matter or chemicals, such as plants, leaves, hydrocarbons, nitrates, or other compounds.
There is a great deal of interest in effectively processing storm water. Drainage systems usually flow into natural water systems, such as oceans, lakes, rivers, streams, and other similar water flows. This would help protect the environment if there was a realistic, cost-effective ability to separate man-made and natural pollutants and wastes before drainage is directed into natural water systems and to avoid excess natural ecological balance of such systems. In addition, if stormwater and other runoff can be treated effectively and

----------, |, | „, There is a potential that recaptured water can help meet domestic water needs.
There is also considerable interest in treating fluids for use in mining, agriculture, and industrial. In addition to water treatment and purification, products separated from the fluid during treatment can be of value. For example, minerals in mining or farm runoffs that contain high nutrient contents, various constituents of lubricants, and the like can be separated, collected, and reused or recycled. In addition, recovery of fluids or solids in industrial and wastewater applications may be of interest.
Construction and building sites frequently collect or produce significant amounts of stormwater runoff, which contains high levels of suspended solids, that needs to be pumped away from the site. River and river drainage systems may be unable to adjust to the discharged fluid, especially the large amount of sediment that can be deposited. In order to protect the environment near such sites, government regulations may require that the water at the sites be pre-processed to reduce the amount of solids
IMP <sup>, NST,</sup>£<sup>T</sup>L?
INDUSTRIAL suspended that are unloaded. Typically, the discharged water is not environmentally hazardous but may contain gravel, dirt, sand, clay, and other suspended solids that need to be removed or reduced in concentration. After removal or reduction of the concentration of suspended solids, the processed water may be suitable for discharge to a nearby water system.
Stormwater and groundwater runoff is typically stored in an on-site pond that can slowly evaporate or soak up in the surrounding soil. Such ponds can flood on roads, in streams, through property, and in areas of low sediment causing flooding and deposition of large amounts of sediment.
The process for removing suspended solids from large volumes of water stored on construction sites and buildings is often called water removal. The usual method of water removal involves the use of a water removal bag. Water removal bags, also known as dirt bags, gravity bag filters, and sediment filter bags are simply, simply large, rectangular filter bags, powered by one or more sources of water that needs treatment. Typically a pump is used to move the water from a water tank
<img file="MX338565B_D0008.tif" />
MEXICAN INSTITUTE OF PROPERTY
INDUSTRIAL
<img file="MX338565B_D0009.tif" />
storage for feeding to the water disposal bag.
The water flows inside the bag and passes through the wall of the bag. The bag wall filters out solids of a particular size. Water is leached through the surface of the bag into the surrounding environment. In essence, water removal bags are large filters that separate suspended solids from water. The bag is filled with solids and can then be discarded.
The appropriate size of a water disposal bag for a particular application is generally determined by the cost of flow and the components in the water that needs to be processed. The amount of solids in the water can affect the size of the required water removal bag because a large large sediment load will more quickly fill a bag and plug the pores in the bag material. Certain solids, similar to clay, will plug water removal bags very quickly.
When estimating the appropriate size of the water disposal bag for a particular application, a selected bag that is too large for the task spends money and takes up valuable space on site, while a bag that is too small for the task will need the use of multiple water disposal bags, a program to inspect and replace those bags, and time,
<img file="MX338565B_D0010.tif" />
M £ XICANH INSTITUTE OF INDUSTRIAL PROPERTY
<img file="MX338565B_D0011.tif" />
effort and cost to actually inspect and replace additional bags.
On the other hand, variations in flow rate and components in the water pumped from the site may require the acquisition of an inventory of the bags to adjust for these variations. If a high flow expense is desired, a larger water removal bag (eg, fifteen feet by fifteen feet) can be deployed, or multiple water removal bags can be fed through a parallel hose manifold, or a water removal tube that can be hundreds of feet long can be deployed. These large bags and tubes are custom made, costly, and due to the weight of the water and the collected sediment will put a large load on the surface. Such loads can be damaging to the ground and other surfaces. The flow of water through the bag (or tube) can also cause erosion in the surrounding area in a pattern that can be difficult to predict.
Another problem with water disposal bags is that they are usually designed to be used only by one

PE INDUSTRIAL PROPERTY to be discarded. Also, a filled bag that sits on the ground will require heavy machinery to move it. This may be impossible to move a partially filled bag without ruining it. Reusable bags have the difficulty of transporting the heavy bag and removing a heavy sediment load from a relatively fragile bag.
The fragility of a water disposal bag presents problems as well. A bag can be punctured or torn at a construction site by the surface on which it is placed or by inadvertent contact with machinery. As they fill, the water removal bags can be stretched to a different position. A bag that is stuffed or exposed to excessive water pressure can explode. At high pressures, a bag explosion could become a dangerous explosion of water and sediment.
Better methods and systems are needed to remove water in large amounts of fluid to remove suspended solids.
United States Patent No. 7,311,818 to Gurfinkel discusses a method of a water separation unit having an interior and exterior housing for collecting rainwater. Rainwater enters the interior housing where they are supposed to be
<img file="MX338565B_D0015.tif" />
separated the water and the remains. A series of hollow tubes connect the inner housing to the outer housing to allow liquid to pass inside and collect in the outer housing and flow out of the unit through a network of discharge tubes. One problem with this procedure is that the tubes can be plugged with debris. Another problem with this procedure is that most of the dirt and sand is not collected at the level of the tube in the inner housing; rather, it flows through the tubes and can be withdrawn into the discharge line and out of the outer housing. Still another problem with this procedure is that the unit must be completely drained before cleaning.

The decontaminant is positioned inside the box between the inlet and the outlet and rises and falls with the water level in the box. Rainwater is directed to pass through the basket to the decontaminant where floating debris is collected. One problem with that procedure is that parts in

INDUSTRIAL

Movement that can be broken or damaged is required for the decontaminant to move. Another problem is that the floating debris remains in contact with the waste water, promoting decomposition of the debris.
United States Patent No. 7,857,966 to Duran discusses a method for a stormwater inlet apparatus having inlet and outlet pipes level with each other, where the wastewater flows directly through a receptacle. The apparatus includes a bell and a skirted shuttle attached to an interior wall of the receptacle on the outlet tube. Waste water flows under the hood and skirted shuttle and out through the outlet. In the process, sediments heavier than water sink to the bottom of the retention, while debris lighter than water floats to the surface of the wastewater in the receiver. One problem with that procedure is that a sealed hood prevents air flow, allowing a siphon to develop and pull the wastewater level down and potentially remove floating debris, thereby reducing the performance of the appliance. Also, the remains remain in contact with the waste water, promoting the decomposition of the remains.

OF INDUSTRIAL PROPERTY rainwater treatment. A sp treatment unit connects to a control chamber through which fluid flows. Fluid is diverted via a control partition to an inlet tube in the treatment unit and returns through an outlet tube. If the fluid flow exceeds the capacity of the inlet tube, excess fluid flows over the control partition at the outlet of the control chamber. One problem with the procedure is that it is not well suited for a retrofit application due to the lack of significant degree between input and output of the control chamber. Another problem with this procedure is that there is no separation between the different types of remains, that is, biomass, hydrocarbons, silt and sand, etc .; each one being mixed in a potentially toxic soup.
United States Patent Publication No.
10 / 430,170 by Peters et al., Discusses a system for removing contaminants from storm water. Rainwater flows through a process chamber that comprises a series of vertical baffles that extend from the top, bottom, and side of the chamber. Rainwater flows through the chamber around the derailleurs, and debris is trapped along the chamber bottom and by filters placed in the spaces between the baffles and chamber. A problem with this procedure
<img file="MX338565B_D0020.tif" />
is that all the filtration is done in the water, in this way, the remains remain in contact with the water that promotes the decomposition of the remains. An additional problem with that procedure is that all debris is collected at the bottom of the chamber, limiting the chamber's ability to collect debris. Another problem with that procedure is that the relatively small gaps between the baffles and the chamber can easily become plugged with debris.
In addition there is a need for an efficient, cost-effective apparatus, method and systems to separate stormwater, operating fluids, lubricants, coolants, wastewater, and the like, to separate solids, hydrocarbons, contaminants, and dirt, and recapture and recycle desired components.
BRIEF DESCRIPTION OF THE INVENTION

An additional goal is to provide a device that is compact, easily installed on a city street with an existing drainage trunk line, and easily installed in a high water area with deep storm water systems.
Still another objective of one embodiment of the invention is to provide a stormwater treatment system capable of diverting water off-line to prevent plugging of a treatment unit in the event of excess flow conditions. An additional goal includes a system that will not reintroduce newly collected contaminants into the storm drainage system. A still further goal is to prevent bacteria, dead rodents and other debris considered to be health hazards from backwashing and resurfacing on roads and other property.

The stormwater treatment unit 100 houses the containment vault 101. Preferably, the dimension of the vault is 1.86 meters (6 ') long x 2.13 (7') wide x 2.53 (8'4) high, and the vault is made of liquid impervious concrete with walls that are 15.24 cm (6) thick. The dimensions of the vault can be adjusted depending on the application and can be made of other suitable materials such as metal or plastic. The interior of the vault defines a chamber 150.
Containment vault 101 has three openings connecting chamber 150: inlet 110, outlet 120, and access opening 105. Inlet 110 is placed on one side of chamber 150 and preferably 30.48 meters (12) in diameter and is fitted with a similarly sized tube 111. The outlet 120 is placed on the opposite side of chamber 150 and is preferably 30.48 meters (12) in diameter and is also fitted with a similarly sized tube 121. Access opening 105, preferably in the form of a manhole, is preferably located at the top of vault 101 and is fitted with a cover. Preferably, the tube materials can be PVC, metal, or other types of materials suitable for use with anticipated fluids and contaminants. Inlet 110, outlet 120, and tubes 111 and 121 may be of other sizes suitable to accommodate different volumes of

fluid and flow expenses.
In a preferred embodiment, inlet 110 is positioned approximately 12.7 cm (5 inches) higher than outlet 120. Inlet 110 and outlet 120 are thus very similar in height, allowing deep installation of the unit in areas with a high water table that cannot support a large difference in height between inlet 110 and outlet 120.
Outlet tube 121 extends through outlet 120 and bends down toward the bottom of the chamber
150 in vault 101. Inlet 122 of tube 121 faces down toward the bottom of chamber 150. Outlet tube 121 is separated from chamber 150 by wall 140. Wall 140 preferably extends from the outlet of up 120 to a position midway between outlet 120 and the bottom of chamber 150 that allows liquid in chamber 150 to flow into tube 121. The height of inlet 122 is at or above the bottom end of the wall 140. Optionally, portions of the outlet tube 121 below the outlet 120 can be drilled to further diffuse the liquid withdrawal by allowing the liquid to enter through the sides of the tube 121.
If the outlet 123 of tube 121 extends less than water level 160 (as is normally expected to allow flow through tube 121), the flow of water in

the height of the inlet 122 of the vent 130 connects and extends upward from the outlet tube 121. The vent tube 130 allows air flow to tube 121 to prevent the creation of a siphon during high volume flows. . Alternatively, tube 121 could be drilled below water level 160 to allow air flow if water level 160 is below the bottom of outlet 120 and reduce or avoid a siphon effect.
A gap exists between the top of the wall 140 and the top of the chamber 150 to allow air flow near the vent tube 130 and to avoid the siphoning effect. Wall 140 further serves as a physical barrier to protect tube 121 from inlet water pressure and debris flowing from inlet tube 111. Wall 140 is preferably made of stainless steel, plastic, or other material suitable for use with anticipated fluids and contaminants.
Wire mesh 171 is located below inlet tube 111 and is preferably above the lowest part of outlet 120. Due to pressure equalization, the water level 160 should normally be in the range of the outermost part. low from outlet 120, such as a higher water level that could cause outflow from the outlet tube <sup>27</sup> ¡NstÍtotÓmbíicako Y <^ TSí ^ * «! 2 ei ia rsc« í £> Ao

121. Wire mesh 171 is preferably located above water line 160 and separates large debris from the stormwater inlet stream. Wire mesh 171 is preferably a metal mesh or wire mesh with holes properly sized to collect debris from the inlet fluid on top of the wire mesh while allowing smaller debris, particles, and fluids to flow through it. Wire mesh 171 collects leaves and other large piles of biomass above water level and prevents collected debris from soaking in liquid in chamber 150 or floating at water level 160. By keeping biomass on the mesh of wire 171 out of the accumulation of water, the decomposition process for that biomass is slowed down and the leaching of ammonium nitrate, other nitrates, and other components of organic matter is reduced. By keeping trash and other larger debris on 171 mesh wire out of the water buildup, leaching of chemicals, contaminants, and debris into the water is reduced.
In the preferred mode of operation of the storm water treatment unit 100, the inlet water flows into chamber 150 from inlet tube 111 from the side, flows into the water accumulation in chamber 150, and flows out of the chamber 150 through outlet tube 121. From

Preferably, chamber 150 is pre-filled with water at a level above inlet 122. Inlet water, which could be stormwater, runoff, or other sources, contains varying degrees of debris, biomass, and other solid, semi-solid, and particulates. These materials include elements heavier than water, such as sand and metals, and elements lighter than water, such as plastics, grease, oils, and other hydrocarbons. The rainwater treatment unit 100 works by separating the elements in the contaminated water by density. As the inlet water flows through the wire mesh 171, the heavier elements settle as sediment at the bottom of chamber 150; lighter elements float on top of water line 160 as floating debris 165.
If oil, or another petroleum product, is introduced into the unit as part of floating debris 165, the oil acts as a cover that reduces, if not eliminates, the flow of air (eg, oxygen) in the fluid collected in the unit and, in this way, retards the growth of bacteria, algae, and the like in the collected fluid. Reducing such growth of microorganisms lengthens the unit's maintenance cycle and reduces a health hazard for maintenance workers and the environment.

In maintenance, the stormwater treatment unit 100 is periodically cleaned depending on the capacity of the unit, the volume of stormwater processed, and the levels of contamination. Dried leaves, other biomass, and trash can be collected from wire mesh 171. Floating debris 165, such as oil and grease, can be removed from the surface at water level 160. The collected sediment can be vacuumized or otherwise removed from the bottom of chamber 150. Optionally, a vacuum can be used to collect other portions of liquid in chamber 150. As such, the open, modular design of unit 100 keeps the unit accessible for easy maintenance and cleaning.
Referring to Fig. 1A, in one embodiment of the invention, the outlet tube 121 is preferably a collector comprising two or more tubes extending downward in chamber 150. The collector tubes are

150 from the removal in tube 121 and into the uniform pattern of the collected sediment as compared to the use of an individual centrally located outlet tube inlet . In another embodiment of the invention, a single centrally located outlet tube inlet is used.
In another embodiment of the invention, a baffle (not shown) is located below inlet tube 111 and above wire mesh 171. Incoming storm water is drained into the baffle and dispersed. The baffle helps to slow the emptying of the inlet water out of tube 111 and prevents the inlet water from taking a deep plug that would push materials through wire mesh 171 and cause great turbulence that would interrupt sediment settlement in the bottom of chamber 150. In another embodiment of the invention, the baffle may be a spreader board that diverts the water flow and disperses the water across the length and width of the chamber.

IMPI manifolds 172 and 173 are located below the 1717 wire mesh. The manifolds 172 and 173 are preferably made of stainless steel, and are shaped with grooves to present a sawtooth cross section to retard waste of inlet water in chamber 150 and help sediment the collection. Collectors 172 and 173 increase surface area contact with inlet water and can be angled, textured, coated, magnetized, or use other cross-sectional conformations, to collect certain materials. In a preferred embodiment, the grooves in manifold 172 are 10.16 cm (four inches) deep and the grooves in manifolds 173 are 0.3048 meters (twelve inches) deep. Alternatively, the collectors
172 and 173 may include a projection pattern that induces turbulence to collect certain materials as used in mining operations. Collectors 172 and 173 could also be magnetized to collect certain metals. In a further embodiment of the invention (not shown), manifolds 173 are positioned above water line 160. In a further embodiment of the invention, multiple levels of collectors 172 and 173 are used for cascaded inlet water. The height of collectors 172 and 173 can be adjustable.
Optionally, collector 155 is located at the bottom

Collector 155 is also preferably made of stainless steel and formed with flutes to create a cross section of saw teeth. Manifold 155 has increased surface area contact with the flowing fluid and may be angled, textured, coated, magnetized, or use other cross-sectional conformations to collect certain materials from the fluid. The grooves in the collector 155 are preferably 5.08 cm (two inches) deep.
Also optionally, filler blocks 158 are placed in the bottom corners of chamber 150. Filler blocks 158 form the bottom of chamber 150 to help reduce turbulence in the water flow and further aid in collection efficiency sediment and increase the distance between the sediment collected at the bottom of chamber 150 and inlet 122.
In a further embodiment of the invention, the position or dimensions of wall 140 are adjustable to adjust the flow of water to inlet 122 and to adjust the efficiency of the treatment process or to extract water from different levels within chamber 150 - is that is, closer to water level 160 against closer to the bottom of chamber 150.

Stormwater treatment system 200 can be constructed to modify an existing trunk drain line with the entrance of trunk line 201 and the exit of trunk line 202. In an exemplary embodiment, drain flow chambers 280 and 290 and the rainwater treatment unit 27 0 are added to the existing trunk line. The side view of the system shown in Figure 2B does not show the existing trunk line for simplified illustration. System 200 has the advantage of off-trunk operation that runs parallel to the existing drain trunk.
Camera 280 includes a baffle 281 that
<img file="MX338565B_D0044.tif" />
it comprises a wall at a short angle to divert the flow from the inlet 201 to the connecting tube 271. The connecting tube 271 connects the chamber 280 with the treatment unit 270. The connecting tube 272 connects the treatment unit 270 with the chamber 290. Conventional backlash prevention 291 is preferably provided at or near the junction of tube 272 and chamber 290. Treatment unit 270 may have a conventional design or a design in accordance with the present invention (as shown).
In system 200 operation, inlet water from trunk line inlet 201 is diverted via baffle 281 in tube 271 and in stormwater treatment unit 270. The water is treated in unit 270 and it returns to chamber 290 via tube 272. The treated water flows from chamber 290 to trunk line outlet 202. Backflow prevention 291 reduces or prevents the return of the outlet water to the stormwater treatment unit 270 via the outlet tube 272.
In a preferred embodiment of the invention, chambers 280 and 290 are lined with manifolds 282 and 292, respectively, at the bottom of the chambers. Manifolds 282 and 292, similar to manifolds 172, 173, and 155 in Figure 1, are preferably made of stainless steel and formed with flutes to present a section

Manifolds 282 and 292 preferably align with the sawtooth cross section perpendicular to the water flow, for example, collinear with tube 271 for manifold 282 and with tube 202 for manifold 290, to maximize collection of the sediment. Collectors 282 and 292 can also be textured, coated, or magnetized, or use other cross-sectional shapes to collect certain materials. The grooves in manifolds 282 and 292 are preferably two inches deep.
Figure 3 illustrates an inlet drain flow chamber for a stormwater treatment system in accordance with one embodiment of the invention.
Drain flow chamber 380 connects to inlet 301 from an existing drain trunk line, outlet 303 to an existing drain pipe, and tube 371 to a stormwater treatment unit 370. Baffle 381 on the Chamber 380 diverts the ordinary flow of inlet water from inlet 301 to tube 371 for water treatment. An excess flow of inlet water passes over baffle 381 to outlet 303. Baffle 381 is preferably constructed of concrete or 15.24 cm (6) concrete blocks, but may be constructed of other suitable materials with other dimensions. In a modality

INDUST BAD preferred, baffle 381 extends to a height no higher than the top of tube 371 and manifold 381 is positioned at the bottom of chamber 380.
In operation, as inlet water enters drain flow chamber 380 from inlet 301, water is blocked from outlet 303 by baffle 381 and diverted to tube 371 in a water treatment unit pluvial 370 for treatment. If an initial surplus flow condition accumulating in stormwater treatment unit 370 causing the water level in tube 371 to rise to the top of the tube, the water level in chamber 380 rises to the top. top of baffle 381 and excess inlet water flows over top of baffle 381 at outlet 303 of the trunk drain line. Effectively, chamber 380 with baffle 381 acts as an overflow prevention system for unit 370. Prevention of surplus flow in stormwater treatment unit 370 is an important aspect of the system because a surplus flow condition can cause debris, sediment, contaminants, soils and the like collected by the unit to be flooded from the unit and back to the drainage system reducing, or completely negating the performance of the unit. Alternatively, in cases where an unexpected volume of stormwater flows through inlet 301

If an excess flow condition occurs in chamber 480A, excess inlet water flows excessively to baffle 481A into tube 403 and enters flow drain chamber 480B. Baffle 481B diverts inlet water into 470B water treatment unit. If an overflow condition occurs in chamber 480B, excess inlet water flows excessively from baffle 481B to tube 404.
The treated water flows out of units 470A and 470B into tube 472, through backstop prevention 491 and into chamber 490, includes manifold 492 at the bottom of chamber 490. In an exemplary embodiment of the invention, tube 472 is 45.72 cm (18) in diameter. Backflow prevention 491 is a conventional backflow prevention to reduce or prevent water from flowing from chamber 490 to tube 472. Optionally, the outputs of the 470A and 470B units can also be equipped with backstop prevention units.
While system 400 contains only two stormwater treatment units arranged in parallel, additional units can be added and fix the configuration of the 470B unit.

A portable water treatment system · (PWT) 660 according to an embodiment of the invention seems to benefit from a combination of principles related to the interaction of particles and liquids in water. The first principle relates to the density of water versus the density of polluting particles and polluting liquids. Particles and liquids that have a density greater than that of water will tend to settle, and particles and liquids that have a lower density will tend to float. The second principle is that particles tend to settle faster in still water than in fast-moving or turbulent water. The third principle is that the more particles will tend to settle out of solution the longer the sedimentation is allowed. The fourth principle is that particles tend to sediment more when they impact a solid surface. The PWT 660 system described above is configured to maximize the amount of solids

Due to the size of the trailer and the weight of the water during operation of the PWT system, the trailer has 680 stabilizers or levelers at each corner of the trailer to reduce weight on the tires and axles of the trailer and to level (or intentionally angular) the trailer top surface and PWT system. Inlet holes 830, outlet holes 960, and drain holes 685 are also shown.
Alternatively, the 660 system can be built on or as part of a van, truck, truck trailer, tractor-trailer truck, or other suitable motor vehicle. The PWT 660 system is preferably constructed of metal, such as stainless steel and brass, and, alternatively, may be constructed of concrete, plastic, fiberglass, wood, or any other rigid material suitable for the purpose, or combinations of any of those materials.
One or more drain holes 685 connect to one or more settling units within the 660 system to allow drainage of the units. The front of the PWT 660 system has four 685 drain holes, while the back has two drain holes
685 (only one shown).

Front wall 690, rear wall 700, left wall 710, right wall 720, and bottom 730 can be flat, rounded, or textured. Alternatively, system 660 can be configured as a cylinder, a spherical shape, an irregular hexahedron, or the like, or as a variation between such shapes. The interior of the PWT 660 system is preferably configured as a plurality of separate settling units that are similarly constructed. Alternatively, the sedimentation units can be of different shapes and sizes and not symmetrical.
As shown in Figure 10, the PWT 660 system has a central divider 740 to form two rows of three connected sedimentation units. In each row, two partitions 750 and 760 parallel to front wall 690 and rear wall 700 separate the three settling units. Those parallel partitions form the respective rear or front walls of neighboring sedimentation units. The PWT system shown includes six sedimentation units 770, 780, 790, 800, 810, and 820. Each row of sedimentation units preferably operates independently of the other rows of sedimentation units.

The 680 Stabilizers / Levelers (not in Figure 9) are used to level the PWT 660 system for maximum functionality to allow fluid to flow through the system.

Fluid flows under debris wall 840 to outlet pipes 930 and through the second set of settling units 790 and 800. , respectively. Fluid flows under debris wall 841 to outlet tubes 950 and through the third set of settling units 810 and 820, respectively. Fluid flows under debris wall 842 to outlet 960 for system discharge. Debris walls 840 and 841 block floating debris from reaching the following respective sedimentation units. Debris wall 842 blocks floating debris from reaching Exit 960.
The PWT 660 system is shown with six settling units arranged in two rows of three settling units each for illustrative purposes and simplicity of description of aspects of the invention. However, a PWT system is not limited to such an arrangement.
One or more rows of one or more settling units can be used depending on the requirements of the specific task.
For example, if the task involves treating a

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY large volume of water with a very low suspended solids load, so the PWT system could include many rows of units with multiple units per series. The arrangement will allow multiple water pumps to be used at the same time, while the pumping distance and the time to remove the suspended solids remains largely the same.
As another example, if the task involves treating a water source with a heavy suspended solids load of flocculent solids, the number of units in a row can be increased so that the fluid is depleted longer in the system to allow the solids settle. Alternatively, the PWT system can incorporate a larger number of settling units and multiple rows of units can be connected together in series. For example, a series of flat bed trailers or tractor-trailer trucks carrying multiple settling units could be connected together. The PWT system is easily scaled to larger sizes. The size of each unit, the number of units in a row, and the number of rows of units are not limited and can be any quantity needed for a particular task.

The row of sedimentation units on the right shown in Figure 9 will be described to illustrate the water treatment in connection with Figure 10. The row on the left is structured and functions accordingly. In an alternate mode, the left and right rows include settling units of different sizes, in different numbers, or differently configured.
Figure 10 shows three sedimentation units 10 770, 790, and 810 of similar construction. Each settling unit includes two sections separated by a respective debris wall 840, 841, and 842. The first section contains the horizontal manifolds 890, 910, and 920 and comprises the longest length of the settling unit. The
<img file="MX338565B_D0059.tif" />
<img file="MX338565B_D0060.tif" />
Second section is shorter in length and contains no collectors. Remain walls 840, 841, and 842 serve as partial barriers to divide sedimentation units into two sections in fluid communication. Example fluid levels are shown in units 770, 790, and 810 to aid in understanding the invention.
The 890, 910, and 920 horizontal manifolds can be of any shape, size, or surface configuration. The collector surfaces can be flat, undulating, approximating or the like. In the cross section the collector may approximate a ceno wave, square wave, or triangle wave, or be angled on one side, inclined towards the flow of water, or form an open box with depth or the like. The plurality of collectors can be arranged in a cascade pyramid with the uppermost collector having the smallest width or length dimensions of the collectors in the settling unit with each successive collector increasing in width or length dimension. , until the bottom of the collector has the largest width or length dimensions. Alternatively, the collectors in a sedimentation unit can be arranged in an X arrangement or zigzag configuration with each collector overlapping the collector below it so that there is no direct vertical path for water flow from the water surface to the

Debris walls 840, 841 and 842 preferably connect to the left, right and sides of the respective sedimentation unit in which each is contained. The upper edges of the walls 840, 841 and 842 are higher than the water outlet of their respective units, so that the surface of the water in the sedimentation unit is below the upper edge, and higher than the upper surface of the upper collector 890. Large particles or other floating materials stop by these walls of the passageway at the unit outlet. Floating material will accumulate against the wall and will remain in the first section of the unit. The top edges of walls 840, 841 and 842 are shown in Figure 10 at different distances from the tops of the respective sedimentation units. Alternatively, those top edges may be at the same distance from the tops of the respective sedimentation units or at other different distances.
The bottom edges of walls 840, 841, and 842 extend toward, but remain above, the bottom of the respective settling unit to allow water flow from the first section into the respective second section as it passes below the edge of background. The bottom edge of each of the walls that are preferably in

In sedimentation units 770 and 790, a circular tube arrangement 621 (shown in Figure 7) hangs in the water collected in the second section of the respective unit. The top of the circular tube includes two vertical tubes 630 that extend above the surface of the water and are open to the air. This prevents the creation of a siphon effect within the 621 circular tube arrangement that draws water (and sediment) out of any unit. At the bottom of the circular tube arrangement 621 is a cutout 625 to allow water to enter. The water from this cutout 625 goes up to either side of the circular tube arrangement 621 to enter the next settling unit through the discharge tube 623.
As shown in Figure 10, for settling unit 770, discharge tube 623 in tube arrangement 621 is connected to outlet tube 930. For settling unit 790, discharge tube 623 is connected to tube outlet 950. For settling unit 810, shelves 940 extend between the barrier and the rear wall to interrupt the flow of water. Shelves define a winding route to exit 960 to prevent settlement of suspended solids, as shown in
IMPI

Alternatively, the 940 shelves could be replaced with a 621 circular tube arrangement as in the 770 and 790 units, the 621 tube arrangements in the 770 and / or 790 units could be replaced with the 940 shelves. As alternatives Additionally, a combination of circular, downward tube arrangements extending from vented tubes, and / or shelves could be implemented in the second section of one or more of the 770, 790, and 810 units.
As shown in Figure 10, it is preferable for the collectors, debris wall, and outlet pipe for each unit that is lower relative to its predecessor unit to allow natural water flow through the system due to the gravity and water level equalization on both sides of the debris wall in the unit.
In general, inlet water flows through inlet 830, through unit 770 around manifolds 890, 910 and 920 and under wall 840 to the outlet tube arrangement and through outlet tube 930 to the unit 7 90. Correspondingly, inlet water from unit 770 flows through unit 790 to unit 810. Inlet water from unit 810 flows through outlet 950, through unit 810 around manifolds 890, 910, and 920 and under wall 840, around shelves 940, and through outlet 960. Tubes

More specifically, untreated water enters the PWT 660 system through inlet 830 in front of the first settling unit 770. At the inlet to settling unit 770, untreated water preferably impacts the baffle shield. 850 causing the water flow to disperse and slow down. Deflector shield 850 is preferably made of metal and is configured to divert water flow through most of upper collector 890. Optionally, the deflector shield 850 is omitted.
After the inlet water impacts the upper collector 890, its velocity decreases and its direction changes. The water cascades down from the upper collector 890 to the middle collectors 910 and then the lower collector 920. When the sedimentation unit is filled with fluid at the outlet pipe level 930, the untreated inlet water flows into the accumulation of water collected and around the plurality of collectors along the same route. Preferably, the sediment from the inlet water is collected in each of the collectors 890, 910 and 920 and at the bottom 730 of the 770 unit. The water with less sediment than the inlet water passes under the wall 840 to the arrangement of circular tube and leaves the unit by the
<img file="MX338565B_D0065.tif" />
exit 930.
The inlet water flow in the 790 unit follows the same path as described for the 790 unit.
In the 810 unit, the water flow is slightly different. Water passing through outlet 950 preferably impacts deflector shield 850 causing the water flow to disperse and slow down. Optionally, deflector shield 850 is omitted.
After the inlet water hits the upper collector 890, its speed decreases and its direction changes. The water cascades down from the upper collector 890 to the middle collectors 910 and then to the lower collector 920. When the sedimentation unit is filled with fluid at the level of the outlet tube 960, the untreated inlet water flows into the accumulation of water collected and around the plurality of collectors along the same route. Preferably, the sediment from the inlet water is collected in each of the collectors 890, 910, and 920 and at the bottom 730 of the 810 unit. The water with less sediment than the inlet water passes under the wall 842, around one or more 940 shelves, and leave the unit via exit 960.
After the water has passed through the three settling units, it exits through outlet 960. The water in outlet 960 contains less solids

than the original inlet water and may be suitable for discharge into a storm drainage system, riparian system, or other water flow. The suspended solids treatment system can have many different configurations depending on the amount of water being treated, the amount of sediment in the water, and the quality of the water required at the end of the treatment.
As shown in Figure 11, the PWT 660 system preferably includes removable covers 970, 971, and 972. Each cover includes handles or 973 lifting points. Covers 970, 971, and 972 are sized to cover the pairs. of units 770 and 780, 790 and 800, and 810 and 820, respectively. The covers reduce the potential for contamination carried by the intake air to the system and allow access to clean the units. Additionally, the covers add structural support to the 660 system during transportation.

Water spills over the edges, left and right of upper collector 890 to flow into the middle left and right collectors 910. These collectors collect slightly less dense suspended solids and any denser sediment that could spill from the upper collector.
Water flows over the middle part collectors 910 and then down to the bottom collector 920 located below and generally between the middle part collectors. After the water flows into the lower collector
920, this can flow either to the left or right over the bottom manifold at the bottom of the settling unit.
The number of collectors in a sedimentation unit can be increased or decreased as appropriate for the specific task.
Figure 14 shows an optional speed reduction shield 850 that can be oriented at an angle 851 relative to the upper manifold 890. Shield 850 is preferably arranged to reduce the speed and force of incoming water from an inlet tube, such as like the entrance

INDUSTRIAL preference to disperse inlet water over a larger area of the 890 upper collector and reduce the amount of sediment that is flushed out of the 890 collector. By slowing down and redirecting the inlet water, it will impact the 890 collector with less force.
Optionally, the 930, 950, and / or 960 outlet tubes can include a weir to collect additional particles. As shown in Figures 16A and 16B and explained with reference to outlet tube 930, outlet tube 930 may comprise a tube of original diameter.
931 and a larger diameter tube 932 with a weir 935. Preferably, weir 935 is comprised of metal wire or other robust particle collecting structure. The increase in diameter between tubes 931 and
932 reduces the flow restriction caused by the landfill.
It is desirable to size the PWT 660 system and its components to allow enough water to flow to prevent fluid from returning to any unit to cause excessive flow. Tubes 830, 930, 950, and 960 are preferably sized to allow water to flow at substantially equivalent expenses. For example, in a preferred embodiment, all four tubes 830, 930, 950, and 960 are 7.62 cm (three inches) in diameter. In another embodiment, tubes 830 and 960 are 7.62 cm (3 inches) in diameter while tubes 950 and 960 are 10.16 cm (4

MEXICAN INSTITUTE inches) in diameter and includes landfills. The flow rate of water with suspended solids in a row of settling units can be up to 50 gallons / minute, preferably up to 100 gallons / minute, and more preferably up to 150 gallons / minute. Even larger configurations of the present invention could adjust flow rates to above 150 gallons / minute.
Each collector has a preferably undulating surface to increase the surface area for sedimentation, produce dead zones of reduced water movement, and separate sediment from flowing water. Figures 17A, 17B, 17C, 18A, 18B, 18C, 19A, 19B, 19C show the manifolds with a sawtooth surface configuration for illustration purposes. Other conformations and cross-section conformations can be used, including more random patterns. Additionally, the ripples can be parallel, perpendicular, or arched to the water flow. The collectors in each settling unit are preferably removable for cleaning.
In Figures 17A, 17B and 17C the upper collector 890 has flanges 1130 and 1140 along the front and rear top edges, respectively, and a rippling surface 900A. Tab 1130 stops the flow of water between the front edge of the collector and the wall

Preferably, the water should flow into the upper collector and then cascade down the left and right edges of the collector so that the middle part collectors 910 impact below them. The front flange 1130 has a cutout of 1135 to fit the inlet tube 830. Along the bottom of the upper collector 890 at the edges, front and rear are edges 1150 and 1160 for contact with or connection to the front wall and respective rest of the unit.
Within the depth produced by the sides and bottom of the collector 890 is an undulating surface 900A. The depth of the collector and the number of ripples within the collector are not limited, and are simply a design choice for a particular task. 1160 handles or attachment points are optionally provided to facilitate removal of the manifold from a settling unit during cleaning.
In Figures 18A, 18B and 18C the middle part collector 910 has an undulating surface 900B between two opposite front and rear walls. Along the bottom of the middle part collector 910 at the front and rear edges are flanges 1170 for contact with or connection to the front walls and respective debris of the

1200 joint are optionally provided to facilitate removal of the collector from a settling unit during cleaning.
As shown in the Figures, it is preferred that the number of undulations on surfaces 900A, 900B, and 900C progressively decrease while the depth of the undulations increases progressively. The collectors are shown with increased depth of undulations from top to bottom as arranged in a settling unit. Alternatively, the size, shape, and depth of the corrugations could be reversed in order to, or otherwise vary between, the upper manifolds, the lower middle portion, or within each manifold itself. A larger or smaller number of collector levels could be used in the sedimentation unit allowing the unit to be shorter or higher if desired as well.
Examples of use of a PWT system according to an embodiment of the invention will be discussed.
Example 1
An active construction site is impacted by heavy rainwater that produces a runoff with 22,000 mg / 1 of suspended solids. A treatment system with three settling units with internal dimensions of 1.5 m by 1.5 m by 1 m each is used to treat the water that
<img file="MX338565B_D0072.tif" />
it is collected at the construction site. The treatment system is considered complete when the capacity of the first settling unit is half solid, the second settling unit is half solid, and the third settling unit is one-quarter solid. The capacity of each sedimentation unit of such class is approximately 1.6 m<sup>3</sup>so that the capacity of the system before needing cleaning is approximately 2 m<sup>3</sup>.
A flow rate of 225 1 / min from the construction site will result in the system needing cleaning after 11 hours of continuous use.
Example 2
An active construction site is impacted by rainwater that produces a runoff with 2,000 mg / 1 of suspended solids. The treatment system in Example 1 would need cleaning after 127 hours of continuous use.
Although the invention has been described and illustrated with a certain degree of particularity, it is understood that the present description has been made solely by way of example, and that numerous changes in the combination and arrangement of parts can be reclassified by those skilled in the art without departing from the spirit and scope of the invention, as is immediately claimed herein.
