Process for potable water purification from nitrites

The invention relates to the water treatment, particularly to the reduction of nitrite-ions content into the potable water.Summary of the invention consists in the fact that a process for nitrite-ion content reduction in the potable water is proposed, including reductant water treatment. Sodium dihydroxyfumarate (DHFNa) is used as a reducing agent in the following concentration ratio:[DHFNa] : [NO2-] =1×10-3... 1×10-4the water purification being carried out during 10-30 min.The technical result of the inventio consists in reducing the nitrite-ions and formation of some nontoxic compounds.
