Abstract

Invenţia se referă la tratarea apei, în special la micşorarea conţinutului de nitriţi în apa potabilă.Esenţa invenţiei constă în faptul că apa potabilă se tratează cu un reducător pentru ionul nitrit. În calitate de reducător seutilizează dihidroxifumaratul de natriu (DHFNa) în următorul raport de concentraţii:[DHFNa] : [NO2-] = 10purificarea apei efectuându-se timp de 10…30 min.Rezultatul tehnic al invenţiei constă în reducerea ionilor de nitriţi şi formarea unor produşi inofensivi.
