Abstract
Conform inventiei, procedeul de recuperare a sarurilor anorganice din apele reziduale, consta în aceea ca, apele reziduale cu continut de sulfati, cloruri, fosfati, azotati de sodiu, de potasiu, de amoniu se trateaza cu solventi organici, ca atare sau cu amestecul lor, solventi alesi dintre alcool metilic, alcool etilic, acetona si eter etilic, în raport în volum de 0...100:0...100:0...50, raportul între apa reziduala si solvent sau amestecul acestora fiind de 1:1...1:5 în volum, sarea precipitata se decanteaza si se filtreaza, apoi se trateaza filtratul cu hidroxid de metal alcalin, cînd se separa sarurile anorganice insolubile, iar solventul se recupereaza prin distilare sau antrenare cu abur.
