Abstract

Invenţia se referă la un procedeu de tratare a apelor reziduale. Procedeul conform invenţiei constă în aceea că ionii fosfaţi solubilizaţi sunt convertiţi în fosfaţi insolubili prin atomizarea apelor reziduale în condiţii atmosferice, astfel alese, încât să se obţină transformarea de fază, practic completă, în cristale de gheaţă sau vapori de apă, cu eliberarea dioxidului de carbon şi amoniacului din apa reziduală, rezultând o creştere a pH-ului, care produce conversia ionilor de amoniu la amoniac gazos, o reducere a concentraţiei de ioni fosfat, care se combină cu cationii alcalini de tip calciu şi magneziu şi precipită sub forma unor săruri insolubile.
