Abstract
Inventia se refera la purificarea biologica a apelor reziduale care contin concentratii mari de etilenglicol. Procedeul consta în introducerea în apele reziduale ce urmeaza sa fie purificate si care contin etilenglicol si microelemente, a surselor de fosfor, de azot si a unui microorganism de special Arhrobacter. Apoi se executa cultivarea microorganismului mentionat la o temperatura cuprinsa între 20 si 35 degree C pâna la purificarea apelor reziduale de etilenglicol. Procedeul mentionat permite ca, dupa metoda biologica, sa se purifice ape reziduale care contin peste 2000 mg/dm3 etilenglicol, pâna la un grad de purificare de 99%.
