Abstract

A method for the recovery and stabilization of fat, fatty substances, proteins, protein substances and deterioration products of said substances from effluents containing said substances, by treatment with a hydrolyzing acidic metal salt and by precipitation with a base, characterized because the acid hydrolyzing metal salt is added in a sufficient quantity to bind the organic substances present in a complex, because in addition mineral acid is added at the same time or after said addition, if necessary, to reduce the pH to 5 or below this value, after which the complex formed precipitates by raising the pH to 6 or more, by addition of a base and prior, simultaneous or subsequent addition of alkaline-earth ions.
