<p>Purificn. of effluent, and treatment of the produced sludge, by thickening and dewatering and subsequent biological decompsn. in an aerating reactor. The biological material in the sludge for its biological decompsn. is formed and maintained alive up to the entrance of the sludge into the aerating reactor, while the oxygen required is supplied to the sludge during transport to the aerating reactor in the form of a gas or gas mixt. Sludge disposal problems are eliminated.</p> |
