Abstract
To decrease the H2S and induce effective anaerobic digestion of waste- activated sludge (WAS), the micro-organisms concentration within the s ludge were ruptured by a mechanical jet stream and smashed under a pre ssure of 30 bar. Using this procedure, the H2S concentration was decre ased from 30-50 mg/l of intact WAS to 27-240 mu g/l.
