Title: Process for disposing of or treating sewage sludge
Inventor: HOFFMANN ERICH
IPC: C02F11/13
Filed: 1988-11-25
Abstract: In a known process for dewatering and drying municipal sewage sludge by addition of shredded waste paper, centrifuges, sludge presses or pressing tools are used so that the process is relatively complex. A process is proposed according to the invention for disposing of or treating sewage sludge, which process succeeds without the use of centrifuges, sludge presses or pressing tools but nevertheless ensures an efficient economical drying of sewage sludge and creates a storable end product which is substantially harmless from the hygienic aspect and occupies much less volume than the starting material and causes no odour pollution. In particular, non-thickened sewage sludge is mixed with dust-like or (pre)shredded waste paper having a maximum water content of 5 to 10% in a weight ratio of 35% waste paper and 65% sewage sludge and is allowed to evaporate, or is dried or dewatered, by microbial heating over several days at above 60@C.
