ABSTRACT:
A settling tank for dewatering a thin slurry is provided in a lined portable container and with a disposable filtering means. A novel method of processing the slurry by settlement of the solid phase and removal of the liquid phase in cycles avoids the clogging of the filtering means. The settling tank can be easily transported and dumped without requiring the transferring of residue sludge or the cleaning of equipment.
