Abstract

Straining tanks, used for dewatering industrial or urban waste or sewage sludge, comprise skips with sloping sides, lined throughout with wire mesh grilling supported so as to leave space for drainage to bottom outlets, from surface of settling sludge. The skips are directly transportable, by skip-lorries, to dumping or disposal sites, thus obviating manual transfer from tank to transport. The installation is economical of site space so that it may be located at sludge source, when appropriate.
