Title: Sludge processing - uses partial water recirculation to reduce consumption where water supplies are restricted
Inventor: THIELE HEINRICH DR
IPC: C02F11/123
Filed: 1992-06-15
Abstract: To process sludge, the raw sludge is given an initial water extraction action, such as in a mesh belt press, and the extracted water is treated conventionally for use as fresh water as if it were heavily soiled surface water. The water extracted during the thermal/chemical treatment of the raw thickened sludge is replaced wholly or partially by the cleaned water from the pptn. stage to remove heavy metals. The returned sludge water is passed to the mixer to heat the sludge and raise the acidity to maintain a constant pH value according to the supply situation of fresh acid or fresh water. USE/ADVANTAGE - The method is for the processing of sludge where the initial water extraction uses heat from the drying at a decontamination stage together with tartaric acid or other organic acids at 70-75 deg.C. The technique is partic. suitable for areas of water shortages, to convert the sludge into fertiliser and other recycled applications, with min. water and acid consumption.
