How to fine-tune sludge filter presses

Sludge Aerobic activated sludge can quickly stabilise organic pollutants in wastewater and has good self-coagulation ability and settling performance. The purification effect of aerobic activated sludge is similar to that of coagulant in water treatment engineering. At the same time, it can absorb and decompose the dissolved pollutants in water. Because it is composed of live microorganisms, it can...
