1. As a mature dewatering equipment, the automatic water washing filter press is widely used in the field of environmental protection and has become an important equipment for sewage sludge treatment.
2. The mechanical dewatering of sludge is mainly to remove the capillary water between the sludge particles. The water content of the sludge after ordinary mechanical dewatering is usually 65% -80%, which is in the form of mud cake.
3. In the past, mechanical dewatering equipment mainly included belt-type automatic water-washing filter press, plate and frame automatic water-washing filter press and decanter settling centrifuge, and now commonly used box-type automatic water-washing filter press and vertical hydraulic automatic water-washing press Filter machine, diaphragm machine and high-pressure plate and frame machine.
4. When sludge is used for landfilling, sludge dewatering can greatly reduce sludge accumulation sites and save costs during transportation; when composting sludge, sludge dewatering can ensure smooth composting (in the process of composting) Generally, sludge has a lower water content); if sludge incineration and centralized treatment are carried out, the high sludge dewatering rate can greatly reduce heat energy consumption and reduce the cost of hazardous materials treatment.
