Dewatering decanter centrifuge, belt pressure filter is the 2 most normal equipment used for waste water treatment and sewage treatment. Below are some features of the 2treatment machines, to tell the different of them, and may help clients make decision.
Chemical consumption of Dewatering decanter centrifuge and belt pressure filter
Dewatering decanter centrifuge, as its centrifugal force is huge, it can remove ultra fine particles from sewage or waste water. The chemical enhancing rate is around 1.2kg/tds,the recovery rate of sewage is around 95%. Water content in the mud cake after dewatering is 65％～80％.
Belt pressure filter in order to improve treating capacity, the filter belt cannot be too much fine. To prevent ultra fine slurry passing the filter belt, more flocculent should be enhanced to get bigger size floc. The chemical enhancing rate is around 3kg/tds, the recovery rate of sewage is around 95%. water content in the mud cake after dewatering is around 80ï¼….
Compared with belt pressure filter, Decanter centrifuge utilize less chemicals. And in some applications, dewater centrifuge can get a good separation performance without adding in any chemicals. Belt pressure filter has to add chemicals for all materials.
Electric consumption and water consumption of Dewatering decanter centrifuge and belt pressure filter
Dewatering centrifuge has a higher electric consumption compared with pressure belt filter. But dewatering centrifuge does not need water for flushing during running. It only need to flush the inside bowl and propeller before stop running. Dewater centrifuge does not need much water for flush. Pressure belt filter should flush the whole filter belt for many times. The water for flush will come back to the system for recycling. It increases the handling load of the system.
Man power cost of dewatering centrifuge and pressure belt filter
Dewatering centrifuge is easy for operation. Especially from some leading suppliers, like GN Solids Control, there are PLC smart control for dewatering centrifuge. 1 operator can control 2 ~ 3 sets dewater centrifuge at the same time.
Pressure belt filter is complex for operation. It requests 1~2 operators for 1~2 pressure belt filter.
Based on above features, and the cost of each machine, clients can choose the suitable separation machine per his jobsite condition.

There are many highlights regarding the equipment: the bowl materials is made from duplex stainless steel 2205 which is made by centrifugal sending your line, and it’s much better than metal 304 and stainless steel 316. The solid waste launch port is protected through special ceramic inserts that is certainly made by world famous manufacturer along with longer and more endurable lifetime. The adjustable effluent dock make the pond depth adjusting easier and more convenient and also fast. The pneumatic operated spring will make the beginning of the cover more easily and also safely. During the transportation, typically the bowl lifting bracket are able to do as the protection for the bearings. The bearings are made from the world famous SKF company. Both motors are placed at a single side of the equipment and prepare it smaller footprint. The actual conveyor surface is made from Tungsten carbide tiles which is much more endurable and easy for servicing. The VFD system is usually provided by ABB or SIEMENS. ATEX and IEC EX LOVER for zone 1 control panel can be provide seeing that request.
