What is Coax Reverse Rotation Screw Press Dewatering Device / DBSP series?

Two-stage screw shaft mechanism enables even less water content

◆Stable Operation
A thorough squeeze of sludge is achieved by fine adjustment to the sludge properties. By eliminating a back pressure plate, leakage and blockage of dehydrated(dewatered) cake hardly occur.

◆Easy Operation
Change of sludge properties can be easily dealt with by adjusting the frequency of two motors. The rear stage shaft (plug screw) can forcibly discharge dehydrated cake.

◆High thickening efficiency
By using KDS Separator for pre-thickening, the amount of sludge recovery, the treatment capacity and the dewatering ability are greatly increased. Besides, the need for backwash water is reduced.
