Two-stage screw shaft mechanism enables even higher dehydration rate
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.
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 amount of backwash water is reduced.
