The conditioned sludge flows into the filter zones from the flocculation tank and is pushed forward to the discharging end. With the gaps between the thread of the shaft is getting even narrower. The pressure on the sludge is getting higher and higher. Then the water is separated from the sludge and flows out from the gaps between the moving rings and fixed rings. The movement of the moving
rings will clean the gaps between moving and fixed rings and prevent the machine from blockage .. The filtered sludge cakes will be pushed forward by the shaft and finally discharged from the end.
. Replacing gravity type dehydrator to realize efficient concentration of sludge.
. Flocculation and concentration operating together makes dewatering easy.
. Optimize concentration of slurry for dewatering with solenoid control valve.
