Product Description


Multi-plate screw type sludge dehydrator follows the dewatering principle of force-water homo-direction, thin layer dewatering, proper pressure and extension of the sludge dewatering path.

Dewatering pricinple
The initial section of dewatering drum is the thickening zone, where the solid-liquid separating process takes place and where the filrate will also be discharged.The pitch of the screw and the gaps between the rings decrease at the end of dewatering drum, hence increasing its internal pressure. At the end, the end plate further increases the pressure, so as to discharge dry sludge cake.

Manual operate
1. Prepare PAM in advance
2. open sludge pump, dosing pump., mixer in the floccultation tank .
3. open the sludge dewatering machine ,when the flocculation tank is full.
Notice :the water content of the sludge is very high at the beginning and even the water is normal, and the sludge will gradually become sludge. After working for a period of time, adjust the frequency conversion according to the actual situation of the sludge.
Once sludge is ok ,then can use auto mode.
1.Provide equipment certification and installation operating instructions.
2.Provide one-year spare parts.
3.Provide technical advisory services.
4.Provide guidance staff for installation and commissioning.
