Model Reference

Wet sludge treating capacity=dries sludge treating capacity ÷SS(DS means dries sludge)

The figures are only for reference.According to the different characteristics of sludge, there will be deviation in the amount of treatment, please consult our company when you select the type for details .
 Sludge treatment progress 
Multi-disk screw press, also known as MDS dewatering press, is a kind of cutting edge sludge dewatering equipment with non-clogging design and low energy consumption, especially applicable for oily sludge.

Dewatering Principle
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.

Installation Instructions

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.
