Previously explored avenues:
choice of polymer and dosage
optimal use of thickener
control of belt speed and cleaning of filter cloths
and for better sludge drainage, a PVC pipe is placed on the belt, before the claws. The pipe is free (no pressure control).
Do you have use any other methods?
Hello, do you place the PVC pipe between incoming sludge and the first claws? Do you use a pipe with a diameter of 63?
We tested a wastewater pipe d160 (thickness 4 mm) placed after the claws. We will use a d125 week next with a plate setting of 4 mm from the filter cloth.
Hello Alain, another simple solution is to make use of the pressing roller near the discharge hopper. There are different models; some rollers can be filled with water to boost their weight; other have switch plates to control height. On that type of unit, it is easy to add switch plate (welded or bolted to the chassis) at each end of the roller and resting on a screw
system (welded nut and stainless steel screw D16) on the roller support arms. This enables you to regulate not just roller height but also pressure. Good day.
