1. Overview of mud moisture content of plate and frame filter press:

In response to the national call for sludge reduction, many industrial and municipal sewage treatment stations have replaced belt filter presses, centrifuges, and spiral stackers with high-pressure diaphragm plate and frame filter presses, plate and frame filter presses, ultra-high pressure plates, and frame filter presses. Many customers reflect that the mud pressed out after the replacement of the plate and frame filter press has high water content, and even does not contain mud, and there is sandwich mud. Or using many different reagents will not reduce the moisture content. In view of the above problems, our company will elaborate on this problem.

The reason for the high moisture content of the mud pressed by the plate and frame filter press:

(1) Feed directly without adding sludge conditioner

(2) There are more hydrophilic groups on the surface of the sludge, which can not effectively release excess water.

(3) The sludge and the sludge conditioner are not fully mixed, and the mixing is not uniform.

(4) Low solid content of sludge before filtration

Second, how to solve the high moisture content of the mud pressed by the plate and frame filter press?

(1) Select the right sludge conditioner

(2) Let professional and technical personnel go to the site to debug and determine the best addition amount and method

Iii. Summary

Compared with the centrifuge, spiral stacker and belt filter press, the water content of the mud pressed by the plate and frame filter press is lower, but why the water content is high and cannot be reduced. Selecting suitable sludge conditioner can greatly improve feed efficiency and reduce sludge moisture content.
