How to improve the efficiency of filter press in industrial wastewater treatment operation

Dec 27, 2020

Generally, we need the coordination and adjustment of many equipment during the operation of industrial wastewater treatment projects. Then let's talk about the solutions to improve the efficiency of filter presses. Here is a brief introduction:

1. Reduce the moisture content of the sludge in the thickening tank

Reducing the water content of the sludge thickening tank can reduce the use time of the filter press, but this method is not easy to master, if it is not mastered, it will easily affect the quality of the effluent;

2. Increase the proportion of activated sludge in the thickening tank

Before pressing the mud, it is necessary to inject the active excess sludge from the secondary settling tank into the thickening tank to increase the proportion of activated sludge in the thickening tank to ensure subsequent mud pressing operations;

3. Control the proper ratio of mud and medicine

After the mud medicine is mixed on the machine, the solid-liquid separation effect is good, and tiny sludge particles can be formed. The free water can quickly seep through the filter cloth. After the sludge and the filter cloth are separated at the outlet, there is no sticky dirt on the filter cloth. mud;

Fourth, master the PAM concentration

The PAM concentration is between 0.6‰ and 0.8‰, which can reduce the moisture content of the sludge to between 60% and 70%;

Five, to ensure that the filter cloth passes

Six, to ensure the stable operation of the filter press
