Why is the filter press non-stick filter cloth? How to solve it? The following Works Chemical sludge dehydrating agent manufacturers for you to answer this question, teach you how to solve the filter press non-stick filter cloth situation. There are many reasons why the filter press does not work. From the working principle of the filter press, the entire equipment provides filtration power through the water pump. At the beginning, the filter cloth is used as the filter medium, and after the formation of the filter cake, the filter cake is used as the filter medium to achieve the solid-liquid separation state. The filter plate of the filter press plays a supporting role to form the filter chamber.

When we know how it works, we can analyze the overwhelming common causes. First, when the filter channel formed by the filter cloth fiber is blocked, the filtered water flow through the channel is very small, or almost no. Of course, it's hard to get a dry filter cake. Moreover, if the particle size of the material is infinitely close to the filter diameter of the filter cloth, it is easy to block the filter cloth.

1.equipment reasons: filter cloth filtration performance is poor; Sludge specific resistance is too high; Low extrusion pressure, short extrusion time, pressure regulator failure.

2.the agent: in the sludge to add an appropriate amount of coagulant, coagulant and other chemical agents, the main role is particle flocculation. It makes dehydration difficult.

In view of the above problems, a new type of sludge dewatering agent can effectively solve the problem of incomplete dehydration of traditional chemicals. Sludge dehydrating agent is a kind of agent that can change the surface structure of sludge, reduce the solid surface load of sludge, reduce the specific surface area of sludge, and destroy the bacterial structure. The main components of sludge dehydrant change the surface properties of sludge through synergistic action, reduce the specific surface area of sludge, destroy the cell wall and cell membrane, release intracellular water, remove free water, bound water, capillary water and most of the biochemical sludge intracellular water.

Sludge dewatering agent contains water purification agent, organic polymer, sludge stripping agent, sludge surface treatment agent, wall breaking agent degreaser, sludge surface structure modifier and other components. Chemical agents that reduce the solid surface load of the sludge, reduce the specific surface area of the sludge surface, and destroy the structure of bacteria. After adding sludge dehydrating agent to the sludge, the water permeability of the sludge will be improved. For some special sludge, if it is still not dry after adding sludge dehydrating agent, it is recommended to increase the amount of sludge dehydrating agent. Good water permeability, suitable for plate and frame filter press dehydration.
