In the current sludge treatment, polymer inorganic sewage flocculant is usually added for flocculation dehydration, that is, polymer bridge flocculation can neutralize the negative charge on the sludge, increase the cohesion of ions, and improve the performance of sludge dewatering performance. But the actual dehydration effect is not ideal. After dewatering with inorganic sludge flocculant, the water content of sludge is still as high as 80%. So is there a way to reduce the water content even lower?

In order to help our customers solve the problem of high sludge moisture content, our Works Chemical department, after unremitting efforts, finally independently developed a sludge synergist to improve sludge dewatering performance, and conducted research on it to improve sludge dewatering. Performance mechanism. After a large number of experiments and use in various industries, Works Chemical sludge synergists can effectively reduce the moisture content of customers to about 40%-60%, and some industries even reduce their sludge moisture content to 38%.

The main components of the sludge synergist change the surface properties of the sludge, reduce the specific surface area of the sludge, destroy the cell wall and cell membrane, release the water in the cell, remove free water, bound water, capillary water and cell water in most biochemical sludge, and inject the sludge conditioned by the sludge synergist into the filter chamber of the filter press at a pressure of about 1.0MP. It is beneficial for efficient filtration of free water in sludge. The accumulated sludge in the filter chamber reaches the design capacity of the filter press and enters the high-pressure pressing part.

The final dryness of the press dehydrated sludge is closely related to the effect of chemical conditioning modification, as well as the filling degree of the press chamber, the increase rate of press pressure and the retention time of press pressure. When the chemical conditioning achieves better results, the use of high pressure feeding and high pressure pressing can shorten the time of the entire press section and improve production efficiency. Automatic discharge and backblowing of filter material (filter cloth) are completed at the same time, which can reduce the labor intensity of the controller, and improve the efficiency of the completion of the action, and maintain the effect of the filter cloth to intercept sludge and permeable water.
