Sludge is a by-product of municipal sewage treatment. With the acceleration of urbanization, the amount of sewage is also increasing, and the output of sludge is also increasing. The sludge has high water content and contains a lot of toxic and harmful substances. If not handled properly, it will cause secondary pollution. Traditional sludge disposal methods include landfill, incineration, land use, etc., but due to the high water content of sludge, its application is limited. Therefore, reducing the moisture content of sludge is the key to solve the problem of sludge treatment. 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 dewatering performance of the sludge. 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%.

In order to help our customers solve the problem of high sludge moisture content, our WORKS CHEMICAL Research and development department has independently developed sludge conditioners to improve the dewatering performance of sludge and investigate the mechanism of improving the dewatering performance of sludge. Through a large number of experiments and applications in various industries, WORKS CHEMICAL's sludge conditioner has been able to effectively reduce the water content of customers to around 40%-60%, and some industries have reduced their sludge water content to 38%.

Sludge conditioner is a chemical 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 structure of bacteria. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on. Combined with the plate and frame mud press, the sludge moisture content can be reduced from more than 90% to 40%-60%, and the sludge reduction can be fully realized.

The main components of the sludge conditioner change the surface properties of the sludge, reduce the specific surface area of the sludge, destroy the cell wall and cell membrane, release intracellular water, and then remove the free water, bound water, capillary water and intracellular water in most biochemical sludge.

The use of high pressure feeding and pressing can shorten the time of the whole press section and improve the production efficiency when the chemical conditioning achieves better results. The automatic discharge and reverse blowing of the filter medium (filter cloth) are completed at the same time, which can not only reduce the labor intensity of the control workers but also improve the efficiency of the completion of the operation, and maintain the effect of the filter cloth intercepting sludge and permeation.
