In the process of industrial wastewater and domestic sewage treatment, a large amount of sludge will be produced. The moisture content in the sludge reaches 95% to 99%, as long as the water is removed, the volume of the sludge will be greatly reduced to facilitate further processing. However, because most of the sludge particles have a certain charge, the dehydration performance is very poor. The sludge dewatering agent independently developed by Works Chemical can achieve the deep dewatering of sludge. Works Chemical sludge dewatering agent is a chemical agent that can change the surface structure of sludge, reduce the surface load of sludge solid, reduce the specific surface area of sludge surface, and destroy the structure of bacteria.

The main components of sludge dewatering agent are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. Sludge dewatering agent has the advantages of less dosage, low cost, breaking the bottleneck of sludge dewatering, achieving efficient concentration and dewatering, good treatment effect and high cost performance. Sludge dewatering agent is widely used in the dewatering treatment of sludge in various industries such as living, printing and dyeing, paper making, electroplating, chemical industry and leather. The sludge dewatering agent combined with the plate and frame mud press can reduce the sludge moisture content from more than 90% to 40%-60%, and fully realize the sludge reduction.

After the sludge is conditioned with sludge dewatering agent, the pressure of about 1.0MP is injected into the filter chamber of the filter press to efficiently filter out the free water in the sludge, and the sludge accumulates in the filter chamber to reach the design capacity of the filter press. The final dryness of the press dehydrated sludge is closely related to the effect of chemical conditioning and modification, but also to the filling degree of the filter press chamber, the press pressure rate, the press pressure retention time, etc.

High pressure feeding and pressing can shorten the time of the whole press section and improve the production efficiency when the chemical conditioning sludge dehydrating agent achieves better effect. 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.
