With the improvement of people's living standards and the rapid development of the clothing industry, more and more sludge is generated in the process of fabric processing, printing and dyeing. Printing and dyeing sludge is characterized by a large number of polymer organic fibers, residual dyes and inorganic minerals, high water content, high viscosity. The composition of textile printing and dyeing sludge is very complex and contains a lot of heavy metal elements. A new sludge dehydrator developed and manufactured by Works Chemical.

Works Chemical- Sludge conditioner, sludge dewatering synergist manufacturer

The new sludge dehydrating agent is a chemical agent that can change the surface structure of the sludge, reduce the solid surface load of the sludge, reduce the specific surface area of the sludge surface, and destroy the bacterial structure. The main components of the new sludge dewatering agent are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. The combination of the new sludge dewatering agent and the plate and frame mud press can make the moisture content of the sludge from more than 90% to 40% to 60%, and the sludge reduction can be fully realized.

The sludge printed by the new sludge dehydrating agent is injected into the filter chamber of the filter press at a pressure of about 1.0MP, which is conducive to efficient filtration of free water in the sludge. After the accumulated sludge in the filter chamber reaches the design capacity of the filter press, it enters the high-pressure press stage. 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 the new sludge dewatering agent can improve the efficiency of the completion of the action, and maintain the effect of the filter cloth to block sludge and permeate water.
