Sludge dewatering, as the name suggests, is to dehydrate the sludge after sewage precipitation, so that the sludge can be better treated. There are many kinds of sludge dehydrating agents, common are polyaluminum chloride, polyaluminum ferric chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide. So with so many drugs, how do you choose? Next, let Works Chemical Xiaobian discuss with you. Now many sewage treatment enterprises are still using common sludge dehydrating agents on the market, such as: polyaluminum chloride, polyaluminum ferric chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide and so on.

These traditional sludge dehydrants can reduce some of the moisture in the sludge. The use of these traditional dehydrators can only reduce the moisture in the sludge to about 80% and cannot be further reduced. In addition, the amount of these dehydrators is large, and they need to be used in combination with lime, which will also cause corrosion to the equipment, undoubtedly increasing the operating costs of the enterprise. So what other sludge dehydrants should be added to replace these traditional agents? Works Chemical Xiaobian take you to learn about the new sludge dehydrating agent.

The new sludge dehydrator independently developed by Works Chemical is a chemical agent that can change the surface structure of the sludge, reduce the surface load of the sludge solid, reduce the specific surface area of the sludge surface, 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.

After the use of sludge dehydrating agent, the sludge is filtered by the plate and frame filter press, the sludge flocculation is dense, the water content is very low, and the sludge weight loss is obvious. The moisture content of the sludge from the regulated filter press can be reduced to 40%-60%. The use of new sludge dewatering agent to treat sludge dewatering does not need to add lime, and the amount is small. It can also effectively improve the mud pressing efficiency of the plate and frame filter press, reduce the mud pressing cycle, and save sludge treatment costs for enterprises.
