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, usually add polymer inorganic sewage flocculant (sludge dewatering agent) for flocculation dehydration, that is, the use of polymer bridge flocculation can also neutralize the negative charge on the sludge, increase the cohesion of ions, and improve the sludge dehydration characteristics.
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? Yes, in order to help our customers solve the problem of high sludge moisture content, after unremitting efforts, our 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 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 type mud press, the moisture content of the sludge can be greater than 90% ~ 40%-60%, and the sludge reduction can be fully realized. Sludge dehydrating agent is a new organic sludge dehydrating agent developed by Works Chemical. The new sludge dehydrating agent is a chemical agent which 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 of the new sludge dewatering agent are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on.
The sludge moisture content after treatment with plate and frame filter press and new sludge dehydrating agent can be reduced from more than 90% to 35%-55%, and the sludge reduction can be fully realized. So what are the advantages of the new sludge dewatering agent compared with the traditional water treatment agent? The amount of traditional water treatment agent is large, and it needs to be used with lime, which not only has low production efficiency and poor dehydration effect, but also causes corrosion to the dehydration equipment, resulting in clogging of the filter cloth, and greatly increases the operating cost of the enterprise. The new sludge dewatering agent used with the plate and frame filter press can not only greatly improve the mud press efficiency of the plate and frame filter press, but also reduce the mud press cycle. It will not corrode the equipment, will not block the filter cloth, and save high operating costs for enterprises.
