Municipal sludge is a precipitated substance produced in the water treatment process of urban sewage treatment plants, which contains a large number of microorganisms, mechanical properties and rich nutrients such as nitrogen and potassium, as well as excessive heavy metals and pathogenic microorganisms. Sewage treatment plant municipal sludge is the main source of sludge in China, and the sludge content is high, more difficult to dehydrate than industrial sludge.

The moisture content of municipal sludge is very high, and the treatment effect of traditional sludge dewatering equipment is general, which is difficult to dehydrate municipal sludge deeply, and it is unrealistic to recycle the treated sludge. Sludge moisture content is still high, difficult to transport, difficult to stack.

So how to reduce the moisture content of municipal sludge has also become a major problem in front of the environmental protection industry. To solve this problem, Works Chemical has independently developed a new sludge dewatering agent - sludge enhancer 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 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 mud press, the sludge moisture content can be reduced from more than 90% to 40%-60%, and the sludge reduction can be fully realized.
