The biochemical sludge in domestic sewage treatment plant is difficult to dehydrate, which can be improved by adding sludge conditioner (sludge dehydrating agent). Sludge conditioner (sludge dehydrating agent) 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 of sludge dewatering agent include inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on. These agents reduce the amount of water in the sludge, making it more susceptible to dehydration. The use of sludge dehydrating agent can effectively improve the mud pressing efficiency of plate and frame filter press, reduce the mud pressing cycle, and save sludge treatment costs for enterprises.

When selecting and using sludge dehydrating agents, they should be selected according to the nature of the sludge and the target treatment effect, and used in strict accordance with relevant regulations and requirements. At the same time, attention should also be paid to the dosage of the drug, mixing methods and other issues to ensure the effectiveness and safety of the drug.

Please note that any decision to add a chemical should be made only after adequate research and testing to ensure that its environmental, human and process impacts are fully considered.
