What is the role of cationic Polyacrylamide in the desliming process of wastewater treatment?

 1. Promote the rapid precipitation of sludge: cationic Polyacrylamide is a kind of macromolecule organic matter, which can react with the suspended solid particles in the sewage to form the complex which is easy to precipitate. The use of cationic Polyacrylamide can promote the rapid accumulation of sludge particles and the formation of larger sediments, and improve the settling rate of sludge.

 2. Improving sludge sled pressing performance cationic Polyacrylamide can improve the rheological properties of sludge, increase its shear resistance and viscosity, thus improving the sludge in the sled press dehydration efficiency. The use of cationic Polyacrylamide can reduce the water content of sludge, reduce energy consumption and operating costs of dewatering equipment. 

3. Improving the transparency of the sludge filtrate: cationic Polyacrylamide interact with colloidal particles in the sludge to change their surface charge state and reduce inter-particle adsorption, the contribution of colloid particles to the turbidity of filtrate is reduced, thus the transparency of filtrate is improved. Four. Reduce the content of ammonia nitrogen and heavy metals cationic Polyacrylamide have strong adsorption capacity, can adsorb ammonia nitrogen and heavy metal ions in the sludge, reduce their content in the sludge. It is of great significance to reduce the discharge of harmful substances and improve the environmental performance of treated sludge.
