How to choose a flocculant in wastewater treatment should be selected according to the characteristics of the wastewater in a specific industry, and at the same time, it also depends on where the flocculant is added and what purpose it is used for.

Bisacrylamide is a chemical substance with a molecular formula of C7H10N2O2. Bisacrylamide has two identical and very active reactive functional groups. It can be polymerized with a variety of ionic monomers to prepare ion exchange resins, and is polymerized with nitrogen and sodium acetate. In addition, it can also be used in medical, cosmetics and paper processing fields, and it has a wide range of uses.

The main component of microbial flocculants is microbial cells or their secondary metabolites. It has the characteristics of wide application range, high flocculation activity, safety, harmlessness, and easy biodegradability, so it can be widely used in the treatment of water supply, sewage and wastewater.

Poly(Dimethyl diallyl ammonium Chloride) is a cationic organic polymer with dimethyldiallylammonium chloride as the main body. It has good water solubility, and the aqueous solution is neutral, It has good dewatering performance for activated sludge.

PDMDAAC bentonite prepared by modifying bentonite with Poly(Dimethyl diallyl ammonium Chloride) has greatly improved its adsorption performance compared with the original soil. The decolorization rate of printing and dyeing wastewater is slightly higher than that of activated carbon, but the treatment time is far less than that of activated carbon.

The degree of treatment of water supply, sewage, and wastewater mainly depends on the flocculation characteristics of the microbial flocculant. Therefore, a better flocculation effect can be achieved through certain treatment conditions.
