Anionic Polyacrylamide Powder For Sludge Pretreatment

There are two processes for the production of polyacrylamide, namely the copolymerization process and the homopolymerization process. Anionic copolymer pretreatment means use anionic copolymer(powder anionic) in pretreatment process.

At the pretreatment process, polyacrylamide anionic for sludge pretreatment is the first step to decrease SSvalue and COD value. Powder anionic will treat sludge or wastewater with inorganic polymers.

Use polyacrylamide powder for sludge pretreatment is a common practice. This type of polymer is powder anionic for sludge pretreatment. This reason is the particles in inorganic sludge usually carry positive charges. After powder anionic for sludge pretreatment dissolves in water, it releases negatively charged ionic groups. These negatively charged ions undergo electrical neutralization reactions with the positive charges on the surface of the sludge particles, reducing the electrostatic repulsion between the particles and thereby promoting the coagulation of the particles. The polymer chains of anionic copolymer pretreatment product have a very long length and can play the role of adsorption bridging between sludge particles. One end of it adsorbs on the surface of one particle, while the other end extends into the water and adsorbs another particle, thereby connecting multiple particles together to form larger flocs.

As a highly efficient flocculant, anionic polyacrylamide (APAM) powder can accelerate the sedimentation of suspended solids and improve the biodegradability of sewage through the adsorption - bridging effect during the sewage pretreatment stage (such as in the regulating tank and primary sedimentation tank). The core principles of using APAM powder in sewage pretreatment are "uniform dissolution, appropriate dosing, and synergistic cooperation". It is necessary to optimize the dissolution conditions and dosing parameters according to the characteristics of the sewage quality (pH, turbidity, type of pollutants). At the same time, proper storage protection and equipment maintenance should be carried out to maximize its flocculation effect, reduce treatment costs, and ensure operational safety.
