Anionic polyacrylamide is known as APAM in English. Anionic polyacrylamide is a kind of polymer flocculant, which is widely used in water soluble polymer series products. Its molecular weight is relatively large, generally around 18 million. It plays a very effective role in adsorption, flocculation and precipitation. It is also a widely used product.
The general method of wastewater treatment is to produce a precipitate, which is a substance that is insoluble in the reactants in the solution produced during a chemical reaction. In the sense of the word, it is the action of gravity removed by precipitation. The suspended matter in sewage can be a physical process, simple and effective, is one of the important technologies of sewage treatment.
Polyacrylamide has the advantages of high molecular weight structure, low dosage and low cost per unit volume of sewage treatment. Polyacrylamide is undoubtedly a promising flocculating product until lower cost and better flocculating products are developed.
