Polyacrylamide (PAM) is an organic flocculant. According to its molecular chain with different groups, can be divided into anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide and amphoteric polyacrylamide. acrylamide and amphoteric polyacrylamide. Polyacrylamide is mainly used in smelting, textile, printing and dyeing, coal washing, pharmaceuticals, sugar purification, geological exploration, petrochemicals, oil mining and sewage treatment. In sewage treatment, polyacrylamide mainly plays the role of adsorption and bridging, the interaction between the charge, so that the fine particles to form larger flocs, so that it settles.
Polymeric Aluminium Chloride (PAC), is a kind of inorganic polymer flocculant, due to the bridging effect between hydroxide ions and polymerization of multivalent anions and the production of higher molecular weight, charge Higher inorganic polymer water treatment chemicals. Polymeric Aluminium Chloride is mainly used in the purification of surface water and groundwater, urban sewage treatment, recovery of useful substances in industrial waste water and waste residue. It is also widely used in printing and dyeing, leather, paper making, coal washing, food processing, sugar refining, cosmetics and other industries.
Polyacrylamide and Polymeric Aluminium Chloride are collectively known as flocculants, polyacrylamide is an organic flocculant agent, polymerized aluminum ammonia is an inorganic flocculant, both have a wide range of applications in various fields.
