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.
As far as sewage treatment is concerned, both have their own merits. Polymeric Aluminium Chloride is widely used in the country, adaptable to a wide range of water. It is easy to form large alum flowers quickly and has good precipitation performance. Suitable PH value of the country wide (between 5-9), and after treatment of the water PH value and alkalinity decline is small. When the water temperature is low, it can still maintain stable precipitation effect. Alkalinity is higher than other aluminum salt and iron salt, and the erosion effect on equipment is small. Polyacrylamide can enhance the efficiency of 20% in sewage treatment than polymerized aluminum chloride, especially in sludge dewatering, polyacrylamide has its unique superiority, and in the recycling of water, it can enhance the recycling rate of water, and reduce the cost of enterprise operation. Especially in the scarcity of water resources and the deterioration of the water environment nowadays, polyacrylamide shows more superiority in Water Treatment. In some aspects, Polyacrylamide and Polymeric Aluminium Chloride used in conjunction, can achieve better water treatment results.
