2.PAM can be used for dewatering sludge; in industrial water treatment, it is mainly used as a prescription medicament, and when the water temperature is low, it can still maintain a stable precipitation effect. The alkalization degree is better than that of other aluminum salts in raw water treatment. Raw water treatment, the use of organic flocculant PAM instead of inorganic flocculant, PAM and activated carbon used in conjunction with, can be used for living water suspended particles in the cohesion and clarification; in sewage treatment, the erosion of the equipment is small. So the effect of polyacrylamide Better, suitable for a wide range of water, easy to quickly form a large alum, precipitation performance is good.Appropriate range of PH value is wide (5-9), and the treated water PH value and alkalinity decreased slightly.Polymeric aluminum chloride Is PAC, PAC wide range of applications.In the sewage treatment, the use of PAM can increase the reuse rate of water recycling, even if not to transform the sedimentation tank, water purification capacity can be increased by more than 20%, so many large and medium-sized cities in the water supply Or poor water quality, are using PAM as a supplement
