Coagulant coagulation effect of polyaluminium chloride

Polyaluminium chloride coagulation effect is better than aluminum sulfate, it has a fast coagulation, the water quality good, the widely used water quality change, etc. For low temperature and low water, polymer aluminum still has good coagulation effect. 

用聚合氯化铝处理水，由于其有效成分含量高，故用药量少，仅为硫酸铝用量的1/2— — A third. Polymerization aluminum processing, water PH drop smaller, reducing the corrosion of water pipe line. Non-toxic product itself, the living water meet the national drinking water standard, the indirect economic benefit is remarkable. With polyaluminium chloride as a coagulant, can be more cost savings.

with the development of modern industry, represented by polyaluminium chloride of high polymer coagulant has been widely used in the field of water treatment. Because it is the most beautiful artificial precast concrete control form, put in the water can play a role of electrical neutralization and bridging flocculation, it compared with aluminum sulfate has more superiority and the widespread application value.

polyaluminium chloride coagulation mechanism, and through the industrial experiment, from theory and practice to justifying the water purification treatment technology in power plant, polyaluminium chloride than aluminum sulfate has more advantages. Water pretreatment of coagulation, clarification, filter bag. Coagulation treatment is coal-fired power plants in the first step of key water purification process, the coagulation effect is good or bad, directly affects the quality of the water pretreatment, and to a certain extent and influence subsequent desalination process. Coagulation treatment needs to select coagulants, traditional coagulants is mainly aluminum sulfate. Due to its put in the water, hydrolysis condition such as water quality environment restraint generated form, not the most effective flocculation and exert its maximum effectiveness.
