Polyaluminium chloride is a common water purification material and is often used as a flocculant in sewage treatment. White polyaluminium chloride is also known as a polymer coagulant. It is a white or milky white powder made by spray drying aluminum hydroxide powder and high-purity hydrochloric acid. It is very easy to melt when exposed to the air. White polyaluminium chloride has replaced aluminum sulfate as a neutral sizing precipitant in the papermaking industry.
Henan Xinhuan Polyaluminium Chloride Manufacturer used several polyaluminium chloride coagulants produced with different raw materials and processes, and conducted coagulation tests on raw water of several different water qualities. The effects of factors such as the dosage of coagulants and the time of floc formation were discussed, and the following conclusions were obtained:
(1) As the amount of coagulant added increases, the turbidity removal effect improves, but if the amount added exceeds a certain content, the improvement is not obvious. Therefore, in the coagulation test, it is very important to choose the most appropriate dosage.
(2) Under neutral conditions, that is, the pH value range is 6~8, the coagulation effect of PAC is the best.
(3) Polyaluminium chloride (PACSDD) containing high iron has good coagulation effect on low-temperature and low-turbidity water, with fast floc formation time and low residual turbidity after reaction.
(4) PAC products produced with bauxite and calcium aluminate powder show better coagulation performance than PAC products produced by other processes.
