PAC and PAM are often mentioned together in sewage treatment, so what is the difference and connection between them?

PAC is polyaluminum chloride, also known as water purifier. It is a flocculant and coagulant for sewage treatment, and it is widely used in the current sewage treatment field. The treatment effect is good, the operation is simple, and the economic cost is low. According to technical indicators, it is divided into drinking water grade and industrial grade. The most important is the content of aluminum oxide (AL2O3), which is generally between 22% and 31%. According to the production process, it is divided into drum drying and spray drying, both of which have their own characteristics and effects in different fields of sewage treatment.

PAM is polyacrylamide, which is currently the most widely used water treatment flocculant in China with the best treatment effect. Polyacrylamide is a linear polymer inorganic flocculant, which can be divided into anionic, nonionic and cationic according to ionic type. Different ionic types, molecular weights and ionic degrees have good applications in different fields.

PAC and PAM are both water treatment flocculants. In the field of sewage treatment, they dissolve with suspended impurities in water to form colloidal flocs. By stirring, etc., large and dense vanadium flowers are formed and flocculated and precipitated. PAC and PAM are used together when treating sewage. The combination of the two can not only achieve the best processing effect. At the same time, the dosage of the two chemicals will be reduced, and the cost of sewage treatment will be reduced, and the economic cost will be minimized.
