Differences and connections between PAC and PAM
PAC and PAM are often mentioned together. What are the differences and connections between them?
PAC is polyaluminum chloride, also known as water purifier. It is a flocculant and coagulant for sewage treatment. It is widely used in the field of sewage treatment. Good treatment effect, simple operation, low economic cost. According to the technical index is divided into drinking water grade, industrial grade, the main content of aluminum oxide (AL2O3), generally between 22%-31%. According to the production process, it can be divided into drum drying and spray drying, which have their own characteristics and effects in different sewage treatment fields.
PAM is polyacrylamide, is currently the most widely used in China, the best treatment effect of water treatment flocculant. Polyacrylamide is a linear polymer inorganic flocculant, according to the ionic type can be divided into anionic, non-ionic, cationic, according to the technical index is divided into molecular weight 8-22 million, ionic degree 10-60. Different ionic type and molecular weight, ionic degree, in different fields have a good application.
PAC and PAM belong to the same water treatment flocculant, in the field of sewage treatment after its dissolution and water impurities suspended matter, forming colloidal floc. By stirring, forming large and dense vanadium flowers, and flocculation precipitation. PAC and PAM will be used together in sewage treatment. The combination of the two can not only achieve the best treatment effect. At the same time, the dosage of the two agents will be reduced, and the cost of sewage treatment will be reduced, and the economic cost will be minimized.
The difference between PAC and PAM is that polyaluminum chloride is a coagulant, which acts as a bridge in sewage treatment and attracts flocculation to each other. But polyacrylamide belongs to the polymer inorganic flocculant, in sewage treatment effective molecular chain reaction with sewage, forming colloidal floc so as to achieve the best results.
