As an inorganic polymer coagulant, polyaluminum chloride (PAC) offers advantages such as strong adsorption, excellent flocculation, rapid hydrolysis, large floccules, rapid precipitation, excellent dehydration, and low effluent turbidity. It can also effectively remove color and heavy metal ions such as arsenic and mercury from water. The polyaluminum content we generally refer to is the aluminum oxide content in the polyaluminum, with commonly used standards such as 31%, 30%,28%, 26%, and 24%. The higher the aluminum oxide content, the higher the price.

Since the water company issued new regulations regarding source water treatment, most regions have been required to switch from yellow polyaluminate to the current white food-grade polyaluminate. This white polyaluminate boasts a high aluminum oxide content, exceeding 29.5%. It also features a low basicity, low insoluble matter, no excess heavy metals, and low iron content. However, it is also relatively expensive and is primarily used by waterworks, purified water plants, pharmaceutical factories, food factories, cosmetics factories, and other high-standard and demanding industries.
Polyaluminate with a content of 28% or more can be used in high-turbidity wastewater treatment industries such as metallurgical plants, paper mills, steel mills, and plastics factories. This type of polyaluminate has fewer impurities, faster flocculation, and higher purity. Polyaluminate with a content of 26% or more is more suitable for treating low-turbidity water sources, such as municipal wastewater treatment. Polyaluminum with a content of 24% is cheaper than that with a higher content, but it produces relatively more sediment. It is more suitable for the treatment and purification of industrial wastewater with high turbidity, such as coal washing plants, printing plants, mine wastewater, etc. It has ideal effects and low costs. However, it is worth noting that the source water of different industries is different, and the water quality of the same industry is also different. Before sewage treatment, it is necessary to find the optimal dosage and cooperate with other agents to achieve the best treatment effect. The higher the content, the better. The more suitable it is, the better.
