The difference between industrial polyaluminum chloride and domestic polyaluminum chloride Polyaluminum chloride is a polymer flocculant used in water treatment, industrial wastewater treatment is widely used, then the industrial use of polyaluminum chloride Is it the same as living polyaluminium chloride? What's the difference? The two are different. First industrial-grade polyaluminum chloride by the changing morphology of polycarboxylate complex composition, flocculation and sedimentation speed, suitable for a wide range of PH value, non-corrosive pipeline equipment, water purification effect, can effectively remove the water color SS , COD, BOD and arsenic, mercury and other heavy metal ions, the product is widely used in drinking water, industrial water and sewage treatment. The use of food-grade PAC is as, pure water disposal, drinking water disposal, for tanning, medicine, cosmetics and fine forging and other areas. In particular, white aluminum chloride can also be used for paper sizing precipitator, sugar bleaching brightener and so on. Food-grade white polyaluminium chloride in the sizing, retention of pulp, filter aid effect has also been a clear improvement. Second, the food level by the provincial health regulatory part of the supervision, because most of the food-grade water for the city's tap water supply to the city, so touch the food safety, so the regulation is harsh, promulgated by the enterprises ferry health permit. The rest of the food can be used in any industry, but the rest of the industry can only be used for industrial water disposal, industrial product additives, etc., can not be used in drinking water disposal and food additives.
