Wastewater Treatment Chemicals 31% PAC Drinking Grade Poly Aluminium Chloride
According to its content, polyaluminum chloride has three colors: white, yellow and brown. Different colors of polyaluminum chloride are also very different in application and production process. In the national standard, the polyaluminum chloride with a content of 28%~31% of alumina trioxide is mostly earthy yellow to yellow, light yellow solid powder. It is a new type of high-efficiency inorganic polymer coagulant. It uses advanced manufacturing technology and high-quality raw materials. It has the characteristics of less impurities, large molecular weight and good coagulation effect. Compared with other coagulants, polyaluminum chloride has the following advantages: wide application range and wide adaptability to water. It is easy to quickly form large alum flowers and has good precipitation performance. The suitable pH range is wide (between 5-9), and the pH and alkalinity of the water after treatment will decrease slightly. When the water temperature is low, the stable precipitation effect can still be maintained. The alkalinity is higher than other aluminum salts and iron salts, and has little corrosive effect on equipment.
