PAC Polyaluminium Chloride Inorganic Polymer Coagulant White Powder
Polyaluminium chloride (PAC) is an inorganic substance, a new type of water purification material and inorganic high-molecular coagulant, commonly known as polyaluminum. It is a water purification material, an inorganic high-molecular coagulant, also known as polyaluminum, with the English abbreviation PAC. It is an inorganic high-molecular water treatment agent with a large molecular weight and high charge, produced due to the bridging effect of hydroxide ions and the polymeric effect of multivalent anions. In terms of form, it can be divided into two types: solid and liquid. Solids are further classified by color into brownish, beige, golden yellow and white. Liquids can be colorless and transparent, slightly yellow, light yellow to yellowish brown. Polymeric chlorine of different colors in aluminium oxide also has significant differences in application and production technology.
Characteristics of polyaluminium chloride
1. Polyaluminium chloride is chemically stable at room temperature and does not deteriorate after long-term storage. When exposed as a solid, it is prone to absorbing moisture but does not deteriorate. It is non-toxic and harmless.
2. The PH range of water it can adapt to is 4 to 14, but the optimal treatment range is 6 to 8.
3. It has strong adaptability to water body treatment, fast reaction, low chemical consumption, low water production cost, large flocs, fast sedimentation, good filtration performance, and can improve equipment utilization rate.
