Audited Supplier Polyaluminium chloride (basic aluminum chloride). Polyaluminium chloride is an inorganic polymer coagulant. Due to the bridging of hydroxyl ions and the polymerization of multivalent anions, it produces inorganic polymer water treatment agents with large molecular weight and high charge The molecular formula is as follows: [al 2 (OH) n Cl 6-n] min is 3-5, m ≤ 10), in which the coagulation is shown as follows:. A. strong electroneutralization of colloidal substances in water b. The hydrolysate has excellent bridging adsorption for suspension in water c. Selective adsorption of solubility a. Polyaluminium chloride as a water treatment agent has strong adaptability to various water quality, especially for coagulation and sedimentation of high turbidity water b. The purified water quality is better than inorganic coagulants such as aluminum sulfate, and the water purification cost is 15-30% lower than that.
The colors of polyaluminium chloride generally include white, yellow and tan. Polyaluminium chloride of different colors also has great differences in application and production technology. Polyaluminium chloride with alumina content between 27% and 30% in the national standard range is mostly earthy yellow, yellow and light yellow solid powder. These types of polyaluminium chloride have good water solubility. In the process of dissolution, accompanied by physicochemical changes such as electrochemistry, coagulation, adsorption and precipitation, the flocs form quickly and coarsely, have high activity, precipitate quickly, and have obvious purification effect on high turbidity water.
