PAC 30% Polyaluminium Chloride Water Treatment

Wastewater Treatment Chemicals PAC 30% Poly Aluminium Chloride Granule

Polyaluminum chloride is an inorganic polymer coagulant with the molecular formula [Al2(OH)nCl6-n·xH2O]m(m≤10, n=1～5). It is an inorganic polymer compound, which is a hydrolysis product of aluminum chloride and aluminum hydroxide. Due to the bridging effect of hydroxide ions and the polymerization effect of polyvalent anions, an inorganic polymer water treatment agent with larger molecular weight and higher charge is generated. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, an inorganic polymer water treatment agent with larger molecular weight and higher charge is produced. From the morphological point of view, it can be divided into solid and liquid. The solid is divided into brown, yellow and white according to the different color. Different colors of polyaluminum chloride also have big differences in application and production technology.

Product performance

a. As a water treatment agent, polyaluminum chloride has strong adaptability to various water quality, and is particularly effective 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. Flocs form fast and settle quickly.
c. High alumina content and small dosage, which can reduce the cost of water.
d. The source water PH value can be condensed in the range of 5.0-9.0.
e. Low corrosiveness, good operating conditions, and better solubility than aluminum sulfate.
f. There is less salt in the treated water, which is conducive to ion exchange treatment and pure water preparation.
g. The adaptability to the temperature of the source water is better than that of inorganic coagulants such as aluminum sulfate, and the treatment effect of low temperature water is also better. The minimum precipitation temperature is -18°C.
