Polyaluminium chloride is an inorganic polymer coagulant. It is an inorganic polymer water treatment agent with large molecular weight and high charge due to the bridging of hydroxyl ions and the polymerization of multivalent anions.
The flocculation of polyaluminium chloride is shown as follows:
a. Strong electroneutralization of colloidal substances in water
b. Excellent bridging adsorption of hydrolysates on suspended solids in water
c. Selective adsorption of soluble substances
Polyaluminium chloride application:
1. Urban water supply and drainage purification: River water, reservoir water and groundwater.
2. Industrial water purification
3. Urban sewage treatment
4. The recovery of useful substances in industrial wastewater and waste residue, the promotion of the sedimentation of pulverized coal in coal washing waste water, and the recovery of starch in starch manufacturing industry.
5. Various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine-containing wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater F, sewage treatment.
