It has a high degree of electrical neutralization and bridging effect on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions with stable properties. Due to the bridging effect of hydroxide ions and the polymerization of multivalent anions, the produced polyaluminium chloride is an inorganic polymer water treatment agent with a large relative molecular mass and a high charge.
