Polyaluminum Chloride Yellow Granules
Polyaluminum chloride (PAC) is an inorganic substance, a new water purification material, and an inorganic polymer coagulant. It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3. It has a high degree of neutralization and bridging effect on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions. The character is stable. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, the produced polyaluminum chloride is an inorganic polymer water treatment agent with relatively large molecular weight and high charge.
Properties of Polyaluminum Chloride
Polyaluminum chloride has the properties of adsorption, coagulation, precipitation, etc., poor stability and corrosiveness. If it accidentally splashes on the skin, rinse it off with water immediately. Production personnel should wear overalls, masks, gloves and long rubber boots. Polyaluminum chloride has the advantages of good spray drying stability, wide water area, fast hydrolysis speed, strong adsorption capacity, large alum flower formation, fast sedimentation, low turbidity of effluent, and good dehydration performance. Polyaluminum chloride is suitable for raw water with various turbidities, and has a wide range of pH values, but compared with polyacrylamide, its precipitation effect is far inferior to that of polyacrylamide.
