Poly-aluminium Chloride, short for PAC, is a new type high performance inorganic macromolecule flocculating agent. It\'s hydrolysis product of AlCl 3 and Al(OH)₃ , and polymerized & bridged through hydroxyl group. And its molecular formula is [Al₂(OH)_n Cl₆ -n · xH₂O] m (m ≤ 10,n=1-5)

The Poly-aluminium Chloride is freely soluble into water, and has quite strong adsorptivity, many physic & chemical reaction, such as sedimentation, adsorption, agglutination, and electric chemistry, happen during hydrolysis process. This product is mainly used in purify of drinking water and treatment of industry waste water, such as the radioactive material, leady (Pb++) chromate (Cr+++) high toxicity heavy metal and fluoride (F) waste water. Furthermore, it also widely used in precision casting, papermaking, tanning and some other fields.

Using and packing method

1. When use solid product, make 5-10% solution first, then dilute to request concentration; during the dissolution, add the water and mix slowly, the diluted solution should be used up in 24 hours to avoid hydrolysis and reduce the effect. The dose quantity of this product is based on water resource haziness and purifies facility, the coagulating sedimentation test is needed to ensure the best dosing quantity.

2. Use the polyethylene plastic barrel to store liquid Poly-aluminium Chloride, the net weight of each barrel is 25kg, 50kg or 200kg. And covered with double cover, fasten the inner cover, screw the outer cover. The liquid Poly-aluminium Chloride can also be transferred by tank vehicle. The solid Poly-aluminium Chloride is packed by double bag, the net weight of each bag is 25kg, inner bag is plastic bag, and outer bag is plastic basket bag. The product should be stored in dry, airy warehouse and avoid drench and breathing.
