Product Description:
Polyaluminium chloride PAC is divided into industrial grade and drinking grade. Industrial grade is divided into brown granule PAC and yellow granule PAC. The drinking grade is divided into yellowish powder PAC and white powder PAC.
Polyaluminium chloride is a kind of inorganic polymer coagulant, the color is yellow or pale yellow granules. It is formed by hydroxyl ions of bridging function and the order of anionic polymerization, the molecular weight and charge density are higher, the flocculation body forms fast, and the applicable range of PH value is 5-9.

Application Fields:
1. Water purification treatment: domestic water, industrial water;
2. Urban sewage treatment;
3. Industrial wastewater, sewage, sludge treatment and recovery of some slag in sewage, etc.;
4. For some industrial sewage that is difficult to treat, PAC is used as the matrix, mixed with other chemicals, and formulated into a compound PAC, which can achieve surprising results in sewage treatment.
During use, it is sometimes used in combination with polyacrylamide PAM(cationic polyacrylamide, anionic polyacrylamide, nonionic polyacrylamide) or PFS polymeric ferric sulfate according to the situation.
Usage, Packaging & Storage
1. Mix the PAC powder and water by 1:2.5- 1:3(weight ratio) about 30 minutes. After it is completely dissolved, then use it.
2. Before using, make a simple test according to the water quality characteristics, choosing the better way to use it.
3. The product is packed in a plastic bag lined with polyethylene bags, each bag is 25kg.
4. PAC should be stored in a cool and dry place, avoiding the sun and rain.
