a. Usage(PolyAluminium Chloride/PAC ) :
PAC is a kind of inorganic macromolecule flocculant. Through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adapts a wide pH range of 5.0~9.0, and the best is between 6.5~7.6.
1) Purification of river water, lake water and underground water
2) Purification of industry water and industry recycling water.
3) Purification of waster water
4) Reclaiming coal from coal-washing waste water and kaolin in ceramic industry
5) Purification of the waste water in printing and dyeing industry, leather industry, brewage industry, meat-processing industry, coal-washing, metallurgy industry, mine, pharmacy, paper-making, and purification of the waste water containing fluorine, oil and heavy metals
6) Tannage and cloth cockling-prevent
7) Cement Solidifying, and moulding
8) Refining of pharmaceuticals, glycerine and sugar
9) Catalyzer carrier
10) Paper-making glue
b. Storage(PolyAluminium Chloride/PAC ):
The products shall be sealed and stored in the dry and ventilated place to prevent from rain ,high temperature and strong sunlight .
c.Application method(PolyAluminium Chloride/PAC):
1)The liquid product can be used directly or used after dilution.Dilution is necessary before used for the solid product. The normal dilution ratio for the solid product is 5%-15%.
2)The specific dosage is based on the flocculation tests and trials by the users. The usual dosage of the liquid product is 3-40 g/ton, and of the solid product, 1-15 g/ton.
