Poly aluminium chloride/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) Poly aluminium chloride/PAC can purification of river water, lake water and underground water
2) Poly aluminium chloride/PAC can purification of industry water and industry recycling water.
3)PAC can purification of waster water
4)Poly aluminium chloride/PAC can reclaiming coal from coal-washing waste water and kaolin in ceramic industry
5)Poly aluminium chloride/PAC can 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
Packaging and storage for Poly Aluminium Chloride (PAC):
1, lined with plastic bag, the outer layer is a plastic film packaging bags, each bag weighs 25kg.
2, stored in a cool, dry place, prevent the sun and rain.
