3.Application

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
