Polyaluminum chloride(PAC)

1. Molecular formula: [AL2 (OH) LnCL6-n] m
2. Appearance: white powder;
3. Specification: Drinking water
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 waste 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
Compared with other coagulants, this product possesses the following advantages.
1. Wider application, better water adaptation.
2. Quickly shape big alum bubble, and with good precipitation.
3. Better adaptation to pH value(5-9), and little declining range of pH value and alkalinity of water after treatment.
4. Keeping stable precipitation effect at lower water temperature.
5. Higher alkalization than other aluminium salt and iron salt, and little erosion to equipments
