High purity Polyaluminum chloride(PAC) for drinking water

1. Molecular formula: [AL2 (OH) LnCL6-n] m
2. Appearance: white powder;
3. Specification: Drinking water
4. Pass ISO9001:2008
High-purity PAC is a kind of milk white powder. It is a kind of high-quality poly aluminum chloride which is water soluble and with low basicity. It can not only be used in the treatment of drinking water, city water and water for precision manufacturing, but also be used in paper-making, medicine, sugar liquid refining, cosmetics additives as well as daily chemical industry.

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
