Polyaluminium Chloride


Polyaluminium chloride(aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts.
CAS No.: 1327-41-9

    PAC Feathures

    1. Using PAC as flocculant, the speed of flocs forming and settling is quick. Flocs formed is easy to filter
    2. Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better.
    3. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9
    4. Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed.
    5. There is fewer salts in water treated with PAC, this is good for high purity water purifying and ion-exchange treatment
    6. The corrosivity of PAC is lower, easy to transfer, handle and operate.

    PAC Applications

    1. Drinking water and sanitary sewage.
    2. Industrial water, industrial waste water, mine and water for oilfield injection, chemical waste water in industry of paper-making, metallurgy, washed coal and leather.
    3. Industry and makes waste water recyclable: paper-making glue, printing and dying, concrete hardener, precision casting hardener, glycerine refinement, crease-resistant for fabric, medicine, cosmetics and etc.
    4. Oil-water separation and has good effects in the oil refining industry.
