Polyaluminium chloride water treatment chemical

Polyaluminium Chloride(PAC) is a new-type inorganic macromolecule coagulant with high efficiency. PAC is widely used in the industrial water purification, industrial effluent municipal sewage treatment. The one which use for drinking water treatment is manufactured by advanced process and raw materials of good quality.1. The water treatment cost is 20%-80% lower than that of other inorganic flocculants.2. PAC can lead to quick formation of flock with big size and rapid precipitation.3. PAC has wide-range adaptability to the waters at different temperatures and a good solubility.4. The liquid product is slightly corrosive and suitable for the automatic dosing and convenient for operation. Furthermore, it will not block pipes over long-time usage.

[ Uses ] 1. The liquid polyaluminium chloride can be dosed directly or dosed after dilution. Dilution is necessary before dosing for the solid product. The normal dilution ratio for the solid product is 2%-20%, and 5%-50% for the liquid product (based on weight percentage).2. The specific dosage is based on the flocculation tests and trials by the users. The usual dosage of the liquid product is 3-40 g/ton, and of the solid product, 1-15 g/ton.[ Packing & Storage ]The solid polyaluminium chloride(PAC) is packed in inner plastic bags and further in polypropylene woven bags, with each bag containing 25 Kg. The shelf life is 6 months for liquid product and 12 months for the solid product. Polyaluminium Chloride(PAC) should be stored in a dry and ventilated place, but the effect will not be affected even if it gets wet.
