Food Grade PolyAluminium Chloride White Powder Drinking Water Purification
PolyAluminium Chloride Drinking Water Water Purification
Food-grade polyaluminium chloride (PAC) is a type of PAC that is suitable for use in drinking water treatment. It is made from high-purity raw materials and does not contain any harmful impurities or additives.
Bluwat PAC-01 is white powder polyaluminium chloride which is mainly used for drinking/potable water treatment and the paper industry.
Polyaluminium Chloride is a high-effective inorganic polymer coagulant. It is widely applied in water purification, drinking water treatment, paper production, and daily chemicals.
CAS No.:1327-41-9 EINECS No.:215-477-2 Molecular Formula:【AL2(OH)nCL6-n】
The White Poly Aluminium Chloride production process is the most advanced technology of the spray drying method.
PAC is easy to be damp when it is exposed to the air.
Strong electric neutralization of colloidal substances in drinking and potable water.
The PAC solution has good adsorption bridging function for suspended solids in water.
Selective adsorption of soluble substances.
Effectively remove the color matter, SS, COD, BOD, and arsenic(As), mercury(Hg), and other heavy metal ions of the drinking & potable water.
Main Application Fields
White Powder(Spray) Polyaluminium Chloride is specialized inorganic aluminum salts chemicals for drinking water treatment.
Paper Making Sizing Agent & Sugar Decolorization Chemical
Polyaluminium Chloride Advantages: |
| Low dosage than Aluminium sulfate, low cost |
| Quick formation of big flocs and rapid precipitation. |
| Wide adaptability and good solubility. |
| Slight corrosive and easy to operation |
| Do not block the pipes over long-time usage. |
| Higher purity of raw material Al(OH)3 and HCl. |
Polyaluminium Chloride Usage:
1. For solid PAC, dilution is necessary before being dosed. The dilution proportion for a solid product is 2%-20%, and for a liquid product, 5%-50%(based on weight percentage).
2. The specific dosage is based on the flocculation test and on the trial. Normally, the dosage of solid is 1-15g/MT, the dosage of liquid product is 3-40g/MT
3. Its acidity is lower than other inorganic coagulants.
4. The PAC solution can not be placed for more than one week.
PAC Packing&Storage:
1.25kg/polypropylene woven bags with an inner plastic bag.
2. Warranty for 2 years.
3. Keep in a dry and ventilative place
