Product Name: PolyAluminium Chloride /PAC
Polybasic aluminum chloride
Aluminum polyhydroxychloride
CAS No.: 1327-41-9
Polyaluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Properties
1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility.
4. It is slightly corrosive and easy for operation.
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

1. It is a flocculant.
2. Polyaluminum chloride is used as a water treatment agent in surface treatment.
3. the main raw materials of anti-sweat cosmetics.
4. some flocculants can be used as food additives. It is mainly used for purifying drinking water and special water quality treatment of water supply, such as removing iron, removing removing radioactive pollution, removing floating oil and so on. It is also used for industrial wastewater treatment, such as printing and dyeing wastewater.
