Poly Aluminium Chloride in all form, is extensively used as an industrial coagulant and Flocculent in different industries. Different grades of PAC are available for different purposes. PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro - organisms and colloidal particles, silt and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum.

Name: poly aluminium chloride

Short Name: PAC

Formula: Aln(OH)mCl(3n-m); 0<m<3n

CAS No.: 1327-41-9

Hs No.: 2827320000


 PAC Product Type     



Drum drying type polyaluminium chloride

Poly aluminum chloride is produced by the traditional process drum dryer polyaluminum chloride, the process is simple, low production costs, good product stability, wide adaptation to water, strong adsorption capacity, the formation of alum large, dense sedimentation fast, Products cost-effective, widely used in domestic waterworks and various types of sewage treatment companies. 


Spray drying type poly aluminium chloride

Spraying polyaluminium chloride is produced by spraying tower polyaluminum chloride, with good stability, wide adaptation to water, hydrolysis speed, strong adsorption capacity, the formation of alum large, dense sedimentation fast, low water turbidity, Dehydration performance is good.










White poly aluminium chloride

By the aluminum hydroxide powder and high purity hydrochloric acid spray-dried processed from a white or milky white powder-like fine powder, bare in the air easily melted. In recent years, white polyaluminum chloride has replaced aluminum sulfate as a neutral sizing agent in the paper industry.

PAC Use Method

1. Solution Preparation: The dissolve rate of PAC is 5%. It means dissolve 50g PAC into 1L water. The water is tap water or purified water.

2. Dissolve Time: The time is 5-10 min if you fully stir for dissolve.

3. Dosage: Get water sample and confirm optimum dosages by test.
