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.

PAC Production Technology
According to different drying technique, there is two type poly aluminium chloride, drum drying type pac and spray drying type pac
PAC Package & Storage
Package: 25kg/bag, 20-23mt/container
It is packed in polypropylene woven bag with plastic liner
Storage: Expiration date is more than 1 years
It should be stored in cool and dry place
It still can be used if the poly aluminium chloride is affected with moisture
Common problems of polyaluminum chloride
Diluted PAC will affect the effect of it
When the water temperature is low, can still maintain a stable precipitation effect, rich water purification materials Xiaobian that widely adapted to water. Ea
What is the difference between aluminum white and yellow?
, Aluminum chloride: colorless and transparent crystal or white and light yellow crystalline powder. 2, polyaluminium chloride: Polyaluminium Chloride, due to t
Polyaluminium chloride in the sewage plus there is no harm
Aluminum plays a role in sewage treatment polymerization, Baotuan, precipitation. Dosing less; dosing more, not only can not be aggregated, can not be aggregate
Alum and polyaluminium chloride which water purification effect alum dense
Less dosing, can reduce the cost of water treatment; corrosive, flocculation of alum to form faster, dense and heavy particles, which is conducive to pipeline p
PAC, PAM wastewater treatment principles
Non-ionic. PAM for flocculation, especially the dynamic potential, viscosity: PAM can effectively reduce the frictional resistance of the fluid, the water can b
Poly aluminum chloride will join 3 ~ 4% of the sodium chloride solution, no matter how low turbidity
The polyaluminum chloride should be aluminum chloride with crystal water, and the aluminum hydroxide produced by both is flocculent.

1, What are the abbreviations of PAC?
In morphology can be divided into two kinds of solid and liquid. Solid according to the different colors are divided into brown, beige, golden yellow and white,
Polyaluminium chloride how to detect
Polyaluminum chloride detection method: add acid in the sample depolymerization of the sample. Add an excess of ethylenediamine tetraethyl disodium solution wit
Whether the dosage of polyferric sulfate is higher the removal rate of COD is higher
