Short on time? Let Poly Aluminium Chloride sellers contact you.
Polyaluminium chloride (PAC) is high-efficient, cheap and nontoxic inorganic high molecular compound. It's easily soluble in water. In the hydrolytic process, it is accompanied with the chemical processes such as electrochemistry, coagulation, absorption and precipitation. The product has the features including wide applicable range of PH value, large granule and quick speed in sedimentation. It's widely used in treating the domestic drinking water, domestic sewage and industrial wastewater.
Application
1. City water supply and drainage purification, such as river, reservoir water and groundwater.
2. Industrial water purification.
3. City sewage treatment.
4. Useful material recovery in industrial waste water and waste residue; promote the settlement of pulverized coal in coal washing waste water; recovery of starch in manufacture process.
5. All kinds of industrial waste water treatment, such as dyeing waste water, leather fluoride waste water, heavy metal waste water, oily waste water, paper making waste water, waste water treatment, mining waste water, brewing waste water, metallurgical waste water and meat processing waste water etc.
6. Waste water treatment.
7. Paper-making sizing, sugar refining, casting, medicine refining, cement quick setting and cosmetics raw materials etc.

How to Use PAC Powder 30% in Water Treatment
The way of PAC powder 30% phase is simple to remember. Dilute PAC into a 5-10% solution with clean water and add it to the water source to be treated with the following dosages:
- The dosage for 1m3 of river, pond, and lake water:
+ For water with low turbidity: 1- 4g/m3 PAC
+ For water with medium turbidity: 5 - 7g/m3 PAC
+ For water with high turbidity: 7 - 10g/m3 PAC
- The dosage of wastewater treatment (making paper, textile, dyeing, food processing) from 20-200g/m3, depending on the suspended matter content and the wastewater characteristics.
PAC (Poly aluminium Chloride) referred to as PAC. Usually referred to as Basic or a coagulant such as aluminum chloride, which is between ALCL3 and AL (OH) 3 between a water-soluble inorganic polymers, chemistry the general formula: [Al2(OH)n Cl6-n]m where m on behalf of polymerization degree, n said that the neutral level of PAC products. The color yellow or light yellow, dark brown, dark gray resin-like solid. The product has a strong bridge adsorption performance, during the hydrolysis process, accompanied by cohesion occurs, adsorption and precipitation and other physical chemical processes
We provide Poly Aluminium Chloride (PAC) in both Liquid and Powder Form. This product is used as a flocculent and coagulant in Water Purification, for Treatment of Drinking / potable water, Waste-Water treatment and in Paper Industry for Sizing process.
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.
Molecular formula Al2Cl(OH)5
CAS No.: 1327-41-9
Polyaluminium chlorides are synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs.The flocs absorb suspended pollutants in the water which are precipitated with the PAC and can together be easily removed.
Polyaluminium chloride (PAC) is increasingly used for water treatment. Against the conventional use of aluminium sulphate (alum) it is showing distinct advantages.PAC can be used as a flocculant for all types of water treatment treatment, drinking water, industrial waste water, urban waste water and in the paper industry.
