Product Description:
Polyaluminium Chloride (PAC), also known as basic aluminum chloride or coagulant, is a water-soluble inorganic polymer located between ALCl3 and AL(OH)3. Its chemical formula is [Al2(OH)nCl6-nLm], where "m" represents the degree of polymerization and "n" indicates the neutralization degree of the PAC product. It appears as a yellow, light yellow, dark brown, or dark gray resinous solid. This product has strong bridging and adsorption properties, and during hydrolysis, it undergoes physical and chemical processes such as coagulation, adsorption, and precipitation.
The fundamental difference between PAC and traditional inorganic coagulants is that traditional coagulants are low molecular crystalline salts, while PAC consists of a structure formed by variable carboxylate complexes. PAC has a fast flocculation and sedimentation speed, a wide applicable pH range, is non-corrosive to pipelines and equipment, and has a significant water purification effect. It can effectively remove color, SS, COD, BOD, and heavy metal ions such as arsenic and mercury from water. PAC is widely used in drinking water, industrial water, and wastewater treatment.
Product Performance:
Quickly forms large flocs with fast sedimentation, improving treatment capacity by 1.0-3.0 times compared to other inorganic coagulants.
Adapts to source water at various temperatures and dissolves well.
Low corrosiveness and easy to handle.
The liquid product is suitable for automated dosing and does not clog pipes with long-term use.
Usage Instructions:
The liquid product can be added directly or diluted with water before use. The solid product should be dissolved in water before dosing. The amount of water added depends on the dosage and the water quality to be treated. The dilution ratio is 2%-20% for solid products and 5%-50% for liquid products (by weight).
The dosage for liquid products is 3-40 grams per ton, and for solid products, it is 1-15 grams per ton. Users should determine the exact amount through stirring tests and production trials.
This product is less acidic than other inorganic coagulants.
