High Efficiency PAC for Water Treatment

White Polyaluminum Chloride (PAC) is classified as an inorganic polymer coagulant and a promising substance for water purification. Essentially, it is an inorganic polymer that dissolves in water and falls between the compounds AlCl ∝ and Al (OH) ∝. Its chemical formula is [Al2 (OH) nCl6-n] m, where m indicates the polymerization level and n represents the neutrality of the product.

Features:

High water purification effect: With a high content of Al₂O₃, it has a strong adsorption and coagulation effect on suspended solids, colloidal impurities, etc. in water, and can effectively remove COD, BOD, arsenic, mercury and other heavy metal ions from water. It can reduce the turbidity of high turbidity water, and the purified water quality is better than ordinary coagulants such as Aluminum Sulfate.

Good stability: It has the advantages of good spray drying stability, wide adaptability to water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, dense quality, fast sedimentation speed, low effluent turbidity, and good dehydration performance.

Non corrosive: The aqueous solution is clear and colorless, non corrosive to pipeline equipment, does not introduce harmful ions, and is safe and reliable to use.

Widely applicable pH range: It can effectively exert coagulation effect within a wide pH range, without the need for a large adjustment of the pH value of the raw water, and can meet the purification needs of general raw water.

Easy formation of flocs: easily hydrolyzed in water, forming various forms of Al (OH) m+ions, which undergo electrical neutralization and adsorption bridging with impurity particles in water, causing colloidal particles to destabilize and flocculate. The formed flocs have a certain strength, are not easily broken, and have good precipitation performance.

Applications:

Drinking water treatment plays a critical role in removing suspended solids, colloidal impurities, microorganisms, and other pollutants in water to ensure that the water quality meets the standards for domestic drinking water. This process is commonly employed in urban water plants, rural drinking water treatment projects, and various other applications.

Industrial water treatment, on the other hand, is essential for industries such as power, chemical, textile, and paper industries. It aims to purify industrial water, enhance water quality to meet production process requirements, and reduce the likelihood of equipment corrosion and scaling during manufacturing.
