Polyaluminum Chloride (PAC) is a highly efficient inorganic polymer coagulant widely used in water treatment and various industrial applications. Known for its superior performance compared to traditional coagulants like aluminum sulfate, PAC offers significant advantages in clarifying water and treating wastewater.

Chemically, PAC is represented by the general formula [Al2(OH)nCl6-n]m, where the degree of polymerization and basicity (n) varies depending on the specific product grade. This unique polymeric structure contributes to its excellent coagulation and flocculation capabilities across a wider pH range (typically 5.0-9.0) than traditional alternatives.

Our Polyaluminum Chloride is available in various grades to suit diverse needs, including technical grade and drinking water grade. The physical appearance often correlates with its purity and intended application. For instance, high-purity white powder is commonly used in sensitive applications such as the paper industry, pharmaceuticals, sugar refining, cosmetics, and daily chemical industries. A light yellow powder is typically designated for domestic drinking water treatment, ensuring the removal of turbidity, suspended solids, heavy metals, and colloidal particles to meet stringent purity standards. The yellow-brown powder, on the other hand, is primarily utilized for industrial wastewater, industrial circulating water, and urban sewage purification, effectively reducing COD, BOD, and phosphorus levels.

The mechanism of action involves PAC hydrolyzing in water to form positively charged polynuclear complexes, which neutralize the negative charges of suspended particles and colloidal matter. This neutralization leads to the formation of large, dense flocs that settle quickly or are easily filtered out. This results in significantly clearer treated water.

One of the key benefits of using PAC over traditional coagulants is the reduction in sludge volume generated during the treatment process, often by 30-50%. The flocs formed by PAC are also typically faster-forming and denser, leading to improved sedimentation and filtration efficiency. Furthermore, PAC tends to leave lower residual aluminum levels in the treated water, which is crucial for drinking water applications.

Beyond water treatment, PAC finds valuable uses in several industries. In paper manufacturing, it enhances fiber retention and improves drainage. The oil refining industry uses it to break oil-water emulsions. Food processing benefits from food-grade PAC for clarifying beverages like sugar juice and beer. Specialty applications include its use as an antiperspirant agent in cosmetics and as a hemostatic agent in pharmaceuticals. It can even be used in construction to accelerate concrete setting.

Our product, available as a yellow granular powder with an Al2O3 content typically ranging from 26% to 30%, adheres to strict quality standards. It is packaged in durable 25KG PP bags for convenient handling and storage, requiring a dry and cool place. We ensure robust quality control throughout the production and packaging process, maintaining product stability and integrity.
