Poly Aluminium Chloride (PAC) is a sophisticated inorganic polymer coagulant that has revolutionized water treatment processes. Its efficacy stems from its unique chemical structure and the advanced manufacturing methods employed to produce it. As a leading manufacturer and supplier, we understand the intricacies of PAC production and its impact on performance.

At its core, PAC is a complex inorganic polymer formed by the controlled hydrolysis and polymerization of aluminum chloride. The general chemical formula often represented as [Aln(OH)mCl(3n-m)]x signifies a chain of aluminum atoms linked by hydroxyl groups and chloride ions. The degree of hydrolysis, determined by the ratio of hydroxyl to aluminum ions (basicity), significantly influences PAC's properties and performance. Higher basicity generally leads to a more cationic charge and greater coagulating power.

Production methods for PAC typically involve reacting aluminum-containing raw materials, such as aluminum hydroxide or bauxite, with hydrochloric acid under controlled conditions. Different production techniques, including spray drying, roller drying, and plate-and-frame filtration, result in various physical forms (powder or liquid) and grades of PAC. For instance, spray drying often yields a white or light yellow powder with high purity, while roller drying might produce yellow or brown powder, often utilized in industrial wastewater treatment where color is less critical.

Key properties that make PAC a superior coagulant include:

• High Cationic Charge: The abundant hydroxyl groups create positively charged polymeric species that effectively neutralize negatively charged colloids and suspended solids in water.
• Broad pH Range: PAC remains effective across a wider pH spectrum than traditional coagulants, simplifying treatment and reducing the need for pH adjustment chemicals.
• Rapid Flocculation: It promotes the rapid formation of large, dense flocs, leading to efficient sedimentation and improved filtration rates.
• Lower Dosage: PAC's high efficiency means lower chemical doses are required, resulting in cost savings and reduced sludge generation.
• Stable Performance: PAC exhibits good stability, allowing for effective performance even in low temperatures and varying water conditions.
