What is Poly Aluminium Chloride?
Poly aluminium chloride (PAC) is an inorganic polymer coagulant that is widely used in water treatment processes. It is composed of aluminum salts, primarily aluminum chloride, and various hydroxide species. PAC is effective in removing suspended particles, organic matter, and certain dissolved substances from water by coagulating them into larger flocs, which can then be easily separated. It is commonly used in municipal water treatment, industrial water treatment, wastewater treatment, and other applications where effective coagulation and flocculation are required.
Poly Aluminium Chloride Uses
Water Treatment: PAC is widely used in water treatment processes to clarify and purify water. It effectively removes suspended particles, turbidity, and colloidal matter, improving the overall quality of the water.
Wastewater Treatment: PAC is employed in wastewater treatment plants to aid in the coagulation and flocculation of contaminants, allowing for their easy removal. It helps in the removal of pollutants, organic matter, and heavy metals from industrial and municipal wastewater.
Drinking Water Treatment: PAC is utilized in the treatment of drinking water to ensure its safety and compliance with regulatory standards. It assists in the removal of impurities, including bacteria, viruses, and organic compounds.
Paper and Pulp Industry: PAC is used in the paper and pulp industry as a retention aid and filler fixing agent. It improves the retention of fibers and fillers, resulting in enhanced paper quality and increased production efficiency.
Textile and Dyeing Industry: PAC finds application in the textile and dyeing industry for color removal and wastewater treatment. It aids in the removal of dyes and organic contaminants from textile effluents.
Poly Aluminium Chloride Properties
Physical State: PAC is typically available as a yellowish to brownish powder or in the form of a pale yellow liquid solution.
Solubility: It is highly soluble in water, forming a clear solution.
Coagulation Efficiency: PAC has high coagulation efficiency and is effective in removing suspended particles, colloidal matter, and organic substances from water.
pH Stability: PAC is stable over a wide pH range, which allows for its effective use in various water treatment conditions.
Hydrolysis: It undergoes hydrolysis when dissolved in water, forming aluminum hydroxide flocs that aid in the coagulation process.
Flocculation: PAC promotes the flocculation of impurities, facilitating their removal by settling or filtration.
Poly Aluminium Chloride Manufacturing Process
Raw Materials Preparation: Aluminum hydroxide or aluminum oxide and hydrochloric acid are prepared as the main raw materials.
Reaction: The raw materials are reacted together, resulting in the formation of polymeric aluminum species.
Polymerization: The reaction mixture undergoes polymerization to enhance the coagulation efficiency of PAC.
Aging and Maturation: The mixture is allowed to age and mature, which improves the performance of PAC.
Neutralization and Adjustment: The pH of the mixture is adjusted to the desired range using a base.
Filtration and Drying: The PAC solution is filtered to remove impurities, and it can be dried to obtain a powdered form.
Packaging and Storage: The final PAC product is packaged and stored appropriately for distribution and use.
The price of Poly Aluminium Chloride (PAC) can vary depending on various factors such as the region, purity, quantity, supplier, and market conditions. Additionally, prices can fluctuate over time due to changes in raw material costs and supply-demand dynamics. Therefore, it’s challenging to provide an exact price without specific details.
poly aluminium chloride is packaged in 25Kg/Bag, two layers bag, inner is plastic pp bag, outside is wooven bag
The chemical formula for Poly Aluminium Chloride (PAC) is typically represented as [Al2(OH)nCl6-n]m, where “n” represents the degree of polymerization and can vary, and “m” represents the charge neutrality of the compound. The exact values of “n” and “m” can differ depending on the specific product and manufacturing process used to produce PAC.
