Poly aluminium Chloride (PAC): Uses and Specifications
Poly aluminium Chloride, commonly known as PAC, is a highly effective inorganic polymer coagulant widely used in water purification and wastewater treatment industries. It is recognized for its excellent coagulation performance, rapid sedimentation capability, and cost-effective operation compared to traditional alum chemicals.
PAC is available in liquid and powder forms and is extensively used in municipal water treatment plants, industrial effluent processing, textile industries, paper manufacturing, and swimming pool water treatment.

Uses of Poly aluminium Chloride
1. Drinking Water Treatment
PAC is widely used for purifying drinking water by removing suspended particles, bacteria, and organic impurities. It helps improve water clarity and reduces turbidity effectively.
2. Wastewater Treatment
Industries use PAC for treating industrial wastewater and sewage water. It removes heavy metals, oil particles, phosphates, and harmful contaminants from wastewater.
3. Textile Industry
In textile manufacturing, PAC is used for color removal and dye wastewater treatment. It enhances sedimentation and reduces chemical oxygen demand (COD).
4. Paper Industry
PAC acts as a retention agent and sizing promoter in paper production. It improves paper quality and reduces production costs.
5. Swimming Pool Water Purification
PAC helps maintain clean and safe swimming pool water by removing fine particles and impurities quickly.
6. Oil & Gas Industry
PAC is used in oil refining and drilling wastewater treatment processes to separate suspended solids and oily substances.
7. Sugar and Food Processing
Food and sugar industries use PAC for clarification and purification during processing operations.
Advantages of Poly aluminium Chloride
