At City Chemicals, we supply premium-grade PAC 28% with strict adherence to international standards, ensuring safety, stability, and high customer satisfaction.

What is PAC 28%?

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant derived from aluminium salts. PAC 28% refers to the 28% basicity concentration, making it a highly effective water treatment agent. Unlike traditional coagulants such as alum, PAC 28% works at a wider pH range and produces less sludge, reducing disposal costs and improving sustainability.

How Does PAC 28% Work?

PAC 28% works through a process called coagulation and flocculation:

Coagulation – The positively charged aluminium ions neutralize negatively charged particles, bacteria, and organic matter in water.
Flocculation – Neutralized particles bind together, forming larger flocs that can be easily filtered or settled out.

This dual action results in clearer, safer, and cleaner water, suitable for both industrial and municipal applications.

Benefits of PAC 28%

Superior Efficiency: Works effectively across a broad pH range (4–10).
Reduced Sludge Production: Generates less waste compared to alum.
Fast Action: Rapid coagulation ensures quicker purification.
Cost Savings: Lower dosage requirement compared to conventional coagulants.
Versatility: Suitable for drinking water, wastewater, industrial effluents, and mining operations.
Long Shelf Life: Stable under proper storage conditions.

Safety & Handling

PAC 28% is safe to use when handled properly, but it should be stored and applied according to manufacturer guidelines. Always use protective equipment (gloves, goggles) when handling, and avoid inhalation or direct skin contact. In case of accidental contact, rinse thoroughly with water.

Longevity & Storage

Shelf Life: Up to 24 months when stored in sealed containers.
Storage Conditions: Store in a cool, dry, and well-ventilated area. Avoid direct sunlight and freezing temperatures.

Applications & Usage

PAC 28% is widely applied in:

Municipal Water Treatment: Ensures safe drinking water by removing turbidity, color, and bacteria.
Wastewater Treatment: Treats industrial and domestic wastewater efficiently.
Paper Industry: Improves paper sizing and retention.
Mining Operations: Assists in ore processing and tailing water treatment.
Textile Industry: Helps remove dyes and organic materials.

Dosage: Depends on water quality and application; typically ranges between 10–50 mg/L. Always consult technical guidelines for accurate dosing.
