High-Performance Coagulant for Water & Wastewater Treatment Applications

Polyaluminum Chloride (PAC) is an advanced inorganic polymer coagulant widely used in drinking water treatment, wastewater treatment, industrial effluent processing, and municipal water purification systems. Known for its strong coagulation efficiency, fast settling properties, and broad pH applicability, PAC has become one of the most preferred water treatment chemicals worldwide.

Compared to traditional coagulants such as aluminum sulfate (alum), PAC offers higher performance at lower dosage, produces less sludge, and delivers more stable water quality results, making it suitable for both small-scale and large-scale treatment facilities.

What is Polyaluminum Chloride (PAC)?

Polyaluminum Chloride is a pre-hydrolyzed aluminum salt, formulated by partially neutralizing aluminum chloride. This process results in a polymerized aluminum compound with enhanced charge density and coagulation power.

PAC is available in liquid and powder forms, and in various grades depending on aluminum oxide (Al₂O₃) content, basicity, and application requirements. Its chemical structure allows it to rapidly neutralize suspended particles and colloids in water, forming dense flocs that settle quickly and are easily removed.

Key Applications of PAC

1. Drinking Water Treatment

PAC is extensively used in municipal and industrial potable water treatment plants to remove:

• Turbidity

• Suspended solids

• Organic matter

• Color and odor

It provides clear water with improved filtration performance and reduced residual aluminum.

2. Wastewater & Sewage Treatment

In municipal wastewater treatment, PAC is used for:

• Primary and secondary treatment

• Phosphorus removal

• Sludge dewatering improvement

It is also effective in treating industrial wastewater from textile, paper, dyeing, food processing, and chemical industries.

3. Industrial Effluent Treatment

PAC is widely applied in treating high-load industrial effluents, including:

• Textile wastewater

• Paper & pulp effluent

• Oil & grease removal

• Heavy metal reduction

Its strong coagulating ability ensures consistent performance even in challenging water conditions.

4. Other Industrial Uses

PAC is also used in:

• Swimming pool water treatment

• Oilfield water treatment

• Pre-treatment for reverse osmosis (RO) systems

Key Benefits of Polyaluminum Chloride

• High coagulation and flocculation efficiency

• Faster settling and clarification

• Effective across a wide pH range

• Lower dosage requirement compared to alum

• Reduced sludge volume and disposal cost

• Improved water clarity and color removal

• Suitable for cold and low-turbidity water

• Stable performance in varying water conditions

These advantages make PAC a cost-effective and reliable solution for modern water treatment systems.
