In the water treatment world, the benefits of PAC in water treatment continue to gain stronger recognition as industries seek more efficient, consistent, and cost-effective solutions. Poly Aluminium Chloride (PAC) has become one of the most widely used coagulants for raw water, process water, and wastewater treatment due to its superior performance and adaptability.
As clean water standards tighten and industrial water challenges become more complex, PAC offers a dependable foundation for achieving stable and high-quality results.
What Is PAC and Why Is It Essential in Water Treatment?
Poly Aluminium Chloride (PAC) is an inorganic polymer coagulant known for its high charge density, making it highly effective in destabilizing suspended particles, colloids, organic matter, and color in water. PAC is a preferred choice in water treatment facilities, manufacturing industries, municipal utilities, and various sectors because it delivers faster coagulation and clearer water using lower dosages compared to traditional coagulants like alum.
PAC is commonly applied in:
- Raw water treatment
- Drinking water purification
- Industrial process water treatment
- Wastewater treatment
- Clarification and filtration systems
- Food & beverage, palm oil, power plants, textile, pulp & paper, and many more
Its versatility and efficiency make PAC an essential and dependable component of modern water treatment operations.

What are the Benefits of PAC in Water Treatment?
Understanding the benefits of PAC in water treatment helps industries evaluate its suitability for their specific needs. Here are the core advantages that make PAC a superior coagulant:
1. Stronger and Faster Coagulation Performance
PAC has a higher charge neutralization capability compared to traditional coagulants. This allows suspended particles, organic substances, and colloids to aggregate more quickly and form denser flocs. As a result, the sedimentation or clarification process becomes more efficient.
2. Works Well Across a Wide pH Range
PAC performs effectively at a broader pH range (5–9), reducing the need for additional chemicals to adjust the pH. This is especially beneficial for raw water conditions that fluctuate significantly, such as river water during rainy seasons.
3. Lower Sludge Production
One of the most substantial benefits of PAC is its ability to create denser and more compact flocs, meaning less sludge is produced. Lower sludge volume reduces disposal costs, simplifies handling, and minimizes downtime.
4. Enhanced Water Clarity and Lower Turbidity
PAC consistently delivers low turbidity levels, even in challenging raw water sources such as high-TSS river water or peat water that contains high organic matter. Industries that rely on clear water for production will notice significant improvements.
5. Lower Dosage Requirements
With stronger coagulation properties, PAC often works effectively at lower dosages compared to aluminum sulfate or other traditional coagulants. This improves cost efficiency, reduces chemical consumption, and simplifies dosing operations.
6. Stable Performance Under Variable Conditions
Fluctuating raw water quality, especially during rainy seasons, can lead to unstable treatment performance. PAC remains effective even when turbidity, color, or organic matter levels change drastically, making it a reliable choice for facilities that face seasonal challenges.
7. Improved Filtration Efficiency
Because PAC forms stronger and more uniform flocs, downstream filtration systems benefit from reduced loading. This leads to longer filtration cycles, lower backwash frequency, and improved overall system performance.
