What is the chemical PAC used for?
Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency, and it has the widest pH and temperature application ranges compared to other water treatment chemicals.

What is the use of PAC in the paper industry?
Polyaluminium chloride (PAC) can be applied in paper making. In the paper industry, PAC is often used as a coagulant in the papermaking process. It helps to remove impurities and suspended particles from the pulp, which results in a clearer and cleaner paper product.
How does PAC remove contaminants from water?
The adsorption process is what makes PAC effective. When water passes through a PAC system, contaminants stick to the activated carbon. This removes them from the water.

Benefits
- Polyaluminum chloride, also known as PAC poly aluminum chloride, offers superior purifying effects, especially on low-temperature, low-turbidity, and heavily organic-polluted raw water-performing significantly better than other organic flocculants. Moreover, it can reduce treatment costs by 20% to 80%.
- It promotes the rapid formation of large flocculants (particularly at low temperatures), ensuring fast sedimentation and extending the service life of the cellular filter in the sedimentation basin.
- Polyaluminum chloride water treatment is effective across a wide pH range (5–9), and it can slightly reduce the pH value and basicity of the treated water. Compared with traditional flocculants, the required dosage is lower, making it more economical and efficient.
- The product shows strong adaptability to various water qualities in different regions and under different temperatures. Thanks to its higher basicity, lower corrosiveness, and ease of operation, poly aluminum chloride is ideal for long-term use without causing filter blockages.
- The polyaluminum chloride solution forms further simplifies handling and dosing, making it a preferred choice in many industrial and municipal water treatment systems.
