Description
Polyaluminium Chloride PAC, also known as polyaluminium chloride, is a highly efficient inorganic polymer coagulant, widely used in water treatment, sewage treatment, and industrial wastewater treatment. The main components of our product are aluminum ions (Al³⁺) and chloride ions (Cl⁻), which have strong flocculation properties and can effectively remove suspended matter, heavy metal ions, and other pollutants in water.
Advantages
High-efficiency water purification performance
Polyaluminium Chloride PAC has significantly better water purification performance as a coagulant than traditional water purifiers. Our products can quickly break the stability of colloidal particles in sewage through multiple mechanisms such as electrical neutralization, bridging adsorption, and sweeping sedimentation so that small particles of colloidal flocculation become larger and settle. This process is not only fast, but also highly efficient.
Wide applicability
Our products have an extensive range of applicability, with a pH range of 5.0-9.0, which means that PAC can treat sewage of various properties. In addition, our coagulant is also highly adaptable to water temperature and can maintain a stable precipitation effect even under low-temperature conditions.
Excellent stability
Our products are high-molecular polymers formed by the reaction of aluminum salts and chlorides. They have a high molecular weight and strong cohesion, which enables them to react quickly and stably with pollutants in water and form precipitation during water treatment. In water with a pH of 6.0, our products can achieve a COD removal rate of more than 85%, while the removal rate of traditional aluminum salt flocculants is usually less than 70%.
Applications
Drinking water treatment
The main role of our products in drinking water treatment is to remove suspended matter, chromaticity, heavy metals and organic pollutants in water.
Urban sewage treatment
In the process of urban sewage treatment, it is mainly used to remove suspended matter, grease, bacteria and other pollutants in water. Our products can quickly react with pollutants to generate large particles that can settle, thereby improving the efficiency of sewage treatment.
Papermaking industry
Our products are widely used as pulp additives in the papermaking industry. Their main role is to increase the solid content in pulp and improve the strength and quality of paper.

FAQ
Q: How does Polyaluminium Chloride (PAC) work in water treatment?
A: PAC works by neutralizing the charge on suspended particles in water. The positive charge of PAC attracts the negatively charged particles, causing them to clump together (coagulate). These larger clumps can then be easily removed through sedimentation or filtration.
Q: What are the main applications of Polyaluminium Chloride (PAC)?
A: PAC is commonly used in water treatment for municipal drinking water purification, wastewater treatment, industrial effluent treatment, paper and pulp processing, and textile industries. It is also used in the production of cosmetics and as a flocculant in certain food and beverage processes.
Q: Is Polyaluminium Chloride (PAC) safe to use in drinking water?
A: Yes, when used in proper concentrations, PAC is safe for use in drinking water treatment. It is approved by various regulatory bodies, such as the U.S. Environmental Protection Agency (EPA), as a safe coagulant. However, overuse can lead to residual aluminum in the water, which should be monitored.
Q: How is Polyaluminium Chloride (PAC) different from aluminum sulfate (alum)?
A: PAC is a more advanced form of aluminum coagulant than alum (aluminum sulfate). PAC has a higher charge density, making it more effective at lower doses and in a broader pH range. PAC also produces less sludge compared to alum, making it a more efficient choice in many applications.
Q: What is the typical dosage of Polyaluminium Chloride (PAC) in water treatment?
A: The dosage of PAC varies depending on the water quality, turbidity, and the specific treatment requirements. Typically, PAC is used in the range of 1 to 50 mg/L in drinking water treatment. However, the exact dosage should be determined through jar testing to optimize the treatment process.
Q: Can Polyaluminium Chloride (PAC) be used for wastewater treatment?
A: Yes, PAC is highly effective in wastewater treatment. It is used to treat municipal and industrial wastewater, helping to remove suspended solids, oils, fats, and organic compounds. PAC is particularly useful in situations where high-quality effluent is required.
Q: What are the environmental impacts of using Polyaluminium Chloride (PAC)?
A: PAC is generally considered to have a lower environmental impact compared to other coagulants, like aluminum sulfate. It produces less sludge and is more efficient, reducing the amount of chemical waste. However, care must be taken to monitor aluminum levels in treated water, as excessive aluminum concentrations can be harmful to aquatic life.
Q: What safety precautions should be taken when handling Polyaluminium Chloride (PAC)?
A: When handling PAC, it is important to follow proper safety protocols. PAC is typically a low-toxicity substance, but it can cause skin and eye irritation. Personal protective equipment (PPE) such as gloves, goggles, and dust masks should be worn to avoid contact with the chemical. Proper storage should be in a cool, dry place to prevent degradation.
