Liquid Poly Aluminum Chloride: The Preferred Choice for Efficient Water Treatment

In the field of water treatment, liquid poly aluminum chloride (PAC) is widely used as an efficient inorganic polymer coagulant for drinking water purification, industrial wastewater treatment, and municipal sewage treatment. Its unique chemical properties and high treatment efficiency make it one of the preferred materials in the water treatment industry.

1. What is Liquid Poly Aluminum Chloride?

Liquid poly aluminum chloride is an inorganic polymer compound with the chemical formula [Al2(OH)nCl6-n]m. It has high charge neutralization and adsorption bridging capabilities. Compared to solid PAC, the liquid form is easier to dissolve and dose, making operations more convenient.

2. Advantages of Liquid Poly Aluminum Chloride

• Efficient Coagulation: Liquid PAC quickly reacts with suspended solids, colloids, and heavy metal ions in water, forming large flocs that are easy to settle and filter.

• Strong Adaptability: Suitable for various water qualities, including low-temperature, low-turbidity water and high-turbidity water, with stable treatment effects.

• Easy Operation: The liquid form does not require dissolution and can be directly dosed, saving time and labor costs.

• Environmentally Friendly and Safe: Non-toxic and harmless, with low corrosiveness to equipment and pipelines, ensuring safe use.

3. Applications of Liquid Poly Aluminum Chloride

• Drinking Water Treatment: Removes suspended solids, colloids, and some heavy metals, ensuring compliance with national standards.

• Industrial Wastewater Treatment: Suitable for industries such as electroplating, printing, and papermaking, effectively removing harmful substances from wastewater.

• Municipal Sewage Treatment: Used for sludge dewatering and sewage purification, improving treatment efficiency and reducing operational costs.

• Swimming Pool Water Treatment: Removes suspended solids and colloids, maintaining clear water quality.

4. How to Choose the Right Liquid Poly Aluminum Chloride?

When selecting liquid PAC, consider the following factors:

• Water Quality Characteristics: Choose the appropriate PAC product based on the turbidity, pH, and types of pollutants in the raw water.

• Treatment Objectives: Define treatment goals, such as removing suspended solids, decolorization, or heavy metal removal, and select PAC with corresponding performance.

• Dosage: Determine the optimal dosage through experiments to achieve the best treatment effect and reduce costs.

• Supplier Qualifications: Choose qualified and reputable suppliers to ensure product quality and after-sales service.

5. How to Use Liquid Poly Aluminum Chloride

• Dosing Method: Liquid PAC can be directly dosed into raw water or precisely controlled using dosing equipment.

• Mixing Conditions: Ensure thorough mixing after dosing to allow PAC to fully react with pollutants in the water.

• Settling Time: Control the settling time based on water quality and treatment objectives to ensure complete floc settling.

6. Storage and Transportation of Liquid Poly Aluminum Chloride

• Storage Conditions: Store in a cool, ventilated place, avoiding direct sunlight and high temperatures.

• Packaging Specifications: Typically packaged in plastic drums or tankers for easy transportation and dosing.

• Shelf Life: The shelf life of liquid PAC is generally 6 months to 1 year, and it should be used within this period.

Conclusion

Liquid poly aluminum chloride, with its efficiency, convenience, and environmental friendliness, is an ideal choice for the water treatment industry. Through scientific selection and use, you can significantly improve water treatment efficiency, reduce operational costs, and achieve environmental goals.
