Key Applications of Polyaluminium Chloride

Polyaluminium chloride (PAC) serves several crucial roles across different sectors. Its primary applications include:

Water Treatment

• Drinking Water Purification: PAC is frequently used in the treatment of drinking water due to its efficiency in removing particulates and impurities.
• Wastewater Treatment: It effectively coagulates and flocculates suspended solids in wastewater, aiding in the purification process before discharge.

Paper and Pulp Industry

• Papermaking: In the paper industry, PAC is used as a retention and drainage aid, enhancing the quality of paper and reducing production costs.

Textile Industry

• Dye Fixation: PAC helps in fixing dyes to fabrics, improving color fastness and reducing environmental impact from dye runoff.

Food and Beverage Industry

• Clarification Agent: In the food sector, polyaluminium chloride is employed for clarifying juices and beverages, ensuring product purity and safety.

Variants of Polyaluminium Chloride

Liquid vs. Powdered Form

Polyaluminium chloride is available in both liquid and powdered forms, each with distinct benefits:

• Liquid PAC:

  • Easier to implement in automated dosing systems.
  • Generally more effective in reducing turbidity in water treatment.

• Powdered PAC:

  • Longer shelf life and easier to transport.
  • Often more cost-effective for large-scale operations.

Basicity Levels

Polyaluminium chloride comes in varying basicity levels, which affect its effectiveness in different applications:

• High Basicity: Ideal for drinking water treatment and applications requiring rapid coagulation.
• Low Basicity: Preferred for wastewater treatment, as they form less sludge and are more environmentally friendly.

Buyer Considerations for Polyaluminium Chloride

When sourcing polyaluminium chloride, there are several key factors to consider:

Quality Standards

• Ensure the PAC meets local and international quality standards, especially for applications in drinking water and food.
• Look for certifications such as NSF/ANSI, ISO 9001, or similar to guarantee product safety and efficacy.

Manufacturer Reputation

• Choose suppliers with a proven track record in the industry.
• Research customer reviews and testimonials to gauge the reliability and service quality of the manufacturer.

Pricing and Cost-effectiveness

• Compare prices from multiple suppliers but prioritize quality over cost.
• Consider bulk purchasing options to reduce overall procurement expenses.

Technical Support and Documentation

• Ensure suppliers provide comprehensive technical data sheets and safety data sheets for handling and storage.
• Look for suppliers who can offer technical assistance for optimizing PAC usage in specific applications.

Common Questions and Practical Suggestions

What happens if polyaluminium chloride is over-dosed?

Over-dosing can lead to excessive sludge formation and difficulty in filtration. To avoid this:

• Conduct jar tests to determine optimal dosage levels before large-scale application.

How should polyaluminium chloride be stored?

Store PAC in a cool, dry place away from direct sunlight.

• Always keep it sealed to prevent contamination.

Can polyaluminium chloride be used in cold water conditions?

Yes, PAC is effective even in cold water conditions. However, flocculation times may need adjustment.

• Carry out preliminary tests to establish the optimal contact time.
