Poly Aluminium Chloride (PAC) is a highly effective coagulant, but its optimal performance and safety hinge on proper handling and storage. Whether you are using PAC in powder or liquid form, understanding the best practices is vital for maximizing its benefits and ensuring operational safety. As a reliable manufacturer and supplier of PAC, we provide essential guidance for industrial users looking to buy PAC and maintain its quality.

Handling Poly Aluminium Chloride (PAC)

PAC, in both its powder and liquid forms, requires careful handling to prevent degradation, contamination, and ensure user safety.

1. Powdered PAC:

  • Preparation of Solution: Powdered PAC is typically dissolved in water to create a solution before application. The concentration of the solution should be carefully determined based on the product's specifications and intended use. It is crucial to add the powder slowly to water with continuous stirring until fully dissolved. Avoid adding water to the powder, as this can lead to clumping and incomplete dissolution.
  • Dissolution Temperature: While PAC is soluble in water, using warm water (not boiling) can speed up the dissolution process. However, avoid prolonged heating, as it can affect product stability.
  • Solution Stability: Prepared PAC solutions are generally most effective when used within 24 hours. If stored for longer periods, their efficacy may decrease due to hydrolysis.
  • Personal Protective Equipment (PPE): When handling powdered PAC, wear appropriate PPE, including gloves, eye protection (goggles or face shield), and a dust mask or respirator, as PAC dust can be irritating to the respiratory tract and skin.

2. Liquid PAC:

  • Direct Dosing: Liquid PAC can often be dosed directly into the water system using calibrated dosing pumps. Ensure the dosing equipment is compatible with the chemical's properties.
  • Dilution (If Necessary): Some liquid PAC products may require dilution depending on the application and the dosing pump's capabilities. Follow the manufacturer's recommendations for dilution ratios and methods.
  • Material Compatibility: Ensure all handling equipment, pipes, and storage tanks are made of materials resistant to PAC, which can be mildly corrosive, especially at higher concentrations.

Storing Poly Aluminium Chloride (PAC)

Proper storage is key to maintaining the quality and shelf-life of PAC.

1. Powdered PAC:

  • Environment: Store in a cool, dry, well-ventilated area away from direct sunlight and sources of heat.
  • Packaging: Keep the original packaging sealed tightly to prevent moisture absorption, which can lead to caking and reduced efficacy. Store on pallets to avoid direct contact with the floor.
  • Segregation: Store PAC separately from incompatible materials to prevent hazardous reactions.

2. Liquid PAC:

  • Temperature: Store liquid PAC within the recommended temperature range to prevent freezing or excessive heating, which can degrade the product. Typically, storage below 50°C is advised.
  • Tanks: Use storage tanks made of compatible materials, such as HDPE or fiberglass-reinforced plastic (FRP). Avoid storing in mild steel or aluminum tanks.
  • Contamination: Ensure storage tanks are clean and protected from contamination.

Safety Considerations

Always refer to the Safety Data Sheet (SDS) provided by the manufacturer for detailed safety information. PAC can be irritating to skin, eyes, and the respiratory system. Proper ventilation and PPE are essential during handling.
