Category: PAC powder

PAC (Poly Aluminum Chloride) 30% - 31% is a chemical specially designed to optimize the coagulation and sedimentation process in water supply and wastewater treatment. With lemon yellow or white powderPAC is not only highly effective in removing impurities, bacteria, and suspended solids but also has little effect on the pH of the water.

PAC outperforms traditional coagulants such as alum in its ability to effectively remove dissolved organic matter, heavy metals, and reduce sludge production. It is an ideal solution for domestic, industrial, and wastewater treatment plants with high turbidity.

• Urban water treatment: Improve water quality, increase clarity and reduce turbidity before distribution.

PAC powder 30% - 31% is not only suitable for large water treatment systems but also the optimal choice for industries requiring high treatment quality.

Instructions for using PAC 30% – 31%

1. Solution preparation:
   • Mix PAC powder into a 5% - 10% solution in clean water.
   • Stir well to dissolve completely before adding to the water source to be treated.
2. Recommended dosage:
   • Water supply: 1 – 10 g/m³ depending on water turbidity.
   • Wastewater: 20 – 200 g/m³ depending on the amount of suspended solids and the nature of the wastewater.
3. Processing procedure:
   • Add PAC solution to water source, stir well to create floc.
   • Let the floc settle, then decant or filter to remove impurities.

Note: Experimentation is required to determine the appropriate dosage for each specific type of water, ensuring maximum effectiveness.

FAQ – Frequently Asked Questions about PAC 30 31

• Is PAC 30% - 31% suitable for well water treatment?
  • Yes, PAC 30% – 31% is very suitable for treating well water thanks to its ability to coagulate suspended impurities, remove heavy metals such as iron, manganese, and quickly clarify water. However, the pH of well water is often low, so it is necessary to check and adjust the pH before using PAC to achieve optimal efficiency.
• How to determine the appropriate PAC dosage for each type of water?
  • PAC dosage is not fixed but depends on turbidity, concentration of organic matter, heavy metals in water. To determine accurately:
    • Prepare PAC solution (5% – 10%) and experiment with different dosage levels.
    • Observe the floc formation process: If the floc is large and settles quickly → appropriate dosage.
    • If the water is still cloudy or the floc is small → Need to increase/decrease the dosage of PAC.
  • 📌 Suggestion:
    • Water supply: 1 – 10 g/m³
    • Industrial wastewater: 20 – 200 g/m³
• What is the difference between lemon yellow powder PAC and white powder PAC?
  • PAC powder has two main types with different characteristics:
    • Lemon yellow PAC (popular type): Contains higher aluminum content, stronger coagulation effect, suitable for treating high turbidity industrial wastewater.
    • White PAC (purer type): Contains lower aluminum content, fewer impurities, suitable for treating domestic water, drinking water, where higher quality is required.
    • 📌 Choosing the right PAC for each system will help optimize water treatment efficiency and save costs.
• Does PAC 30% – 31% affect piping systems and equipment?
  • No, PAC does not corrode equipment and pipes like alum because:
  • Does not generate corrosive sulfate ions (SO₄²⁻), providing long-term system protection.
  • Does not suddenly reduce pH, limiting negative impacts on equipment.
  • Reduce sludge volume, helping the water treatment system operate more stably.
    • ✅ PAC is safe for industrial and civil water treatment systems, helping to prolong equipment life.
• How to properly preserve PAC 30% - 31% to extend its shelf life?
  • To keep PAC 30% - 31% stable and highly effective, the following preservation principles must be followed:
    • Store in a cool, dry place, away from direct sunlight.
    • Avoid high humidity, because PAC has strong hygroscopic properties and can easily clump if not properly preserved.
    • Close packaging after use, limit exposure to air to avoid quality loss.
    • Ideal storage time: 12 – 24 months if stored properly.
  • 📌 Note: If PAC is slightly lumpy, it can be stirred well when mixing the solution for normal use. However, if PAC shows signs of decomposition or loss of coagulant effect, it should be replaced with a new batch.
