Applications of PAC in wastewater treatment

PAC is a chemical widely used in daily life, especially in wastewater treatment. So what is PAC 10% liquid? Is it safe for wastewater treatment? Let’s explore this topic with Loc Thien Chemicals today.

What is PAC 10% liquid?

Its general chemical formula is: [Al2(OH)nCl6-n]m. Here, n and m can vary depending on specific conditions.

PAC usually exists in powder or aqueous solution form, and it has the ability to create fine sediment when added to water that needs treatment.

Among them, PAC 10% liquid is a Poly Aluminium Chloride solution with a concentration of 10%. This means that in the solution, 10% is PAC and the rest is water or carriers. Specifically, if you have 1 liter of PAC 10% solution, it contains 0.1 liters of PAC and 0.9 liters of water or other carriers.

Advantages of PAC 10% liquid:

• The liquid form of PAC 10% often has high sedimentation efficiency, enhancing the process of sediment formation and precipitation. This can lead to reduced sedimentation time and improved removal of impurities in water.
• Fast coagulation time, making the water treatment process efficient and quick.
• Using liquid PAC can increase water clarity, reduce turbidity, and improve water quality after treatment.
• Liquid PAC can reduce the need for coagulants, lowering costs and simplifying the treatment process.
• Minimal impact on water pH, helping to maintain a stable water environment.
• PAC 10% liquid can effectively remove both soluble and insoluble organic matter and heavy metals, improving treated water quality.
• Reduces the volume of sludge generated during water treatment.
• Effective at low dosages, reducing costs and enhancing sediment settling.
• Minimizes corrosion of equipment in water treatment systems, reducing maintenance and repair costs.
• Operates effectively across a wide pH range from 5 to 8.5, corresponding to the typical pH range in treated water.

Poly aluminium chloride | PAC 10% liquid

Benefits of liquid PAC:

• Liquid PAC effectively removes impurities:
  • PAC is a coagulant that can remove impurities from water, making it safe for drinking and various uses. Additionally, this chemical is highly effective in removing suspended solids, organic matter, and color from water.
• Poly Aluminium Chloride is cost-effective:
  • Poly Aluminium Chloride is a solution that optimizes costs for water treatment processes. Even a small amount can achieve high efficiency, making it a cost-effective choice compared to other coagulants.
• Poly Aluminium Chloride is safe and non-toxic:
  • This benefit relates to the safety and non-toxicity of using liquid PAC in water treatment processes. It does not harm human health or pose any risks to the environment.
• Liquid PAC is easy to use:
  • Liquid PAC is easy to use and dissolves quickly in water. This makes it convenient to add directly to water and dissolve rapidly in treatment processes.
• PAC has a long shelf life:
  • Liquid PAC can be stored under appropriate conditions without losing its effectiveness. This makes it a cost-effective and convenient solution for water treatment processes.
• Compliance with safety and environmental standards:
  • PAC complies with safety and environmental standards during use. This ensures that the water treatment process is not only effective but also meets safety and environmental protection requirements.

Procedure for preparing liquid PAC for wastewater treatment:

• Step 1: Prepare materials and tools:
  • Prepare PAC solution and clean water.
• Step 2: Determine the required PAC dosage:
  • Based on the type of water to be treated and treatment goals, determine the required PAC dosage. This dosage is usually measured in ppm (parts per million) or kg/1000 m³ of water.
  • Use measuring tools to determine the required PAC amount based on the dosage.
• Step 3: Mix PAC with water evenly:
  • Use appropriate tools to add Poly Aluminium Chloride to water. Add slowly and gently to avoid clogging and foaming.
  • Stir the mixture well to ensure the solution dissolves and distributes evenly in the water.
• Step 4: Proceed with wastewater treatment using PAC:
  • Use mixing tools such as stirrers to ensure PAC is evenly distributed in the water.
  • Mix until liquid PAC is completely dissolved in water and the mixture becomes uniform.
• Step 5: Check pH and adjust:
  • Check the pH of the mixture to ensure it is within the suitable range for water treatment.
  • Adjust pH if necessary by adding pH adjusters.

Proper storage of liquid PAC:

• Store in a cool place, away from direct sunlight and high temperatures.
• Do not freeze PAC 10% liquid, as it can alter its chemical structure and prevent high temperatures.
• Store liquid PAC in tightly sealed tanks or containers to prevent exposure to air.
• Avoid contact with metals, especially those that can corrode or react with PAC.
• Avoid mixing PAC 10% liquid with other substances that may affect its properties.
• Conduct regular quality checks to ensure liquid PAC meets the required standards for your specific application.

Precautions when using Poly Aluminium Chloride (PAC):

• Always wear personal protective equipment such as gloves, goggles, chemical-resistant clothing, and safety shoes when working.
