What is Poly Aluminium Chloride(PAC)?

Poly aluminium chloride (PAC) is a highly efficient and cheap inorganic high molecular compound. As flocculant, it’s mainly used for domestic sewage and industrial waste water treatment, such as textile and dyeing industrial, paper-making industrial, etc.

Polyaluminium Chloride Industrial Waste Water Grade represents a specialized formulation tailored for the exigencies of industrial effluent treatment. Recognized for its rapid coagulation kinetics and robust performance under challenging conditions, it effectively mitigates contaminants inherent in industrial wastewater streams.

Polyaluminium Chloride Drinking Grade conforms to stringent drinking water quality standards and is engineered to ensure the safety and potability of water supplies. Renowned for its non-toxic nature, superior solubility, and exceptional coagulation efficacy, it serves as a cornerstone in municipal water treatment infrastructure.

Polyaluminium Chloride White Powder represents a high-purity variant prized for its rapid dissolution kinetics and consistent coagulation performance. Characterized by its finely milled composition and exceptional solubility, it is favored for applications requiring precise dosage control and expedited coagulation processes.

How to use Poly Aluminium Chloride(PAC)?

Polyaluminum chloride (PAC) is a widely used coagulant in water treatment applications, particularly in the purification and clarification of water sources. The following are common uses for poly aluminum chloride (PAC):

  1. Dosage determination: Determine the optimal dose of PAC taking into account water quality parameters such as pH, turbidity, and pollutant concentration. Utilize the jar test method or seek guidance from a water treatment expert to determine precise dosage requirements.
  2. Solution preparation: PAC comes in many forms, including liquid, powder or flakes. If using solid PAC, prepare a solution by dissolving it in water according to the recommended dilution ratio and mixing scheme provided by the manufacturer.
  3. Application technology: Pre-dilution procedure: For solid PAC, pre-dilution is usually required to ensure even dispersion and efficient application. Follow pre-dilution guidelines before introducing PAC solution into the treatment process.
    Injection method: Use a metering pump or similar injection mechanism to introduce the PAC solution directly into the water stream. Carefully calibrate injection rates to achieve desired treatment goals.
    Mixing scheme: Thoroughly mix PAC-treated water in a dedicated mixing tank or utilizing a mechanical stirrer for optimal dispersion to facilitate the coagulation and flocculation process.
  1. Monitor and adjust: Implement a robust monitoring system to assess treatment effectiveness and make real-time adjustments as needed. Perform a comprehensive water quality analysis, measuring parameters such as turbidity, pH and residual PAC concentration.
  2. Safety Precautions: Prioritize safety protocols during PAC handling and application. Strictly follow the safety guidelines provided by the manufacturer, use appropriate personal protective equipment (PPE), and prevent direct skin or eye contact with PAC. Store PAC in designated areas away from incompatible materials in accordance with safety standards.
  3. Regulatory Compliance: Ensure compliance with local regulatory frameworks for use of PAC in water treatment processes. Maintain detailed records of PAC usage, treatment effectiveness, and any adjustments made to treatment regimens to facilitate regulatory compliance and audit preparation.

By employing these refined strategies and following best practices, PACs can be effectively deployed in water treatment operations to achieve optimal purification and clarification results.

The Most Common Applications of Polyaluminum chloride(PAC)

Polyaluminium chloride has a wide range of uses in the treatment of wastewater and drinking water. Some of its most common applications include:

Wastewater treatment: PAC is widely used in the treatment of industrial wastewater and urban sewage. It helps to coagulate and flocculate impurities such as suspended solids, colloids, and other organic and inorganic pollutants, causing them to settle out of the water.

Drinking water treatment: PAC is also used in drinking water treatment to remove impurities such as bacteria, viruses, algae and other microorganisms. It has been proven effective in removing a variety of contaminants from drinking water, including heavy metals, arsenic and fluoride.

Papermaking: PAC can be used as a sizing agent in papermaking to improve the strength and smoothness of paper.

Textile industry: PAC is used as a mordant or color-fixing agent in the textile industry to enhance the color fastness of fabrics.

Oil Drilling: PAC can be used as clay stabilizer and fluid loss reducer in oil drilling.

Other Industrial Applications: PAC is also used in a variety of other industrial applications, including the production of ceramics, cement, and paints.

Overall, polyaluminum chloride is a versatile and effective water treatment chemical with a wide range of applications across various industries. Its use helps ensure wastewater and drinking water are safe and free of harmful contaminants.

Differences between different colors of Poly Aluminum Chloride

  1. White Polyaluminium Chloride
    White PAC is typically the purest form of PAC available. It appears white or very light in color, indicating a high level of purity with minimal impurities. White PAC is often preferred for applications where color purity is critical, white PAC often has a neutral or slightly acidic pH.
    White PAC is widely used in drinking water treatment because it meets health and safety standards and is used in industrial processes where high purity standards must be maintained. White PAC can also be used in papermaking sizing agents, sugar decolorizing clarifiers, tanning, cosmetics, precision casting and other fields.
  2. Yellow Polyaluminium Chloride
    Yellow PAC usually results from the presence of iron impurities in the raw materials used during the manufacturing process. The presence of iron can give the PAC a yellowish tint. While yellow PAC is still effective as a coagulant, its color may be less desirable for applications where color purity is important.
    Yellow PAC has effective coagulation and flocculation properties, making it suitable for use in a variety of water treatment processes. Whether it is industrial water supply, industrial wastewater, industrial water circulation and urban sewage treatment, yellow PAC is the best choice.
  3. Light Yellow Polyaluminium Chloride
    Light yellow PAC is a variation that falls between white and yellow PAC in terms of color intensity. It may result from a lower concentration of iron impurities compared to standard yellow PAC. Light yellow PAC retains some of the characteristics of both white and yellow PAC, offering a balance between purity and color intensity. It can be suitable for applications where a slightly tinted coagulant is acceptable, but where high purity is still desired.
    Light yellow PAC offers a balance between purity and color intensity, making it suitable for applications where a slightly tinted coagulant is acceptable. It can be used in both potable water treatment and industrial applications.
  4. Brown Polyaluminium Chloride
    Brown PAC is another variation that may occur due to the presence of organic matter or other impurities in the raw materials. The brown color can indicate the presence of contaminants that may affect the efficacy of the PAC in water treatment processes. However, brown PAC can still be suitable for certain industrial applications where color purity is not critical.
    Brown PAC is often used in industrial water treatment processes where color purity is less critical. It can be effective in treating wastewater from industrial processes, including those with high organic content or complex contaminants.
