The textile industry is notorious for its complex wastewater streams, often laden with residual dyes, high organic loads (measured by COD - Chemical Oxygen Demand), and various finishing chemicals. Treating this effluent effectively is a significant challenge, essential for environmental compliance and sustainable manufacturing. Polyaluminium Chloride (PAC) has emerged as a powerful and cost-effective coagulant for tackling these issues. As a leading PAC manufacturer and supplier, we understand the unique requirements of the textile sector and offer solutions designed for optimal performance.

How PAC Addresses Textile Wastewater Challenges

Textile wastewater is characterized by:

  • High Color Intensity: Dyes used in textile processing are often recalcitrant and impart significant color to the wastewater, which is aesthetically undesirable and can impede light penetration in receiving waters.
  • High Chemical Oxygen Demand (COD): Organic compounds from dyes, auxiliaries, and sizing agents contribute to a high COD, indicating a significant oxygen demand in the receiving water body if discharged untreated.
  • Suspended Solids and Turbidity: Fibers, fillers, and precipitated chemicals can increase suspended solids and turbidity.

PAC works by efficiently coagulating and flocculating these pollutants:

  • Dye Removal: The positively charged polymeric species in PAC are highly effective at adsorbing and destabilizing the anionic dye molecules, causing them to aggregate and precipitate out of the water. This significantly reduces the color of the effluent.
  • COD Reduction: PAC helps to aggregate dissolved organic matter, including many COD-causing compounds, making them amenable to removal through sedimentation or filtration.
  • Suspended Solids Removal: Like in other water treatment applications, PAC efficiently removes suspended solids, reducing turbidity.

Advantages of Using PAC in Textile Effluent Treatment

  • Superior Color and COD Removal: PAC often outperforms traditional coagulants like alum or ferric chloride in removing color and reducing COD, especially with reactive and direct dyes.
  • Cost-Effectiveness: The high efficiency of PAC allows for lower dosage rates, leading to reduced chemical costs, especially when purchased in bulk from a reliable manufacturer.
  • Improved Sludge Characteristics: PAC typically produces denser, more compact flocs, which can lead to reduced sludge volumes and easier dewatering compared to alum.
  • Adaptability: PAC is effective over a broad pH range and can handle the variable conditions often found in textile mill wastewater.
