Bangladesh – Powerful Coagulation for Textile & Municipal Water Treatment with BLU PAC Series

1. Market Background & Water Treatment Needs

Bangladesh, one of the world's largest textile exporters, is under increasing pressure to meet environmental compliance, particularly in the RMG (ready-made garment) industry concentrated around Dhaka, Gazipur, Narayanganj, and Chattogram. With rising BOD/COD loads, color pollution, and metal contamination in textile effluents, the Department of Environment (DoE) has mandated stricter ETP and CETP regulations for industrial zones.

At the same time, municipal water demand is growing due to urbanization. Safe drinking water is a national priority, particularly for arsenic-affected areas and river-fed supply plants facing high turbidity and pathogen loads.

2. BLU PAC Series: Solutions for Bangladesh’s Water Challenges

Our BLU PAC Series includes high-performance Polyaluminium Chloride (PAC) grades tailored for both industrial effluent treatment and municipal water purification. Available in white (PAC-01) and yellow (PAC-02, PAC-031) powders, each grade is carefully optimized for specific treatment goals.

PAC-01: High-Purity White Powder for Drinking Water

• Al₂O₃ Content: 28–30% min

• Basicity: 45–55%

• Key Benefits:

  • Rapid removal of turbidity, bacteria, and colloids

  • Suitable for rural and urban water plants (e.g. WASA facilities)

  • Safe for arsenic-prone areas due to ultra-low heavy metal residuals

  • Helps meet WHO and Bangladesh National Drinking Water Quality Standards

PAC-02 / PAC-031: Yellow Powder for Industrial ETPs

• Al₂O₃ Content: 28% min (PAC-02), 26% min (PAC-031)

• Basicity: 45–90%

• Applications:

  • Textile dyeing wastewater (high color/COD)

  • CETPs in Gazipur and Narayanganj

  • Paper mills, tanneries, and dye manufacturers

• Performance:

  • Reduces COD by 60–75%, color by 80–95%

  • Effective pH range: 5.0–9.0

  • High floc strength, faster sedimentation = lower energy use in DAF/sedimentation tanks

3. Recommended Dosage & Use Instructions

• Jar Test Required: Always determine site-specific dosage via lab tests.

• Mixing Tip: Use low-speed stirrer for dissolving solid PAC to prevent agglomeration.

• Sludge Management: Generates less sludge than alum; easier dewatering and disposal.

4. Packaging & Delivery

• Solid PAC: 25kg bags (inner PE + outer woven), 20MT/20'FCL

• Liquid PAC: 200L HDPE drums or 1000L IBC tanks

• Lead Time: 5–10 working days

• Documentation: TDS, MSDS, Certificate of Analysis, and export documents available

• Support: Technical support for jar test protocol and on-site optimization

5. Key Benefits for Bangladesh Buyers

• Meets DoE & WASA requirements

• Effective on high-color, high-TDS wastewater

• Fast floc formation reduces retention time in ETPs

• Low residual aluminum for drinking water use

• Works well in saline-affected or variable pH feed water

6. Successful Use Cases in Bangladesh

• Textile ETP (Gazipur): Using PAC-02 at 20g/m³, COD reduced from 1400 mg/L to 380 mg/L; sludge settled in 12 mins.

• Municipal Plant (Khulna): PAC-01 reduced turbidity by 90% with 5g/m³ dosage; passed safe drinking standards without pH adjustment.

• Paper Mill (Chattogram): PAC-031 improved TSS removal efficiency by 70%, enabling reuse of treated water in the process loop.

8. Why Choose BLU PAC for Bangladesh?

• Direct-from-factory pricing with worldwide export support

• High-performance formulation tailored for tropical climates and high organic loads

• Compliant with Bangladesh standards (DoE, WASA)

• Proven success in textile clusters (BTMA members and beyond)

• Full technical support for pilot testing, jar-test setup, and application training
