Industrial Effluent Treatment Excellence

At Brothers Engineering BD, we specialize in high-performance ETP Design Solutions tailored for the complex industrial landscape of Bangladesh. Our engineering approach focuses on removing toxic pollutants, dyes, and chemical oxygen demand (COD) from industrial discharge, ensuring your facility remains 100% compliant with national and international environmental standards.

Our Core ETP Engineering Expertise

• Biological ETP Design: Utilizing Aerobic and Anaerobic processes to break down organic matter in textile and food processing wastewater.

• Chemical/Physicochemical ETP: Precision-engineered flash mixers and flocculation tanks for the removal of heavy metals and suspended solids.

• Zero Liquid Discharge (ZLD): Advanced recovery systems that recycle 95% of treated effluent back into the production line.

• Combined ETP (CETP): Strategic design for industrial zones where multiple units share a centralized treatment facility.

Our Technical Design & Approval Process

To deliver a sustainable ETP Design Solution, our technical team follows a rigorous 5-step engineering protocol:

1. Influent Characterization: Detailed lab analysis of your raw effluent (pH, TDS, Color, BOD, COD, and Oil/Grease).

2. Hydraulic Design & PFD: Calculating the retention time and flow rates to ensure the treatment tanks are sized correctly for your production volume.

3. Electro-Mechanical Selection: Specifying air blowers, surface aerators, and chemical dosing pumps that offer the lowest energy consumption.

4. Civil & Structural Layout: Providing high-precision 2D and 3D drawings for the construction of RCC tanks and filtration rooms.

5. DOE Clearance Support: Drafting the “Environmental Management Plan” (EMP) required for obtaining and renewing your Environmental Clearance Certificate (ECC).

Why Professional ETP Design is Essential

In the current regulatory environment, a “cheap” design often leads to factory closures. Professional ETP Design Solutions provide:

• Operational Cost Savings: We optimize chemical dosing and aeration energy, which are the highest ongoing costs in wastewater treatment.

• Sludge Management: Our designs prioritize efficient sludge thickening and dewatering, reducing the cost of hazardous waste disposal.

• Global Compliance: For RMG and textile exporters, our designs meet the ZDHC (Zero Discharge of Hazardous Chemicals) and HIGG Index requirements demanded by international buyers.

• Installation & Maintenance Support

  Our team provides on-site installation and testing. We also offer Annual Maintenance Contracts (AMC) where we perform periodic pressure checks and media replenishment. For industrial clients in Bangladesh, having a robust ETP Filtration Vessel from Brothers Engineering BD means peace of mind, knowing that your factory’s environmental footprint is being managed by professionals.

Specialized ETP Categories

• Textile & Dyeing ETP: Specialized color removal technology using ozone or advanced oxidation.

• Washing Plant ETP: High-efficiency grit removal and neutralization systems for denim washing units.

• Pharmaceutical ETP: Advanced filtration and oxidation to remove active pharmaceutical ingredients (APIs) from wastewater.

Advanced Multi-Port Valve (MPV) Control

To simplify operation, each vessel comes equipped with a high-durability Multi-Port Valve. This allows the operator to switch between four critical functions with a simple turn of a handle:

• Filter Mode: Normal operation for daily water treatment.

• Backwash: Reversing the flow to lift and clean the media bed of trapped debris.

• Rinse: Settling the media after a backwash to ensure clean water starts flowing again.

• Waste/Bypass: Diverting water directly to discharge when the filter is not required.

Frequently Asked Questions (FAQ)

• Do you design Biological or Chemical ETPs? We design both. The choice depends entirely on the BOD/COD ratio of your wastewater and your space availability.

• Can you upgrade an existing ETP? Yes. We provide “ETP Facelifts” where we optimize your current tanks with better aeration and filtration media to improve discharge quality.

• What is the standard for treated water discharge? We design specifically to meet the standards set by the Environment Conservation Rules (ECR) of Bangladesh.
