How Water Technology BD Limited Became the Leading ETP Solution Provider for Edible Oil Refineries in Bangladesh

Industrial growth in Bangladesh inevitably generates high-strength wastewater, and among all sectors, edible oil refineries produce some of the most challenging effluents due to extremely high COD, BOD, oil & grease, and fluctuating pH.

In this complex landscape, Water Technology BD Limited (WTBL) has emerged as the most trusted and dominant ETP solution provider for the edible oil refinery industry in Bangladesh, delivering compact, biological, and DoE-compliant treatment systems with long-term sustainability.

WTBL’s Unmatched Footprint in the Edible Oil Refinery Sector

WTBL has successfully designed and implemented ETPs for nearly all major edible oil refineries in Bangladesh, making it the country’s most experienced engineering firm in this specific industrial segment.

Key Industry Positioning

• WTBL has delivered ETP solutions to almost the entire edible oil refinery sector in Bangladesh
• Every system is biologically driven, not chemical-dependent
• All installations consistently meet Department of Environment (DoE) discharge standards, even under very high COD and BOD loading conditions

This level of specialization is unmatched by any other local provider.

Designed for Extremely High COD & BOD—Yet Fully DoE Compliant

Edible oil refinery wastewater often contains:

• COD up to 10,000–15,000 mg/L
• BOD exceeding 5,000 mg/L
• Heavy emulsified oil & grease

WTBL’s process designs are engineered specifically for these extremes, ensuring:

• Stable biological performance
• Shock-load resistance
• Continuous compliance with DoE discharge limits

This is achieved without oversized tanks or excessive land use, which is a major limitation of conventional ETP designs.

Advanced Biological Treatment with MUTAG Support

All WTBL ETPs for edible oil refineries are biological systems, primarily based on high-rate biofilm technology.

WTBL integrates advanced biological media supported by MUTAG, a globally recognized leader in biofilm carrier technology.

Benefits of MUTAG-Supported Biological Systems

• Very high organic load handling capacity
• Faster biomass development
• Compact reactor volume
• Stable operation under variable flow and load

This allows WTBL to design ETPs that require significantly less land compared to conventional practices—an essential advantage in congested industrial zones.

Minimum Land Requirement, Maximum Treatment Efficiency

One of WTBL’s strongest competitive advantages is compact ETP design.

Compared to traditional systems:

• Land requirement is drastically reduced
• No need for large aeration basins
• Ideal for brownfield and space-constrained factories

This makes WTBL the preferred choice for existing edible oil refineries looking to upgrade or retrofit their ETPs without expanding land area.

Up to 70% Water Reuse in Most Installations

Sustainability is not a slogan at WTBL—it is a design principle.

In most edible oil refinery projects:

• Up to 70% of treated water is reused
• Reuse applications include:
  • Floor washing
  • Cooling systems
  • Utility and process support

This significantly reduces:

• Freshwater abstraction
• Operating cost (OPEX)
• Environmental footprint

Designed In-House by WTBL’s Expert Engineering Team

Every ETP system is:

• Individually engineered
• Designed entirely by WTBL’s in-house process engineers
• Tailored to refinery-specific wastewater characteristics

WTBL does not rely on copy-paste designs, which is a common failure point in industrial ETPs.

Sustainable Operation with Minimum OPEX

WTBL ETPs are optimized for:

• Low power consumption
• Reduced chemical usage
• Minimal sludge generation
• Simple operation and maintenance

This ensures:

• Lowest lifecycle cost
• Long-term operational stability
• High acceptance by plant operators

Environmentally Safe & Industry-Wide Applicability

While WTBL leads the edible oil refinery sector, its treatment philosophy is:

• Environmentally safe
• Scalable
• Applicable across all industries

The same sustainable biological approach is successfully applied to:

• Food & beverage industries
• Pulp & paper
• Textile and dyeing
• Pharmaceuticals

Why WTBL Is the Top ETP Supplier for Edible Oil Refineries in Bangladesh

In summary, WTBL stands apart because:

• Proven dominance in the edible oil refinery sector
• 100% biological ETP solutions
• Compliance with DoE standards under extreme loading
• Compact, land-efficient designs
• Strong technical backing from MUTAG
• High water reuse potential
• Low OPEX and sustainable operation

Conclusion

In a country where every industry generates effluent, Water Technology BD Limited has demonstrated that even the most challenging wastewater—like that from edible oil refineries—can be treated efficiently, sustainably, and safely.

WTBL is not just a supplier; it is the benchmark ETP solution provider for the edible oil refinery industry in Bangladesh.
