Total Water Treatment Solution for One of India’s Largest Petrochemical Complexes
WABAG delivered the complete water and wastewater treatment infrastructure for the HMEL Petrochemical Complex in Bathinda, Punjab, integrating raw water treatment, effluent treatment and water recycling into a unified and circular system. The project supports seamless production operations at the mega complex while enhancing environmental stewardship and long-term water sustainability.
Multi-Barrier Treatment Platform for High-Efficiency Industrial Water Management
The facility treats complex industrial effluents using a tailor-made multi-stage treatment train incorporating biological, physico-chemical and membrane processes. Treated effluents, combined with cooling tower and boiler blowdown streams, are further polished through RO-based demineralisation to generate high-quality process water for reuse within the petrochemical complex.
High-Performance UF/RO Water Recycling Reducing Freshwater Dependency
A large-scale water recycling system built on ultrafiltration and reverse osmosis significantly minimizes freshwater consumption. By continuously recovering and reusing treated wastewater for process needs, the plant supports resource efficiency and cost-effective refinery operations while ensuring reliable water supply to critical units across the site.
Circular Resource Model Strengthening Sustainability and Regulatory Compliance
The integrated treatment ecosystem not only delivers uninterrupted industrial water supply but also reduces the environmental footprint of refinery operations. The project reinforces circularity by closing the water loop, reducing discharge and supporting the HMEL complex’s long-term sustainability commitments.
Scope of Work
EPC turnkey execution including design and engineering, procurement and supply, civil and electro-mechanical construction, installation, testing and commissioning; followed by 36-month O&M for both the RWTP and ETP.
Technologies and Treatment Process
The advanced multistage treatment includes:
- Equalization
- Coagulation / flocculation
- HRSC clarification
- API & TPI separation
- DAF
- Bioreactor / MBR
- Spent caustic treatment
- Dual media filtration
- Ultrafiltration
- Reverse Osmosis
- VOC treatment
A Leading Example of Large-Scale Water Recycling in the Global Oil & Gas Sector
The system ensures a continuous supply of high-quality industrial water for petrochemical operations, significantly reducing dependence on freshwater sources through large-scale recycling. By enabling cost-efficient refinery operations and supporting job creation in the region, the project contributes meaningfully to economic development. At the same time, it delivers long-term compliance with environmental regulations and strengthens the refinery’s overall sustainability profile by minimizing wastewater discharge and promoting circular resource management.
