Industrial Water Recycling for Thermal Power Plants — NTPC Badarpur
WABAG rehabilitated and modernized the complete industrial water supply system for NTPC’s Badarpur Thermal Power Station, treating highly polluted Yamuna river water and converting it into high-purity boiler feed water. The solution ensures reliable water security for 3 × 95 MW and 2 × 210 MW units while supporting circular water use in the power sector.
High-Purity Boiler Feed Water through Advanced MBR-RO Treatment
The plant integrates a multi-stage purification process combining biological treatment with membrane filtration and RO desalination. This enables the removal of suspended solids, nutrients, and dissolved impurities to meet the stringent quality standards required for boiler operations, reducing corrosion risk and improving plant performance.
EPC Rehabilitation for Long-Term Water Sustainability in Power Generation
Executed under an EPC scope (design, engineering, modernization, installation, and commissioning), the project demonstrates WABAG’s expertise in upgrading legacy assets to high-performance industrial water systems. The solution enhances water sustainability while minimizing dependence on freshwater sources.
Scope
Rehabilitation and modernization of the industrial water system, including design, engineering, installation, and commissioning of an MBR-RO system to produce high-purity industrial water.
Technologies
- Pre-treatment — Anoxic and aeration tanks
- MBR (MARAPUR®) — For BOD and nitrogen removal
- Reverse Osmosis (RO) — For dissolved solids removal
- Final application — Boiler feed water supply to the Demineralization (DM) plant
Impact — Circular Water Use for Cleaner and Reliable Power Generation
By transforming highly contaminated river water into high-purity boiler feed water, the plant reduces freshwater withdrawal, improves energy efficiency, and lowers the environmental footprint of the NTPC facility. The project stands as a proven circular water model—turning a pollution source into a valuable industrial water resource.
