WABAG executed the rehabilitation and modernization of the industrial water supply system for NTPC’s Badarpur Thermal Power Station, which includes 3 x 95 MW & 2 x 210 MW units. The plant treats highly polluted Yamuna river water using advanced MBR and RO technologies, making it suitable as feed water for the demineralization unit and ultimately as boiler feed water. Commissioned in 2015, this plant stands as a pioneering example of resource recovery and circular water use in the power sector.

Project Highlights:

• Scope:
  Rehabilitation and modernization of the water supply system including design, engineering, installation and commissioning of an advanced MBR-RO system for producing high-purity industrial water.
• Treatment Process:
  The polluted river water undergoes a multi-stage process:
  • Pre-treatment: Anoxic and aeration tanks
  • MBR (MARAPUR®): For BOD and nitrogen removal
  • Reverse Osmosis: For removal of dissolved solids
  • Final Application: Treated water is fed to the existing DM plant as boiler feed water
• Impact:
  The plant transforms highly contaminated river water into high-purity boiler feed water, enhancing water sustainability and reducing the environmental footprint of thermal power generation. By deploying MBR and RO, WABAG ensures water recovery from a degraded source—turning a pollution problem into a resource solution for industrial application.
