Won the “Best STP/ETP/WWTP – Private” award for its NMDC ZLD Plant at the Water Digest World Water Awards 2023 – 24

WABAG was honored with the “Best STP/ETP/WWTP – Private” award for its Centralized Zero Liquid Discharge (CZLD) Plant designed and executed for NMDC Steel Ltd at the Water Digest World Water Awards 2023 – 24. The Honorable Minister for Jal Shakti, Shri Gajendra Singh Shekhawat, presented the award to Team WABAG.

Leveraging advanced technologies, the plant efficiently manages various effluents produced during steel production, achieving an impressive 90% overall efficiency through a multi-stage process, which includes a Reject Reverse Osmosis unit and a Multiple Effect Evaporator with a capacity of 180 m3/h. The ZLD plant demonstrates versatility by treating wastewater from 15 different sources, including those with high Total Dissolved Solids.

Effluents containing high levels of Cyanides, Organic Pollutants, Oil & grease, and Dark-colored impurities, which are off-spec in nature, are handled in the ETP and treated to meet recycling norms for reuse in the utility section of the plant. RO reject with high Dissolved salts passes through a Multi-effect evaporator, with condensate utilized for utility purposes, while the crystallized salt is disposed of in a secured landfill.

With its core mission to achieve Zero Liquid Discharge, the plant treats effluent from NMDC Steel Ltd., facilitating the recycling and reuse of treated effluent as makeup cooling water. This strategic approach establishes a closed water circuit, seamlessly aligning with the ste4el plant’s commitment to achieving wastewater-free production. As one of the largest centralized ZLD facilities in the Indian Steel Industry, this project holds operational significance and contributes to sustainable development goals.

Sustainable solutions. For a better life.
