- 20 MLD treated water
- 10 MLD demineralised water
- 12 KLD drinking water
The DM plant will include major systems such as pre-treatment, DM water treatment, drinking water facilities with UV treatment and storage, water storage systems, sludge and waste handling systems, air conditioning and ventilation systems, piping networks, fire protection systems, laboratory testing facilities, and associated civil, electrical, and instrumentation works.
The NGEL Green Hydrogen Hub project is expected to support the development of green hydrogen infrastructure in India by creating essential water treatment facilities required for hydrogen production processes.
