TERI develops technology of end-to-end treatment of waste water to achieved zero discharge

The Energy and Resources Institute (TERI) has developed an end-to-end treatment of industrial waste water to achieve zero liquid discharge. Zero liquid discharge (ZLD) is a treatment process for removing all liquid waste from a system. The focus of ZLD is to economically reduce waste water and produce clean water that is suitable for reuse and beneficial for the environment. The treatment technology has been developed by TERI fellow and scientist Nupur Bahadur which involves integrated approaches involving nanotechnology in combination with advanced oxidation processes. This innovation offers clean, green, sludge free and highly resource and energy efficient process, Bahadur said on Wednesday, noting that the technology is at pilot stage and ready for field implementation. The Central Pollution Control Board, in 2015, introduced the concept of ZLD for highly polluting industries. Bahadur said that other than economic feasibility, one of the main reasons for the delay in ...
