NEHU team patents technology to treat industry effluents
Staff Reporter
 GUWAHATI, Dec 14 - Three researchers from the Shillong-based North Eastern Hill University (NEHU) have patented an innovative, energy efficient, economically viable and environment-friendly technology for treatment and bio-detoxification of azo-dye-contaminated wastewater effluent from industries, said a press release here today.

Azo dye is abundantly produced by many industries, including textile, leather and paint industries among others.

In this technology, the team of three NEHU scientists – Dr MK Sahoo and Bhauk Sinha of Department of Chemistry and Prof RN Sharan, Radiation and Molecular Biology Unit of Department of Biochemistry – has successfully identified and overcome the factors responsible for continuing bio-toxicity in the wastewater effluents after treatment with the technology available today.

The first-of-its-kind technology, developed by the NEHU team, combines the powers of UV radiation and chemical oxidation systems in a unique formulation to exploit optimum and simultaneous outcome of wastewater treatment as well as bio-detoxification.

As a result, the wastewater treated by this technology is free from pollutants as well as bio-toxicity making it environmentally benign to bio-flora and fauna and fit for release into the environment.
