Press release provided by National Institute of Technology-Rourkela
New Delhi, India – 30 January, 2025 – Researchers at the National Institute of Technology (NIT), Rourkela have developed an innovative process for efficiently treating industrial waste water contaminated with persistent dyes such as Bismarck Brown R.
The research, supported by Department of Science and Technology, has been published in the prestigious Journal of Environmental Chemical Engineering and the team has been granted a patent for the developed technology.
According to Sujit Sen, Professor, Department of Chemical Engineering at NIT-Rourkela in Odisha, waste water from industries like textiles and dye manufacturing often contains harmful dyes that are difficult to remove with traditional filtration methods. This technology could be applied across industries such as textile manufacturing, chemical, steel, petrochemical and pharmaceutical where robust wastewater treatment is required. It can also be scaled up and integrated into existing treatment plants to improve the efficiency of treating dye-laden wastewater.
