Researchers from IIT Kanpur, Malviya National Institute of Technology, Jaipur, and MBM college Jodhpur have developed a modified and low-cost Advance Oxidation Process technology that can convert toxic and highly carcinogenic industrial dyes of textile effluents into treated distilled water that can be reused as well.
As a pilot project, the technology has already been installed in the Textile Innovative Park, Jaipur in collaboration with The Department of Science and Technology, GoI, and the National Academy of Engineering. The new technology developed by scientists is said to distill industrial wastewater that can be completely reused. The modified AOP can eliminate the toxicity of industrial dye water, converting it suitable for domestic and industrial purpose. The new AOP technology targets zero discharge and reuses all industrial dye wastewater for domestic and industrial usage at a rate of 10,000 liters a day.
The Ministry of Science has mentioned that the advanced technology can recoup 50 percent of the treatment cost incurred from the conventional process of water treatment. The technology has full potential to directly replace the existing conventional water treatment plants. And most importantly, the newly revised AOP technology is enormously cost-effective that provides a low-cost solution of dye adsorption on acid-modified soil followed by a photo-chemical reaction step within a photocatalytic visible light filter and a unique carbon and PAN nano-mat fiber filtration process.
Currently, the textile industry uses 3-stages of dye wastewater treatment consist of the primary, secondary, and tertiary stages. However, even after receiving three stages of treatment, the conventional system is unable to treat the toxic waste completely.
On a contrary, the new AOP technology has been introduced as a stand-alone medium as it not only eliminates the need for costly conventional 3-stages water treatment but, completely treats the industrial dye toxic waste.
