New advanced oxidation technology can enhance reuse of waste water at much lower cost

<p>
The Energy and Resources Institute, New Delhi, has developed a new advanced oxidation technology which uses UV-Photocatalysis to treat municipal sewage and highly polluting industrial waste water streams for reuse at a much lower cost. </p>
<p>
The Advanced Oxidation Technology or TADOX ‘can reduce dependence and load on biological and tertiary treatment systems and help achieve zero liquid discharge (ZLD). It can bring down capital expenditure on ZLD by 25-30% and operating expense by 30-40% for industrial wastewater treatment, according to information provided by the Ministry of Science and Environment.</p>
<p>
The technology has been adopted by an MSME Company to scale up to 10 kilo litres per day continuous running plant in TERI’s Gurugram campus. TADOX® technology has been chosen for pilot trials and the augmentation plan for identified industrial sectors being taken up under the  ‘Namami Gange’ programme of the Ministry of Jal Shakti. The Technology is at TRL 7 and ready for commercialization through field implementations and Technology & Trademark License Agreement from 1st April 2021, the official statement said.</p>

<p>
The technology involves UV-Photocatalysis as an advanced oxidation process at the secondary treatment stage leading to oxidative degradation and mineralization of targeted pollutants.</p>
<p>
It improves biodegradability, thereby preventing bio-fouling of membranes and enhancing life span and efficiency of RO systems as also overall load on evaporators like Multiple Effect Evaporators and Mechanical vapor recompression. It can reduce Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), dissolved organics, pathogens, Persistent Organic Pollutants (POPs), and Micropollutants.</p>
<p>
TADOX® could be integrated and retrofitted in existing treatment systems making it a viable option as a novel Decentralized Wastewater Treatment Technology applicable in upcoming and existing infrastructural projects, townships, commercial complexes, green buildings, and smart cities, the official statement explained.</p>
