New advanced oxidation technology can enhance wastewater reuse at lower cost

The Department of Science and Technique (DST) announced on Wednesday that a new UV-photocatalysis technology can cure municipal sewage and highly polluting industrial wastewater streams, allowing them to be reused.

The existing treatment methods are ineffective due to a strong reliance on biological treatment systems, which are unable to withstand shock loads, according to the report. The DST added in a statement that tertiary treatment techniques such as reverse osmosis and Multi Effect Evaporators (MEE) are used after that.

According to the report, these technologies have a big carbon footprint and high maintenance costs, making wastewater treatment unsustainable and pricey.

As a result, academics believe that fresh ideas and advanced technology should be integrated into present systems, according to the DST.

The Energy and Resources Institute (TERI) in this city has created a method dubbed Advanced Oxidation Technology or TADOX, which it claims can help achieve zero liquid discharge (ZLD) by reducing reliance and strain on biological and tertiary treatment systems.

For industrial wastewater treatment, it can reduce capital expenditure on ZLD by 25-30% and operating expenses by 30-40%. According to the DST, an initiative in this area is TADOX, a wastewater treatment system created by TERI in New Delhi.

According to the statement, the DST-Water Technology Initiative (WTI) has helped TERI develop this technology at a bench size in partnership with the ONGC Energy Centre (OEC) here.

UV-Photocatalysis is used as an Advanced Oxidation Process (AOP) at the secondary treatment stage, resulting in oxidative destruction and mineralization of specific contaminants, according to the company.

It enhances biodegradability, reducing membrane fouling and extending the life and efficiency of RO systems, as well as the total load on evaporators such as multiple effect evaporators and mechanical vapour recompression, according to a DST statement.

It can lower chemical oxygen demand, biological oxygen demand, dissolved organics, pathogens, persistent organic pollutants, and micropollutants, according to the company.

According to the statement, TADOX could be integrated and retrofitted into existing treatment systems, making it a viable option as a novel decentralised wastewater treatment technology (DWTT) for future and existing infrastructure projects, townships, commercial complexes, green buildings, and smart cities.

An MSME company at TERI’s Gurgaon campus has embraced the technology to scale up to a 10 kilo litre per day continuous functioning facility, according to the institute.

According to the release, TADOX technology has been selected for pilot trials and an augmentation plan for targeted industrial sectors under the Ministry of Jal Shakti’s ‘Namami Gange’ Programme.

The technology is ready for commercialization, according to the company, with field deployments and a Technology and Trademark License Agreement in place as of April 1.
