The Advanced Oxidation Technology: Sustainable Solution to treat wastewater

We are uncertain about the future of water. There are many factors to support the above-said statement. The world is experiencing an ever-increasing demand for water, subsequent reduction of water resources, and increasing water pollution that is driven by dramatic population and economic growth. Various initiatives at different levels are being taken to conserve water for the future. One such initiative has been taken by ‘The Energy and Resources Institute’, New Delhi who has come up with a technology that can treat municipal sewage and extremely polluted industrial wastewater streams. Named ‘The Advanced Oxidation Technology, this technology may soon be put to enhance the reuse of wastewater in a cost-effective and sustainable manner.

The technology in highlight: Advanced Oxidation

Over the years it has become pertinent for industries and utilities to reuse ‘treated water’. But the current treatment practices of municipal sewage and wastewater streams are ineffective and insufficient due to high dependence on biological treatment systems. This is further followed by tertiary treatment systems that involve RO (Reverse Osmosis) and Multi Effect Evaporators (MEE). These hefty systems have immense carbon footprints along with maintenance costs which in turn makes the whole wastewater treatment process ‘unaffordable’ and ‘unsustainable’. Keeping these factors in mind, the researchers at TERI (The Energy and Resources Institute) felt the need to integrate innovative approaches and advanced technologies in the present systems.

Advanced Oxidation Technology or TADOX uses UV-Photocatalysis that can treat municipal sewage and extremely highly polluting industrial wastewater streams. The technology is capable of reducing less dependence and subsequent load on tertiary treatment systems. In addition, this technology can help in achieving Zero Liquid Discharge (ZLD). The Advanced Oxidation Technology can bring down capital expenditure on Zero Liquid Discharge (ZLD) by 25-30% and operating expense by 30-40% for industrial wastewater treatment.

At the secondary treatment stage, the technology involves UV-Photocatalysis as an Advanced Oxidation Process (AOP) that leads to oxidative degradation and mineralization of targeted pollutants. This improves biodegradability, thereby preventing biofouling of membranes and enhancing the life span and efficiency of RO systems.

The technology serving the future:

Improving the existing treatment systems, TADOX could easily be integrated to make it a viable option as a novel Decentralized Wastewater Treatment Technology (DWTT). This technology will be applicable in upcoming and existing infrastructural projects, townships, commercial complexes, green buildings, and smart cities.
