TERI Advanced Oxidation Technology (TADOX) offers clean, green, sludge-free, cost-effective and resource-efficient treatment of wastewater streams, enabling Zero Liquid Discharge and enhancing water re-use efficiency
New Delhi: The Energy and Resources Institute (TERI) and Perfact Group have ventured into a collaboration to promote TERI’s patent-pending technology, TERI Advanced Oxidation Technology (TADOX) for comprehensive treatment of wastewater.
The technology offers end-to-end treatment of industrial wastewater or mixed streams with untreated sewage or municipal wastewater, containing high colour, Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Organic Carbon (TOC), dissolved organics, non-biodegradable or persistent organic pollutants (POPs).
The treatment integrates nanotechnology with Advanced Oxidation Processes (AOPs), which together is referred to as Advanced Oxidation Nanotechnology (AON).
In 2015, the Central Pollution Control Board (CPCB) introduced the concept of Zero Liquid Discharge (ZLD) for highly polluting industries. Under its ZLD scheme, identified industries were prohibited from discharging treated or untreated wastewater out of their premises, and mandated to and completely treat, reuse and recycle treated wastewater before its emission.
Dr Alok Adholeya, Director, TERI-Deakin Nano Biotechnology Centre, TERI said, “If the industrial sector can completely achieve ZLD, it may be able to solve the interlinked problems of groundwater depletion, freshwater availability, efficient water management and water conservation.”
Despite substantial progress over the years, achieving Zero Liquid Discharge (ZLD) has posed challenges, necessitating wastewater treatment innovation. Nanotechnology holds greater promise for much more efficient, faster and adequate treatment, as compared to conventional protocols and TERI has taken steps in that direction, he added.
Currently deployed technologies incur a huge cost to achieve the mandated standards of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) wastewater treatment.
Highlighting the benefits of TADOX, the technology’s inventor Dr Nupur Bahadur, Fellow, TERI-Deakin Nano Biotechnology Centre, TERI, said, “TADOX involves limited use of externally added chemicals and the overall process – which completely degrades and mineralizes suspended as well as dissolved organics – is highly efficient. Further, the treatment process generates a negligible amount of non-toxic sludge, which is reduced from the industry average of 42.6 kg/m3 to 0.4 kg/m3, which reduces the burden of sludge disposal and management and ultimately prevents secondary pollution.”
