“…Thereafter, the treated water was passed through an in-house designed and developed assembly utilising suitable filtration to separate used nanomaterial. Finally, treated water was obtained and spent nano-catalyst was recovered (Bahadur & Bhargava 2019;Bahadur et al 2020;Das et al 2020;Bahadur 2021).…”

“…As per Equation ( 1), E EO has been computed with respect to order removal of COD. This parameter is critical in estimation of the overall cost of treatment and an important parameter for upscaling photocatalytic processes such as TADOX ® for field applications (Bahadur et al 2020;Ghaffarian Khorram & Fallah 2020). where, P is the electrical power consumption (in kW), t denotes the time of treatment in hours and V is the volume of wastewater treated in m 3 .…”

“…In this context, The Energy and Resources Institute (TERI), New Delhi has developed advanced oxidation nanotechnology (AON) -based wastewater treatment technology called TERI Advanced Oxidation Technology (TADOX ® ), which has proved to be beneficial enough to be integrated in current systems to fill the gaps. Complete details of the technology and the process flow have been published and discussed in earlier reports (Bahadur & Bhargava 2019;Bahadur et al 2020;Das et al 2020). Some of the advantages of the advanced oxidation process (AOP)/AON approach are the minimal addition of chemicals, recovery and reuse of used nanomaterials and simultaneous destruction of recalcitrant organics and bio-pollutants including pathogens such as viruses and bacteria (Oturan & Aaron 2014).…”

The current problem with industrial wastewater treatment is that we rely heavily on biological treatment systems without realising that these have severe limitations in terms of shock load bearing capacities, ineffectiveness against removal of toxicity and recalcitrant and dissolved organics. However, biological systems have their own benefits as well. Therefore, it is essential to support them with integration of advanced oxidation nanotechnology (AON) interventions, which are expected to address these challenges. In this pursuit, The Energy and Resources Institute (TERI) has developed an AON based wastewater treatment technology called TERI Advanced Oxidation Technology (TADOX®). This paper presents two sections of three case studies each, to showcase how TADOX® Technology intervention at Pre-biological and post-biological treatment helps in achieving adequate treatment. In the first section, TADOX® has been implemented at pre-biological stage for three highly polluting streams from (i) phenolic wastewater from a 2,4-Dichlorophenoxyacetic acid (2,4 D) plant from a Pesticide manufacturing company, (ii) Phenolic wastewater from Anisole plant of a Chemical industry, and (iii) hydrocarbon rich effluent from Oil & Gas sector. Pre-biological integration is expected to support biological treatment by reduction in COD, toxicity, microbial growth hindering compounds and increase in biodegradability (BOD to COD ratio). The second section in the paper explores the implementation potential of TADOX® to treat biologically treated streams from (i) pharmaceutical, (ii) Tannery and (iii) slaughterhouse. The Post biological integration is expected to remove residual COD, Colour, BOD and Odour leading to treated water meeting norms for safe surface discharge and water reuse. Presented studies from India may be useful and relevant to other developing countries like Bangladesh, Sri Lanka, Vietnam, Indonesia, Taiwan etc. as a possible approach to sustainably manage water resources, together meeting the challenges of economic growth, industrial development, and environmental compliance.

“…AOPs in textile wastewater treatment lines plants could find large-scale application due to the presence of non-biodegradable components that cannot be removed by "phase-transfer" treatment processes, but must be permanently withdrawn. The efficiency of H2O2/UV processes can be enhanced by adding common catalysts such as like Fe(II), Fe(III), ZnO or TiO2 [5][6][7][8][9][10][11][12][13][14][15].…”

In this work, the treatment efficiency of advanced oxidation processes H2O2/UV enhanced by the addition of a manganese catalyst complex (MnTACN) was investigated on a model dye solution and a real dye-house effluent. The experimental results were evaluated in terms of absorbance (A) and total organic carbon (TOC) reduction. The major degradation products of the model dye solution were identified by high resolution gas chromatography/mass spectrometry analyses. In addition, the toxicity of the final reaction solution after H2O2/UV/MnTACN treatment to Vibrio fischeri bacteria was determined. The results showed that the addition of the H2O2/UV/MnTACN system at in different concentrations of the catalyst solution increased enhance the decolourization rate compared to H2O2/UV for both the model dye solution and real dye-house effluent.
