Scholarcy highlights

  • Water being one of the essential resources for the survival of living organisms on earth, has always been the topic of interest for researchers
  • Effect of Time and pH The collected sample was subjected to the electro-oxidation process at the sample pH to optimize the time required for the degradation of organic pollutants contained in the wastewater sample
  • The integration of electrochemical oxidation with membrane bioreactor exhibits a better performance with an effective percentage removal of Chemical Oxygen Demand, Total Organic Carbon, Total Nitrogen, and Chlorides such as 97%, 90%, 94%, and 71% respectively
  • Field Emission Scanning Electron Microscope images of the membrane used in the integrated EO pretreatment to MBR illustrated that the reduction in biofouling compared to the MBR process
  • The results obtained from the Gas Chromatography with Mass Spectrometer, toxicity tests prove that IEOMBR shows a complete mineralization process and an integrated process ensures the viability of pilot plant study and eco-friendly to the process plant
  • The above results are a path to accept that the electro-oxidation as pretreatment for the MBR process resulting in reduced biofouling
