Wastewater contamination is typically characterized by a combination of organic and inorganic compounds rendering treatment relying on a single treatment approach almost always unfeasible. The treatment of complex waste matrices not only poses the process challenge of reducing the concentration of a number of contaminants to safe levels but also achieving it through an efficient, affordable and simple process. A key challenge in achieving this is the identification of techniques that operate symbiotically to enhance the performance of the system as a whole. Here such process symbiosis is presented, through the treatment of a model effluent containing iron and nitrobenzene, by Electro-Coagulation (EC) and Photooxidation (PO), individually and in combination. It was found that the combination of two the techniques, which individually were unable to completely remove contamination, achieved 100 % contaminant removal in a shorter reaction time and consuming less H2O2.
