In this work it is presented the results of bench scale tests using Advanced Oxidation Process (AOP) in a UV/H2O2 system, for the treatment of an industrial effluent with a high concentration of dissolved organic matter, resulted from thermal treatment of oil-water emulsions. Treatability tests were carried out in a batch photochemical system with recycle, and the raw effluent was characterized by the analysis of pH, turbidity, color, COD and TOC. Results from these assays shown that UV/H2O2 process is technically feasible resulting in TOC removal above 90%. However, for one log TOC removal from this effluent the energy required was about 455.5 kw.h.m-3, for an alpha relation of 10 mg H2O2/mg COT, resulting in a higher operational cost, considering the evaluated conditions.
