Abstract (EN): The present research is based on a case-study involving the development of an adequate treatment for agro-effluents originating from wineries. Flocculation, Fenton's oxidation and ozonation processes were investigated in order to define the best integration strategy that may conduce to optimal efficiency of degradation and operational cost. Chemical oxygen demand (COD), total suspended solids (TSS), and total organic carbon (TOC) were some of the parameters used to analyze the performance of these technologies. The higher COD and TSS removals (73% and 94% respectively) were achieved combining the ozonation treatment with the Fenton process. In addition, the respective cost of COD reduction is lower in this case, when compared with other alternatives. Flocculation revealed not to be needed since in the ozonation process the suspended solids are able to be degraded.
