dc.description.abstractThe olive pomace oil is the principal by-product in the olive oil sector. Nonetheless the production uses olive bagasse after the primary extraction, it also produces by-products and effluents that need strategic approach to possibility reuse and a treatment. This study aimed for the characterization of the effluent from an olive pomace oil extractor industry and investigate the application of physicochemical pre-treatments to future water reuse. The physicochemical characterization shows high amounts of BOD and COD for the effluent freshly produced (E1) and effluent collected from storage tanks (E2) in the industrial plant. Other parameters were evaluated: Phosphorus, Organic nitrogen and Ammonia, FOG, Phenolic compounds, Alkalinity, TS, TDS and TSS, and Biodegradability (Zahn-Wellens Test). E2 shows the storage tanks were able to reduce 55% of TS and TDS, 77.5% of COD and 69% of BOD when compared with E1. Comparing with the Portuguese legislation, these effluents cannot be discharge to waterbodies and need treatments, such as coagulation and flocculation as tested in this work. Aluminium Sulphate show to work at best as a coagulant in the minimum concentration 10 g/L and pH 5, RIFLOC F45 (4 mg/L) was used as flocculant. After the treatment, it was observed a remotion of 95.6% of turbidity, 76,4% of COD,76,7% of TSS, and 85.4% of PhC when compared with E2. A sampling campaign was carried out on the Tua river to assess its water quality, and samples were taken at four different points to assess the impact of the effluent discharge, with none of the evaluated parameters presenting values higher than those recommended by the Law-Decree no236/98 from the Portuguese Legislation.pt_PT
