The work aimed to remove organic matter and nutrients from effluents from a fish processing industry. The work was carried out in the sanitation laboratory of UFMG. The two-stage treatment system was carried out on a bench scale, consisting of an anaerobic reactor with a Y-shaped sludge blanket (UASB in Y ) and coupled to it a percolating filter (FA) with oyster shells as filling material. . The mean temperature values of the UASB reactor effluents in Y and FA did not vary in a range unfavorable to anaerobic digestion. The pH in tests 1 and 2 remained close to the neutrality range. The mean values of the global total COD removal efficiencies in tests 1 and 2 were 82 and 83% respectively. The average values of global COD removal filtered in trials 1 and 2 were 44.5% and 72%, respectively. In trials 1 and 2, the global system did not show satisfactory nutrient removal efficiency. It can be concluded that the system is recommended to treat effluents from fish processing, with no significant differences between the tests regarding its efficiency in the secondary treatment.
