The choice of an effluent treatment system must take into account technical and economic aspects, among which the process efficiency. The objective of this research was to evaluate the removal of nitrogen and phosphorus in an anaerobic-aerobic fixed bed reactor, operated at bench scale, with recirculation of the liquid phase. The reactor, with a volume of 6.95 L, was operated with polyurethane foam support and maintained at room temperature with the synthetic effluent treated by simulating the sewage. Different recirculation ratios were tested (0.5, 1.0 and 1.5) and different HRT (4, 8, and 12) with constant air flow rate of 10 L min-1. With the variation of these factors was possible to verify the influence of the recirculation ratio on ni...
