Abstract	This work studies the performance of a Biological Nutrients Removal (BNR) plant operated with two different flow patterns. In the feed distribution pattern before the anaerobic selector, the influent wastewater is distributed to the anaerobic selector and to the second and third anoxic tank, whereas according to the feed distribution pattern after the anaerobic selector, the influent wastewater is firstly introduced to the anaerobic selector and afterwards distributed to the three anoxic zones. In both cases, removal efficiency of organic, nitrogenous and phosphorous contaminants was satisfactory. However, the feed distribution pattern after the anaerobic selector led to an increase of total phosphorus removal and an extreme deterioration of sludge settleability, which did not cause insufficient clarification. The feed distribution pattern before the anaerobic selector showed a more efficient performance.
