Application of the NEC in a MBR to treat a synthetic influent with an EE2 concentration of 83 ng EE2 L!1 resulted in a removal efficiency of 99%. Simultaneously, complete nitrification was achieved at an optimal ammonium influent concentration of 1.0 mg NH4þ-N L!1. This minimal NH4þ-N input is very advantageous for effluent polishing since the concomitant effluent nitrate concentrations will be low as well and it offers opportunities for the nitrifying MBR as a promising add-on technology for WWTP effluent polishing.
