Sedimentation is still the most common method of biomass separation at majority of medium and large biological nutrient removal municipal wastewater treatment plants (BNR WWTP). In recent years some plants have been replacing this process with membrane separation and transforming their typical biological reactors into membrane units (MBR). This is often linked to the required increase in plant’s capacity and/or improvement in effluent quality. However, such modifications significantly affect plant functioning especially in regard to operation of biological processes, energy management and solids treatment. The article presents the results of computer simulation research on effects of the introduction of membrane filtration at a municipal BNR plant. The simulations allow to compare the most important operational parameters and effluent quality for the traditional layout with secondary clarifiers and the layout with membrane biological rectors. Wastewater treatment plants’ operators and decision-makers may use is it as an indication of what changes in plant operation can be expected after installing membrane filtration.
