The growing environmental concerns associated with elevated levels of ammonium nitrogen in municipalwastewater, along with increasingly stringent discharge regulations, necessitate the development andimplementation of advanced and highly efficient treatment technologies. This study is aimed at optimizing theoperational parameters of a membrane bioreactor system for urban wastewater treatment, focusing on thebalance between treatment performance and operational sustainability. Membrane bioreactor systems offerseveral key advantages over conventional biological treatment methods, including higher biomass retention,improved effluent quality, compact system design, and the ability to support simultaneous nitrification anddenitrification processes within a single reactor. To investigate optimal operating conditions, GPS-Xsimulation software was used to model 36 combinations of filtration duration and washing duration over a10-day dynamic period. The impact of these parameters on critical performance indicators – transmembranepressure, hydraulic load, hydraulic permeability, nitrogen removal efficiency, and washwater consumption –was assessed. The simulations demonstrated that the optimal operating regime involved a filtration durationof 30 minutes combined with a washing duration of 180 seconds. Under these conditions, transmembranepressure was minimized (1,586 kPa), while ammonium and nitrate nitrogen concentrations in the treatedeffluent were effectively reduced to 0.13 mg N/L and 11.36 mg N/L, respectively – well below the regulatorylimits for discharge. Additionally, the system exhibited favorable hydraulic permeability(0.3635 m³/(m²·kPa·day)) and moderate washwater usage (13.1 m³/day), contributing to operational costefficiency and membrane longevity. These results not only confirm the suitability of membrane bioreactortechnology for nutrient removal but also emphasize its practical potential for municipal implementation inUkraine. The study highlights the role of simulation-based optimization in achieving both environmentalcompliance and resource-efficient operation, reinforcing the relevance of membrane bioreactor systems as acore component of modern wastewater management strategies
