There is a growing interest in enhancing the sustainability of wastewater treatment by producing high quality effluents with reduced energy consumption. The membrane aerated biofilm reactor (MABR) has considerable potential in this regard due to its promise of high oxygen transfer efficiencies (OTEs) with low energy input. There has however been limited optimization of MABRs at full scale. The proposed study will optimize the operation of a full scale MABR facility that is currently under construction at the Hespeler, Ontario wastewater treatment plant. The impact of solids residence time, organic loading and oxygen supply on key performance metrics related to energy consumption and effluent quality will be assessed. Specifically, the ability to achieve total nitrogen and micro pollutant removal will be emphasized. The impact of operating conditions on the composition of the microbial communities will be examined to obtain insight into the active metabolisms in the system. The results of this study will be of broad interest to the wastewater community (regulators, wastewater treatment plant owners and operators, consulting engineers, technology providers) as there is a significant demand for technologies that can be employed to upgrade treatment in a sustainable manner.

人们越来越感兴趣的是，通过产生高质量的废水并减少能源消耗来提高废水处理的可持续性。膜曝气生物膜反应器(MABR)在这方面具有很大的潜力，因为它可以以较低的能量输入实现高的氧气传递效率(OTES)。然而，全面优化MABR的工作有限。这项拟议的研究将优化安大略省黑斯佩勒污水处理厂目前正在建设的全规模MABR设施的运行。将评估固体停留时间、有机负荷和氧气供应对与能源消耗和出水水质相关的关键性能指标的影响。具体而言，将强调实现总氮和微污染物去除的能力。将检查操作条件对微生物群落组成的影响，以深入了解系统中的活跃代谢。这项研究的结果将引起废水社区(监管者、废水处理厂所有者和操作员、咨询工程师、技术供应商)的广泛兴趣，因为对可用于以可持续方式改进处理的技术有很大的需求。
