The amount of research conducted on osmotic membrane bioreactors (OMBRs) has increased over the past decade because of the advantages of these reactors over conventional membrane bioreactors (MBRs). OMBR process is a hybrid process involving a forward osmosis membrane and biologically activated sludge. It is a promising technology to reduce membrane fouling, enhance effluent water quality, and lower energy consumption compared to conventional MBR processes. Eleven years since the OMBR process was first proposed, about 60 papers regarding the OMBR process have been published. In this article, we address recent advances in OMBR technology based on a review of the literature. Typical factors that influence the performance of the OMBR process are discussed to provide a clear understanding of the current state of this technology. We also provide a critical review of OMBR applications in organic matter, nutrient, and micropollutant removal as well as direct recovery of nutrients from wastewater. We propose several hybrid configurations that can enhance the removal efficiency of OMBR systems. Finally, we present potential research directions for future OMBR research.
在过去的十年中，由于渗透膜生物反应器（OMBR）相对于传统膜生物反应器（MBR）具有优势，因此对其进行的研究有所增加。OMBR 工艺是一种涉及正向渗透膜和生物活性污泥的混合工艺。与传统的 MBR 工艺相比，它是一种有前途的技术，可以减少膜污染、提高出水水质和降低能耗。自 OMBR 工艺首次提出以来的十一年中，已经发表了约 60 篇有关 OMBR 工艺的论文。在本文中，我们根据文献综述介绍了 OMBR 技术的最新进展。讨论了影响 OMBR 工艺性能的典型因素，以清楚地了解该技术的现状。我们还对 OMBR 在有机物、营养物和微污染物去除以及从废水中直接回收营养物方面的应用进行了批判性评价。我们提出了几种可以提高 OMBR 系统去除效率的混合配置。最后，我们提出了未来 OMBR 研究的潜在研究方向。
