Extensive research has focussed on the development of novel high retention membrane bioreactor (HR-MBR) systems for wastewater reclamation in recent years. HR-MBR integrates high rejection membrane separation with conventional biological treatment in a single step. High rejection membrane separation processes currently used in HR-MBR applications include nanofiltration, forward osmosis, and membrane distillation. In these HR-MBR systems, organic contaminants can be effectively retained, prolonging their retention time in the bioreactor and thus enhancing their biodegradation. Therefore, HR-MBR can offer a reliable and elegant solution to produce high quality effluent. However, there are several technological challenges associated with the development of HR-MBR, including salinity build-up, low permeate flux, and membrane degradation. This paper provides a critical review on these challenges and potential opportunities of HR-MBR for wastewater treatment and water reclamation, and aims to guide and inform future research on HR-MBR for fast commercialisation of this innovative technology.
近年来，人们广泛致力于开发新型高截留膜生物反应器（HR-MBR）系统，以实现废水再利用。HR-MBR 将高截留膜分离与传统生物处理在一步中集成。目前在 HR-MBR 应用中使用的高截留膜分离过程包括纳滤、正向渗透和膜蒸馏。在这些 HR-MBR 系统中，可以有效地截留有机污染物，延长它们在生物反应器中的停留时间，从而增强其生物降解能力。因此，HR-MBR 可以为生产高质量出水提供可靠和优雅的解决方案。然而，HR-MBR 的开发存在一些技术挑战，包括盐度积聚、低渗透通量和膜降解。本文对这些挑战以及 HR-MBR 在废水处理和水再利用方面的潜在机会进行了批判性回顾，旨在为 HR-MBR 的快速商业化提供指导和信息，推动这一创新技术的未来研究。
