The saline wastewater from various sources including agriculture and industrial activities, appears to have high salt concentration, organic content and other pollutants which can harm the environment. Thus, saline wastewater treatment has become one of the major concerns in many countries. Membrane technology offers great potential in saline wastewater treatment due to its high permeate quality, flexibility, and desalination capability. This paper highlights the current development in various types of membrane processes such as pressure driven-based membranes, forward osmosis, membrane distillation, electrodialysis and membrane bioreactor, either as a stand-alone or integrated process for saline wastewater treatment. The membranes performance in terms of water reclamation as well as resource recovery is discussed. Besides, the membrane fouling issue is highlighted, and the efficiency of various fouling mitigation strategies when dealing with real/challenging saline wastewater are reviewed. Finally, the future challenges and outlook in the context of membrane application for saline wastewater treatment are discussed.

含盐废水处理膜技术的当前进展:综合回顾

包括农业和工业活动在内的各种来源的含盐废水似乎具有高盐浓度、有机含量和其他可能危害环境的污染物。因此,含盐废水处理已成为许多国家关注的主要问题之一。由于其高渗透质量、灵活性和脱盐能力,膜技术在含盐废水处理中具有巨大潜力。本文重点介绍了各种类型的膜工艺的当前发展,例如基于压力驱动的膜、正向渗透、膜蒸馏、电渗析和膜生物反应器,作为含盐废水处理的独立或集成工艺。讨论了在水回收和资源回收方面的膜性能。除了,强调了膜污染问题,并审查了处理实际/具有挑战性的含盐废水时各种污染缓解策略的效率。最后,讨论了膜应用于含盐废水处理的未来挑战和前景。
