With regard to global concerns, such as water scarcity and aquatic pollution from industries and domestic activities, membrane-based filtration for wastewater treatment has shown promising results in terms of water purification. Filtration by polymeric membranes is highly efficient in separating contaminants; however, such membranes have limited applications. Nanocomposite membranes, which are formed by adding nanofillers to polymeric membrane matrices, can enhance the filtration process. Considerable attention has been given to nanofillers, which include carbon-based nanoparticles and metal/metal oxide nanoparticles. In this review, we first examined the current status of membrane technologies for water filtration, polymeric nanocomposite membranes, and their applications. Additionally, we highlight the challenges faced in water treatment in developing countries.
关于全球关注的问题，例如水资源短缺以及工业和家庭活动造成的水污染，基于膜的废水处理过滤技术在水净化方面已显示出令人鼓舞的成果。聚合物膜过滤在分离污染物方面效率很高；然而，这类膜的应用有限。通过向聚合物膜基质中添加纳米填料形成的纳米复合膜可以增强过滤过程。人们对纳米填料给予了相当多的关注，其中包括碳基纳米颗粒和金属/金属氧化物纳米颗粒。在本综述中，我们首先研究了用于水过滤的膜技术、聚合物纳米复合膜及其应用的现状。此外，我们还强调了发展中国家在水处理方面面临的挑战。
