Membrane technology remains the most energy‐efficient process for removing contaminants (micrometer‐size particles to angstrom‐size hydrated ions) from water. However, the current membrane technology, involving relatively expensive synthetic materials, is often nonsustainable for the poorest communities in the society. In this article, perspectives are provided on the emerging nanocellulose‐enabled membrane technology based on nanoscale cellulose fibers that can be extracted from almost any biomass. It is conceivable that nanocellulose membranes developed from inexpensive, abundant, and sustainable resources (such as agriculture residues and underutilized biomass waste) can lower the cost of membrane separation, as these membranes offer the ability to remove a range of pollutants in one step, via size exclusion and/or adsorption. The nanocellulose‐enabled membrane technology not only may be suitable for tackling global drinking water challenges, but it can also provide a new low‐cost platform for various pressure‐driven filtration techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Some relevant parameters that can control the filtration performance of nanocellulose‐enabled membranes are comprehensively discussed. A short review of the current state of development for nanocellulose membranes is also provided.

用于水净化的纳米纤维素膜：前景

膜技术仍然是从水中去除污染物（微米级颗粒至埃级水合离子）的最节能方法。但是，当前的膜技术，涉及相对昂贵的合成材料，对于社会上最贫穷的社区来说往往是不可持续的。在本文中，将对基于纳米纤维素纤维的新兴纳米纤维素膜技术提供观点，这种纤维素可以从几乎任何生物质中提取。可以想象，由廉价，丰富和可持续的资源（例如农业残留物和未充分利用的生物质废物）开发的纳米纤维素膜可以降低膜分离的成本，因为这些膜可通过以下步骤一步一步去除一系列污染物：尺寸排除和/或吸附。启用纳米纤维素的膜技术不仅可能适合应对全球饮用水挑战，而且还可以为各种压力驱动的过滤技术（例如微滤，超滤，纳滤和反渗透）提供新的低成本平台。全面讨论了一些可以控制纳米纤维素膜过滤性能的相关参数。还简要概述了纳米纤维素膜的当前发展状况。全面讨论了一些可以控制纳米纤维素膜过滤性能的相关参数。还简要概述了纳米纤维素膜的当前发展状况。全面讨论了一些可以控制纳米纤维素膜过滤性能的相关参数。还简要概述了纳米纤维素膜的当前发展状况。
