Membrane-based filtration technologies are standard separation processes and are widely used in water treatment; however their performance is still severely limited by the membrane thickness. This project combines the cutting-edge technologies of membrane fabrication and the science of atomic layer materials, graphene, to realize high-performance graphene hollow fibre membranes for desalination of seawater and wastewater treatment. We will develop graphene membranes supported by metal hollow fibre substrates where the thickness of the graphene membrane layer will be less than 5 nm with controlled pore size from 0.3 to 20 nm. The graphene hollow fibre membrane will overwhelm other membranes with the same pore size by at least fifty times higher permeation flux. Furthermore, in this project we will assemble membrane modules of above graphene hollow fibre membranes and build a lab-scale demo plant to evaluate its feasibility in real applications. A set of methodologies and knowledge of preparing graphene hollow fibre membranes and membrane modules will be developed for the first time, making graphene in a real engineering application.

基于膜的过滤技术是标准的分离过程，并且广泛用于水处理;然而，它们的性能仍然受到膜厚度的严重限制。该项目结合了膜制造的尖端技术和原子层材料石墨烯的科学，以实现用于海水淡化和废水处理的高性能石墨烯中空纤维膜。我们将开发由金属中空纤维基底支撑的石墨烯膜，其中石墨烯膜层的厚度将小于5 nm，具有0.3至20 nm的受控孔径。石墨烯中空纤维膜将超过具有相同孔径的其他膜至少50倍高的渗透通量。此外，在本项目中，我们将组装上述石墨烯中空纤维膜的膜组件，并建立一个实验室规模的演示工厂，以评估其在真实的应用中的可行性。首次开发出一套石墨烯中空纤维膜和膜组件的制备方法和知识，使石墨烯在真实的工程应用中得以实现。
