Engineered osmosis (EO) is based on the principles of natural osmosis and is an emerging technology for low energy desalination and power generation by pressure-retarded osmosis. However, the process is limited by the challenge of the internal concentration polarisation (ICP) effects experienced when currently available membranes are used. Therefore, the aims of this project are to enhance our understanding of the ICP phenomenon in EO process and to evaluate strategies to mitigate the influence of ICP effects on the performance of the EO process by incorporating innovative functionalised nanofibrous support layers for thin-film composite EO membrane. A significant increase of water flux and mechanical strength is anticipated.
