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.

工程渗透(EO)基于自然渗透原理，是一种新兴的低能量海水淡化技术和压力缓速渗透发电技术。然而，这一过程受到目前使用的膜所经历的内部浓度极化(ICP)效应的挑战的限制。因此，本项目的目的是加深我们对电氧化过程中的ICP现象的了解，并评估通过在薄膜复合EO膜中加入创新的功能化纳米纤维支撑层来缓解ICP效应对EO过程性能影响的策略。预计水通量和机械强度将显著增加。
