Disposal of rejected brine from seawater reverse osmosis desalination plants causes major pollution problems and existing solutions are expensive. Recovery of valuable metals such as rubidium (Rb) after further concentration of the brine will lead to environmental and economic benefits. This project aims to develop a novel electrospun nanofibre membrane distillation membrane to economically concentrate the brine and to develop novel adsorbents and desorbents to recover the valuable Rb. It is expected that the concentration and recovery of Rb will lead to a sustainable way of handling the brine, as the concentration cost can be offset by the selling of Rb.

从海水反渗透淡化厂排出的废盐水的处理造成了严重的污染问题，现有的解决方案价格昂贵。在卤水进一步浓缩后，回收有价金属如铷（Rb）将带来环境效益和经济效益。本项目旨在开发一种新型电纺丝纳米纤维膜蒸馏膜，以经济地浓缩卤水，并开发新型吸附剂和解吸剂，以回收有价值的Rb。预计Rb的浓缩和回收将导致一种可持续的卤水处理方式，因为浓缩成本可以通过出售Rb来抵消。
