Seawater desalination using membrane modules is critical technology for potable water access, however it faces significant challenges due to fouling. Sodium magnetic resonance techniques will be developed to non-invasively detect and image salt accumulation in these opaque membrane modules due to fouling. These data will first be used to improve our understanding of the unexplored interplay between fouling and detrimental salt accumulation in the modules (known as cake-enhanced concentration polarisation) and thus validate 3D simulations of this phenomenon. The ability to unambiguously detect salt accumulation in membrane modules will then be extrapolated to a non-invasive monitoring tool for membrane fouling in desalination facilities.

使用膜组件的海水淡化是获得饮用水的关键技术，但由于污染，它面临着重大挑战。将开发钠磁共振技术，以非侵入性地检测和成像由于结垢而在这些不透明的膜组件中的盐积累。这些数据将首先用于提高我们对模块中污垢和有害盐积累之间未探索的相互作用的理解（称为蛋糕增强浓度极化），从而验证这种现象的3D模拟。明确检测膜组件中盐积累的能力将被外推到脱盐设施中膜污染的非侵入性监测工具。
