Monitoring Desalination Membrane Fouling using Sodium Magnetic Resonance

膜组件海水淡化是获取饮用水的关键技术，但由于污染，海水淡化面临着巨大的挑战。将开发钠磁共振技术，以非侵入性地检测和成像这些不透明膜组件中因污染而积累的盐分。这些数据将首先用于改善我们对模块中污垢和有害盐分积累(称为滤饼增强浓度极化)之间尚未探索的相互作用的理解，从而验证对这一现象的3D模拟。然后，明确检测膜组件中盐积累的能力将被推断为海水淡化设施中膜污染的非侵入性监测工具。

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.
