Abstract

Methods and devices for real-time detection of fouling chemistry are described herein. In one aspect, a method of detecting and characterizing fouling of a membrane used for separation in a fluid-based system can include illuminating the membrane with one or more light sources, collecting Raman spectroscopy data from the membrane, and based on the Raman data, determining at least one selected from the group consisting of: presence or absence of membrane fouling, severity of membrane fouling, and composition of the membrane fouling, where the Raman spectroscopy is selected from the group consisting of Coherent Anti-Stokes Raman Scattering (CARS), Stimulated Raman Scattering (SRS), and spontaneous Raman Scattering.
