Title:
FOULING PREDICTION METHOD, AND MEMBRANE FILTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/124538
Kind Code:
A1
Abstract:
A fouling prediction method in a membrane filtration system for filtering raw water containing ions and salt components, the method involving a step for irradiating raw water before being filtered by the membrane module with excitation light of a plurality of different wavelengths, a step for measuring the fluorescence intensity of fluorescent light generated by irradiating excitation light of a plurality of different wavelengths, and a step for predicting the occurrence of fouling by using a coefficient set for each wavelength range of the fluorescent light and the value of the measured plurality of fluorescence intensities.
