Abstract

One of the main problems when using membrane for water treatment is fouling. Several parameters have been proposed for measuring the fouling potential. Up to now, the SDI (Silt Density Index) and the MFI0,45 (Modified Fouling Index) are used but they did not reflect the real potential of fouling. In fact particles smaller than 0,45 µm responsible of fouling are not taken in consideration. In this work, an improvement of the determination of fouling index is proposed by using NF membrane and strictly defined working conditions (constant transmembrane Pressure).
