Membrane fouling is formed due to pore blocking and cake formation by suspended material or contaminant in the membrane boundary layer. Membrane fouling is main obstacle for the wider application of industrial water treatment. The objective of this paper is to study the direct monitoring technique for the measuring the membrane fouling in real time. We investigated the extracted image of R, G, and B by visible light irradiation of 360 nm wavelength to measure the membrane fouling in real time by transparent foulant. The intensity of B of 400~499 nm wavelength range was stronger than that of R and G. The fluorescence image extraction analysis appeared to be a very attractive technique for monitoring the membrane fouling in real time.
