Tank Dewatering System: Monitoring low ppm oil in water

Above this free water layer at the base of the storage tank is a so called ‘’rag layer’’ consisting of an oil-water emulsion. This rag layer has different optical properties than that of the free water below it or the hydrocarbon above it, so the detection of this rag layer can be used to ensure complete water removal and reduce the amount of hydrocarbon drained from the tank.
