ABSTRACT:
An oil-contaminated water stream is monitored by continuously exciting and measuring fluorescence in the stream at a monitoring point and producing a continuous monitoring indication accordingly, recurrently withdrawing from the stream samples of the contaminated water, determining the oil content of each sample by an infra-red absorption procedure, comparing each oil determination with the monitoring indication pertaining to the appropriate part of the stream and correcting or recalibrating the monitoring indication accordingly.
