Abstract

A novel optical sensor equipment has been developed for the measurement of total suspended solids TSS concentrations. The sensing equipment makes use of light-emitting diodes, LED's, as sources, and a silicon photodiode as a detector. The photodetector detects light scattered at 90°. The signal was correlated with the measured TSS concentrations. Scattered light was measured in terms of the output voltage of the photodetector of the proposed optical system. The output voltage was read using a conventional voltmeter. The correlation coefficient produced was high and the root mean square error was low.
