Feasibility of three concepts for oil-in-water content monitors developed under separate Coast Guard contracts is described. The three methods-oil fluorescence synchronous scanning, light scattering at ninety degrees ratioed against light transmission, and small angle forward light scattering ratioed against light transmission - allow the breadboard monitors to measure oil linearly over the range of 0 to 100 ppm when oil type is known. Also, a second phase feasibility study is described. The work includes: modifying the monitors to improve their sensitivity and selectivity to oil, thus reducing the envelope of curves due to different linear responses to different oil types, and reducing background bias due to particulates or varying water conditions; resolving areas of uncertainty that came to light during the first phase; and demonstrating the instruments' capabilities and limitations in monitoring the effluent from an oily water separator.
