Developmental oil-content monitors for shipboard use are being evaluated at the David Taylor Naval Ship Research and Development Center, Bethesda, Md. The monitors, which are one element of the Navy's shipboard oily waste treatment system, analyze and control the discharge of treated effluent from oil-water separators, the primary element of the treatment system. Oil-content monitors under development are being designed to reliably analyze the level of oil remaining in the waste stream on a real-time basis. Specifically, the monitors compare the oil content of the waste stream with applicable discharge standards and automatically recycle unacceptable effluent while allowing the discharge of clean water. Major problems encountered in monitoring shipboard wastes include the fouling of optical windows and inaccurate measurements caused by particulates and detergents in the waste stream. To overcome these problems, prototype monitors being evaluated utilize light scattering/transmission, ultraviolet fluorescence, and solvent extraction/infrared absorption technologies.
