    Abstract

    On-line instrumentation has performed a significant role in helping Union Carbide protect public waterways from excessive or abnormal pollutant discharges. Instrumentation has been successfully applied to the surveillance of cooling water and process water sewers and to the control of pollution abatement facilities. Although current instrumentation (total carbon analyzer, specific organics analyzer, automatic titrator, foam detectors, etc.) is being successfully applied to a variety of monitoring problems, there are still improvements that are required in the areas of sensitivity, specificity, and reliability. Support hardware (sampling pumps, transfer lines, sample conditioning hardware, and telementry) is also continuing to be improved. While present instrumentation is meeting the needs of today, instrumentation based on new measurement principles (liquid chromatography, biological activity monitors, turbidimeters, etc.) is being currently developed to meet the environmental measurement needs of tomorrow.
