Abstract

"In spite of the importance of the carbon adsorption method (CAM) in determining drinking water quality and its wide use in research and plant control studies, little work has been undertaken to quantitatively and qualitatively evaluate the method, especially under field conditions. This investigation was, therefore, undertaken in order to develop a test system consisting of equipment and procedures which would make possible the field evaluation of the carbon adsorption method by parallel solvent extraction studies, and to employ this system in preliminary field investigations to establish guidelines for the experimental conditions required for its effective application. The test system developed in this study consisted of a sand filter and four carbon filters connected in series; a raw water pump; an acid storage tank and acid pump; sample outlets and storage reservoirs located before and after each filter unit; and associated flow meter, pressure gage, valves and piping. Organic micropollutants were recovered from a subsurface water source (Maramec Spring) by carbon adsorption at the natural (7.1) and an adjusted pH ( 2. 5) and were eluted from the carbon with chloroform and benzene. Raw water and filter effluent samples, composited over appropriate periods, were solvent extracted with chloroform and benzene at appropriate pH levels (7.1, 2.5, and 10.0). The test system proved to be satisfactory for the field evaluation of the CAM and enabled the monitoring of the trace organics in the influent to and effluent from the carbon filters. Preliminary evaluation studies indicated that the CAM had a low total efficiency for recovering trace organics, however, further research is needed in order to fully evaluate the method and establish its limitations"--Abstract, page ii.
