The objective of the study is to evaluate on a laboratory and pilot field scale the performance of the intermittent sand filter as a polishing process that would upgrade existing wastewater treatment facilities. Particular attention was directed toward ascertaining the effectiveness of the intermittent sand filter as a means of removing the highly variable quantities of algae present in stabilization ponds during the warmer months of the year. These results will be used to develop design criteria for intermittent sand filters that would consistently produce an effluent of a quality that would meet stringent water quality standards.
