Recently, high rate filtration, (filter rates in excess of 3 gpm/sq. ft.), with mixed media filters, (as opposed to single media sand filters), has been found successful in water treatment. To determine the feasibility of utilizing high rate filtration, water quality must be monitored, analyzed, and compared to existing water quality standards to determine if high rate filtration is deleterious to filtrate quality. This study evaluates the use of high rate filtration with mixed media filters using Lake Michigan water. The study was undertaken at the City of Oak Creek Water Treatment Plant on a full scale basis. Two of the plant's four filters were monitored. One filter was run continuously at 3 gpm/sq. ft., (presently the maximum filter rate allowed by the Wisconsin Department of Natural Resources), and the other filter was randomly run at filter rates of 3.O to 6.0 gpm/sq. ft. in intervals of 0.5 gpm/sq. ft.
