Development of new type of rapid sand filter
Research program was initiated to design rapid sand filter for water treatment in which media would remain of uniform thickness indefinitely and could be cleaned easily under normal operating conditions, permitting increased filtration rates; tests indicated that system should be hydraulically controlled by orifices in plates at top of filter rather than in underdrain system; conventional wash troughs and surface wash equipment are eliminated by such system; on this basis, 2-ft square unit or "module" was developed and operated as pilot over 3 yr period.
