Abstract

120,867. Wilson, J. Aug. 9, 1918. Filters with loose filtering - materials. - Relates to arrangements for supplying water to a filter of the type in which water is filtered upwards through a bed of sand and gravel, and for washing t h e filtering- medium. The feedpipe h opens into a dome i with a serrated lower edge placed under the filtering-medium. The dome i is provided with an air-vent pipe k. An escape valve l is arranged by means of which water can be drawn off downwards through the filtering-medium, to cleanse it, at the same time entraining air through a pipe q. The valve l and a valve r on the pipe q are then closed, and water is introduced below the medium through a pipe s, forcing the air up through the medium and cleansing it further. The washing-water escapes by a pipe t.
