Abstract

1513737 Cleaning filters ALCAN RESEARCH & DEVELOPMENT Ltd 18 Aug 1975 [23 Aug 1974] 37285/74 Heading BID The inward flow flat (or annular) filter leaves 6 are periodically cleaned by liquid sprayed from rotating spray bar 19 which has a discharging slit extending the length of the bar, the wash liquid being discharged via means 14 which also acts as inlet for liquid to be filtered. Each filter leaf may comprise a woven bag supported on a frame and layers of woven wire, the frame being the outlet for filtrate. The leaves may discharge filtrate into a manifold 15 located outside or inside the housing 1.
