Abstract: A vertical vessel has a filter bed disposed in its lower portion for normal filtering of solid particulates from contaminated liquid passed down through the bed. Vertical passages are formed to extend below the upper surface of the filter bed with a layer of smooth-surfaced bodies arranged to reduce the cross-sectional area of the vessel to impart desired velocity to the particulates in the liquid. Conduits are provided to flow liquid and gas up through the bed to backwash particulates from the bed into a collection above the bed which is removed by a siphon in a batch operation.
