Abstract

1,171,259. Filter bed. L. & C. STEINMULLER G.m.b.H. 25 Oct., 1968 [28 Oct., 1967], No. 50791/68. Addition to 1158730. Heading B1D. Liquids are filtered in a container in which the inert granular bed of gravel sand or coke is flushed or regenerated by an offtake system in reverse direction to the filter flow. During the upward expansion of the bed during flushing or regeneration gas pressure is directly exerted on the surface of the bed and is controlled so that the level of liquid discharged through the offtake system is maintained at or just below the surface of the bed.
