Abstract

521,676. Filters. GRIFFIN, J. D. Nov. 24, 1938, No. 34253. [Class 46] A biological filter has its upper portion enclosed by a gastight casing 5 and cover 6, while the lower portion is open at its sides so as to be in direct communication with the atmosphere. As shown the casing is supportedon pillars 4 and a retaining wall around the lower part of the. medium is formed by larger blocks 14 of the medium. An outer-ring of the bed made air-tight by treatment with cement may take the place of the casing 5 or of part thereof. As shown air is drawn into the casing bya fan 10, driven by an electric motor 12 which also drives a [sprinkler 7 to which the liquid is supplied by a pipe 8.
