Abstract

462,463. Filters. BROOK, E. P. Aug. 7, 1935, No. 22260. [Class 46] The filter bed b, Fig. 1, of sand, gravel, or the like is provided with a perforated ring pipe l near to the filter wall for supplying air under pressure to agitate the medium as well as with the usual network of perforated pipes e through which the filtrate is discharged and air and water supplied in reverse direction to agitate and cleanse the medium. The air may be supplied to the pipes l, e through valves n, i respectively from a pipe h. Fig. 4 shows a filter of rectangular plan with air supply pipes el, e<2> along either side.
