Abstract
932,537. Filters. M. J. BERARDI. Jan. 18, 1962 [Nov. 30, 1961], No. 1844/62. Class 46. A filter assembly comprises a tank 22 having a closed bottom 26 and an open top, a prefilter head assembly 28 secured to and covering the open top of the tank, a pre-filter bed A comprising three layers of inert e.g. siliceous material in the head assembly, the central layer being of finer particles than are the other layers, a perforated supporting member 70 secured horizontally within the tank for a main filter bed B composed of a mixture of activated carbon particles of various sizes, a draining bed C comprising six layers of inert e.g. pebble material, and a drain conduit 80. A multi-port valve 52 is connected to a source of liquid to be cleaned and to the pre-filter head through a conduit 50 and also to a source of cleaning liquid and to means e.g. a spider 64, comprising crossed conduits 66 perforated in their bottom faces, for introducing the cleaning liquid to the main filter during backflushing, Fig. 6 (not shown), through a conduit 54. Check valves 62 and 82 and a pressure gauge 130 are incorporated.
