Abstract
971,338. Percolating-filters. ALBRIGHT & WILSON (MFG) Ltd. Nov. 2, 1962 [Aug. 11, 1961], No. 29069/61. Heading BID. Effluent flows downwards for bacterial disposal through a filter bed consisting of particles of average diameter 1/16 inch to <SP>1</SP>/ 4 inch and of specific gravity 1 to 2 and the bed is periodically cleaned by interrupting the flow of effluent and passing a fluid through the bed in reverse direction at a rate to fluidize the bed. Untreated effluent introduced at 23 and 18, with optional addition of re-circulated effluent from a pump 13, enters space 14 and with compressed air introduced at 17 passes downwards through a bed 10 to a space 15. It passes thence to a vessel 16 where air escapes and the liquid is discharged as outflow or passes to recirculating pump 13. To clean the bed according to one method, valves 17-19 and 23 are closed and a valve 20 is opened to permit effluent to be fed for distribution at 15 ; alternatively a valve 21 is opened for introduction of water. In either case the liquid passes upwards, the free space 14 permitting the expansion of the bed occasioned by the upward flow. The liquid leaves at 22 and is either re-cycled or discharged from the vessel 16. Preferably a positive air pressure is maintained above the bed. An alternative method of cleaning consists in interrupting the flow of effluent from the bed instead of reversing it ; the bed then fills up with effluent, and air is then blown through it from the bottom to disturb the particles. The preferred bed material is coke, but foamed slag or polystyrene may be used. It is stated to be known to supply a pure liquid under pressure for backwashing to perforated pipes arranged vertically in a trickling filter composed of very fine cinders. Later, air is fed under pressure through another similar set of pipes located between the others. Thereafter the soiled liquid is allowed to rise above the filter bed level and is led away.
