Gravity liquid filtration apparatus with rotatable discs that mount swinging discharge elements therebetween

A gravity liquid filtration apparatus which comrpises

• a frame means having opposite side walls and providing an open bottom,
• a pool-forming means mounted between said opposite side walls, said pool-forming means including a central shaft, two spaced apart containment discs rotatably mounted on said central shaft, said containment discs having peripheral edges, and two mounting brackets respectively mounted to corresponding locations on facing sides of said two containment discs, each mounting bracket including a swing pin extending toward the other containment disc, and a discharge element mounted on and between said swing pins, said discharge element including a contact rod which can contact a run of an endless carrier belt which is pressed against the peripheral edges of said two containment discs,
• a filter medium supply means which includes an elongated filter medium and which is capable of discharging said elongated filter medium therefrom,
• a filter medium carrier means for supporting said elongated filter medium and for pressing it against the peripheral edges of said two containment discs along corresponding bottom arcs thereof, said filter medium carrier means comprising an endless wire belt and a plurality of rollers which support said endless wire belt such that a run thereof is pressed towards said peripheral edges of said containment discs,
• a drive means for driving said filter medium carrier means, and
• a liquid input means, said liquid input means including a delivery head having a nozzle portion which extends between and radially inwardly of the peripheries of said two containment discs, said nozzle portion having an elongated mouth which is aimed downwardly so as to discharge liquid to be filtered onto a downwardly sloped portion of the filter medium supported on said filter medium carrier means.
