ABSTRACT:
A bed of particulate material of varying sizes is located within a vessel. This bed comprises an upper and lower region. Particulate material is supplied continuously to the center of the upper region so as to form a peak shape which descends downwardly and radially outwardly from the center. Liquid to be filtered is introduced to this peak shape and is filtered downwardly through the bed. A majority of the filtered liquid passes through a screen located between the upper and the lower regions into a screen filtrate enclosure. The remaining liquid continues to the lower region. This liquid and dirty particulate material are transported by an air lift tube from the lower region to a position above the upper region. At this position, the particulate material is washed and supplied to the center of the upper region. The remaining liquid and filtered particles are removed from the vessel.
