ABSTRACT:
A filter device useful in continuous separation of solid matter from a liquid, such as liquid wastewater, where the filter includes a tubular filter element with a series of slots of selected width extending through the tubular element. The filter element has a longitudinally extending central opening with a fluid inlet therein and is received in a first tubular casing with an annular area defined between the tubular filter element and the first casing so the central opening is open to receive liquid to be filtered, liquid being filtered as the liquid flows outwardly through the slots from the central opening to the annular area. A seal is provided between the tubular element and the inside of the first casing at a location below the slots in the tubular element to prevent unfiltered wastewater from entering the annular area. A second tubular casing is provided which extends downwardly beyond the lower terminating end of the tubular filter element, the second tubular casing including flow-through openings or slots therein for the passage of liquid therethrough. The second tubular casing flow-through openings are in flow communication with a fluid inlet into the central opening of the filter element.
