ABSTRACT:
A filter device used to remove organic and inorganic debris from a liquid stream, such as irrigation water. The device comprises a diverter tube having a plurality of apertures therein to divert a significant portion of the liquids entering the device onto a filter screen, thereby filtering out the lighter debris on the screen. A portion of the liquid flows through the diverter tube with the heavier debris entrained therein, which settles out by gravity in a dead water zone at the lowermost end of the device. A flush valve can be opened, permitting the heavier debris to be swept out, and back-flushing the lighter debris off of the filter screen.
