Abstract
A self cleaning filtration device wherein an activation piston, laterally supported within an activation cylinder is immersed in filtrate within the confines of an immersion chamber. The immersion chamber receives filtrate from a disk filtration stack via orifices and sparger support tubes (the 'Tubes'). Gas pressure (i) drives the piston, the Tubes, and the disk compression block upward and (ii) forces the immersion chamber fluid through the Tubes to separate the disks. The Tubes contain gas entrainment orifices on the side of the piston that are configured to facilitate entrainment of gas into the fluid. The entrained fluid impacts the opened disks with a high energy dispersed scouring action, to flush the disks clean.
