<p>A filter backflushing system including an accumulator containing a pressurized bladder which propels a supply of backwash fluid contained within the accumulator in a reverse direction through a filter element. While the backwash fluid is pumped within the accumulator, an inert gas inside the bladder is compressed against the inside walls of the accumulator. Upon reaching a pressure of approximately 300-600 psi, the filtered fluid is released from the accumulator and the full energy of the compressed gas is released as well. This release produces a high pressure rapid burst of backwash fluid which effectively removes clogging contaminants from a filter element.</p> |
