  • Filter with counter flow clearing
    Patent number: 6354442
    Abstract: A filter system (10) comprising a filter medium (11) for filtering contaminants from a process fluid, having a filtration side on which contaminants collect and a filtrate side from which filtrate flows; a counter-flow generator (20) located on the filtrate side that directs a localized stream of counter-flow fluid (23) from the filtrate side to the filtration side of the filter medium (11) to thereby dislodge the contaminants from the filtration side of the filter medium (11), wherein the localized stream (23) traverses a substantial proportion of the filter medium (11). The filter system (10) optionally further comprises a clearing-flow generator (30) or like means located on the filtration side of the filter medium (11) which clears contaminants from the filter medium (11).
