Beschreibung
Zusammenfassung:	The present invention provides an apparatus including: a filter medium having a slack state and a ballooned state and an elastic support attached to the filter medium to define a contiguous fluid flow path through the filter medium and the support. The elastic support is adapted to displace the filter medium repeatedly between the slack state and the ballooned state; the ballooned state is out-of-plane with respect to the slack state; and the slack state of the filter medium provides for areal strain greater than about 10% of the ballooned state. A method of cleaning a filter medium in a flow path of a fluid containing a suspended component is also described.
