Title: Solvent filtration system and methods

Abstract: A filter system has a first filter from which solvent is recovered in a cleaning cycle using a rinse fluid in forward flow, and from which particulates are removed using flush gas in reverse flow. At least part of the solvent and the flush gas are recycled to the system, and in still further preferred aspects, filtration of the solvent continues during the cleaning cycle via a bypass circuit through which the solvent is routed to a second filter.
