Abstract
A backflush fluid line is configured to provide a backflush fluid, under a pressure, to a filtration membrane of an encapsulated filtration vessel. A control subsystem can be used to assist in determining when the vessel should be backflushed, and a plurality of valves can cooperate to switch between a filtration mode and a backflushing mode. In preferred embodiments the backflush fluid line can be configured to provide at least some of the backflush fluid to the vessel via the permeate port, and debris fluid exits the vessel via the feed fluid inlet port. Three-way valves are preferably used to control the fluid flows.
