Feed-and-Bleed

An ultrafiltration term borrowed from old-fashioned boiler operators. When applied to an ultrafilter design, it means multiple stages of ultrafilter units where the feedwater is controlled at a rate equal to the permeate plus concentrate flow rates and the reject water from the initial ultrafiltration stages is recirculated to subsequent stages.
