ABSTRACT:
A membrane separation process and system for removing a component from a fluid stream. An auxiliary membrane module or set of modules is installed across the pump that drives the main membrane unit, so that the permeate streams from the main and auxiliary membrane units are mixed and pass together through a common driving pump. The concentration of the mixed permeate stream is allowed to build up by circulating the stream through the auxiliary unit. When the concentration has reached a desired level, the mixed stream can be tapped and the product stream drawn off.
