1. A multiple membrane separation system, which comprises:
- (a) a plurality of discrete membrane separation units, each membrane separation unit comprising at least two membranes, an inlet for process fluid and, optionally, an outlet for process fluid;
(b) means for locating said membrane separation units within a container for permeate, said container comprising a permeate outlet, and wherein the container enables the membrane separation units to be at least partially immersed in permeate; and
(c) a conduit means to enable reduced pressure to be created at the common process fluid inlet and/or the common process fluid outlet of the membrane separation units and thereby resulting in fluid being drawn through the membranes from the permeate side thereof to the process fluid side thereof.
