ABSTRACT:
An improved method of operating a membrane separation system is provided, which comprises applying a reduced pressure to one side of the or each membrane to thereby cause fluid to be drawn through the or each membrane from the other side thereof.
As the method does not utilize fluid under pressure, which has typically been required in prior art procedures, the risk of damage to the membranes is eliminated, or at least minimized.
