Coupling fluid separation membrane elements.

摘要

An improved method is disclosed for coupling membrane elements of a fluid separation module in series. The improvement comprises providing flexible coupling members having two open ends and a passage between said ends; and securing the first end of a coupling member to the residual end of each membrane element (with the optional exception of the last in the series) and securing the second end of the coupling member to the feed end of the next membrane element in the series if any. Fluid from the residual end of each membrane element except the last may thus be directed to the feed end of the next membrane element. An improved fluid separation module employing such couplings is disclosed; as is an improved membrane element having a coupling member secured thereto.
