ABSTRACT:
A spirally wound membrane module and membrane system containing a plurality of modules in series which spirally wound membrane module includes a low pressure drop mesh spacer material composed of generally parallel elongated filaments positioned generally parallel to the flow direction of the feed stream and wherein the elongated filaments are connected by shorter bridge filaments which are placed at an angle to the flow of the feed stream to provide for a low pressure drop, spirally wound membrane module and which permits such module to be employed in series without exceeding a defined maximum, allowable pressure drop.
