ABSTRACT:
The present invention relates to an improved design for a moving liquid membrane module. In one embodiment, the tubular or hollow fiber module, at least one tubular or hollow fiber element is contained within a housing. This element comprises an inner tubular membrane and an outer tubular membrane. The element comprises a first tubular membrane located within a second tubular membrane of larger diameter. The membrane liquid is continuously passed through annular gap between the two tubular membranes. The feed fluid is continuously passed through the lumen of the inner tubular membrane and the purge or strip fluid is continuously passed over the outer surface of the outer tubular membrane. In a second embodiment, the spiral wound moving liquid membrane module, a spiral wound cartridge is incorporated into a housing. The cartridge is formed by wrapping at least one permeant depletion channel, one permeant enrichment channel and one membrane liquid channel around a core tube. The permeant enrichment and depletion channels are sealed by adhesives and the fluids flowing therein may be counter-current or cocurrent with respect to each other. Membrane liquid is continuously passed between the permeant depletion and enrichment channels which are wound around the core tube, thereby, creating a counter-current or cocurrent flows between the membrane liquids and the liquids flowing in the permeant depletion and enrichment channels.
