<p>Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules [10] have a module case [C] and at least one pair of superposed fabric sheets [12,14] disposed within the case [C], the fabric sheets being pleated and nested in the lengthwise direction of the case. Each fabric sheet [12,14] contains warp-wise extending hollow fiber membranes [Ff, Fs]. The hollow fiber membranes [Ff] within the folds of one fabric sheet [12] will therefore form alternating rows with the hollow fiber membranes [Fs] within the folds of the other fabric sheet [14] by virtue of the length-wise nested pleating. As a result, the effective membrane thickness value of the module is minimized thereby enhancing the efficacy of fluid separations. <IMAGE></p> |
