摘要： A microporous hollow fiber membrane device for clarifying and purifying a feedstream. The membranes are capable of forming a shear effect or Dean vortices at their inner surface. The filtrate channel and/or the fibers may contain one or more type of capture materials, such as ion exchange resins, for selectively capturing and retaining certain molecules from the filtrate of feedstream. Alternatively, the capture materials may be kept in a separate chamber or module downstream from filtrate outlet, such as in the recirculation loop. Once the filtration course has run, one or more eluants are run through the capture materials to selectively recover the captured molecules. Optionally, the capture materials are located within the filtrate channel and are used in conjunction with a coflow of filtrate to provide trans-membrane pressure control.

摘要： An apparatus (70) is provided with which a liquid such as an effluent, or output liquid from a bioreactor, can be treated for exmple to remove and concentrate heavy metals or to separate an enzyme. The apparatus incorporates a filtration module (50) and a bed of adsorbent material (80), in an integral unit, the liquid being subjected to cross-flow filtration, and the filtrate being collected in a chamber (52) before being distributed to the adsorbent bed. Fouling of the filter membrane (56) and of the adsorbent material (80) are suppressed, and channelling through the adsorbent bed is prevented.

摘要： Gases are separated or conveyed by surface diffusion using a solid body (28) traversed by extremely narrow passages (34). Because of the relatively high flow resistance due to the extremely small cross-section of the passages, the gas can be conveyed through the solid body (28) almost exclusively by surface diffusion. Consequently, only gases particles (42) adsorbed on the solid body (28) or on the walls of the passages (34) are conveyed through the solid body (28). The surface diffusion can be controlled by suitable choice of the gas/solid body combination. The diffusion is affected mainly by the temperature of the solid body (28). If, in the case of a two-gas mixture, the solid body (28) is heated to a temperature above the desorption temperature of one gas (44) and below the desorption temperature of the other gas (42), only the particles of gas adsorbed on the walls of the passage are conveyed by surface diffusion.
