    摘要: Hollow fibre membrane modules (1) with a shell-side configuration often comprise a hollow fibre bundle (2) and a perforated hollow internal core (4) inside the bundle. A plug (5) in the core and a baffle (15) in the bundle are typically employed in order to desirably distribute supplied fluid over the bundle for separation purposes. The fluid flow distribution can be improved by incorporating suitable flow distributors (20, 21) within the internal core itself. Such modules are particularly useful for osmotic membrane distillation.

    摘要: Embodiments of the present invention provide replacement of conventional separate feed spacer mesh with features placed, deposited or integrated on or into either the porous permeate carrier, the inactive side of the membrane sheet, or select portions of the membrane surface. Spiral-wound membrane filtration elements well known in the art consist of a laminated structure comprised of a membrane sheet sealed to or around a porous permeate carrier which creates a path for removal of the fluid passing through the membrane to a central tube, while this laminated structure is wrapped spirally around the central tube and spaced from itself with a porous feed spacer to allow axial flow of the fluid through the element.

    摘要: A filtration system is provided with filter media operable to remove solids, particulate and colloidal matter from a process fluid. The filtration system may include one or more porous membranes which are anchored or secured on their periphery with a large open work area operable to remove selected components from the process fluid. The filter media may include an envelope formed from two membrane sheets with a spacer element disposed there between. A chamber or collection zone may be formed within the envelope to receive clarified fluid separated from the process fluid. Alternatively, the filter media may be multiple layers of spiral wound membranes or a roll of membranes.
