摘要： Exemplary embodiments in desalination by direct contact membrane distillation present a cylindrical cross-flow module containing high-flux composite hydrophobic hollow fiber membranes. The present embodiments are directed to a model that has been developed to describe the observed water production rates of such devices in multiple brine feed introduction configurations. The model describes the observed water vapor production rates for different feed brine temperatures at various feed brine flow rates. The model flux predictions have been explored over a range of hollow fiber lengths to compare the present results with those obtained earlier from rectangular modules which had significantly shorter hollow fibers.

摘要： A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

摘要： A cartridge is provided for dialysis or other blood processing therapy. In the cartridge, fibers may be substantially uniformly distributed near a midplane, but near an end, in the inter fiber space, there may be void flow channels, which may cause fluid flow in the inter fiber space to transition within a short region to uniform flow with minimal stagnation zones. Void flow channels may be be radially oriented, introducing fluid from the outer circumference, or axially oriented, introducing fluid along the axial direction through passageways through the potting material. The fluid flow in the inter fiber space may be perpendicular to the fibers, or radial with respect to a cartridge longitudinal axis. The cartridge may have blood flow in the inter fiber space, and flow of dialysate or ultrafiltrate in the lumens of the fibers, or the opposite situation.

摘要： A CMS membrane module includes plurality of hollow fiber CMS membranes that are enclosed within an open cylindrical shell whose ends are embedded in tubesheets. The shell is concentrically disposed within an open cylindrical pressure vessel whose open ends are covered by and secured by end caps. The shell includes a feed fluid inlet formed therein between the tubesheets and a retentate outlet in between one of the tubesheets and an adjacent end cap. A retentate seal is formed between the shell and the pressure vessel at a position between the tubesheets. A permeate seal is formed between the pressure vessel and the tubesheet that is adjacent a permeate port of the module. A structure made up of the CMS membranes, shell, tubesheets, and seals is slidable within the pressure vessel and not fixed in place in relation to the pressure vessel and end caps.
