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.

Hollow fiber membrane module for direct contact membrane distillation-based desalination

A modular fluid treatment system utilizing hollow fiber cartridges held within the controlled environment of a reaction chamber, with the system being designed to accommodate and facilitate ease of access to individual cartridges within a given module. The arrangement provides for parallel operation of a group of individual modules, while at the same time facilitating access to individual modules for cartridge replacement. Each module includes an elongated cylindrical reaction chamber with end caps, with the end caps being designed to sealingly engage and retain individual cartridges for use within the module, while at the same time providing for accommodating a wide range of tolerance for variations in cartridge length.
