  • Filtering methods and configurations
    Patent number: 8741137
    Abstract: Passing a fluid though a single filter module effectively removes at least two different types of impurities from the fluid. The fluid is directed through at least two different types of filtering media within the single module. The at least two different types of filtering media are separated from one another, within the single module, by a porous containment layer of the module; and, one of the at least two different type of filtering media forms a core of the module, which is surrounded by the porous containment layer.
