  • Patent number: 7494591
    Abstract: Systems and methods convey the blood through a gap defined between an inner surface that is located about an axis and an outer surface that is concentric with the inner surface. At least one of the inner and outer surfaces carries a membrane that consists essentially of either a hemofiltration membrane or a hemodialysis membrane. The systems and methods cause relative movement between the inner and outer surfaces about the axis at a selected surface velocity, taking into account the size of the gap. The relative movement of the two surfaces creates movement of the blood within the gap, which creates vortical flow conditions that induce transport of cellular blood components from the membrane while plasma water and waste material are transported to the membrane for transport across the membrane. Shear-enhanced transport of waste materials and blood plasma water results.

  • Patent number: 7399419
    Abstract: A filter system includes a set of modules, each module including screen assemblies and filter media sandwiched between the screen assemblies. A plurality of control assemblies are associated with each of the modules. Each of the control assemblies is in fluid communication with a corresponding module to control flow through the corresponding module. The control assemblies selectively control fluid in each of the modules between at least one of a forward flow through the screen assemblies to treat an influent flow, a bypass flow to bypass at least one of the modules, and a reverse flow to backwash a given filter media. A method of filtering influent includes providing an influent flow to a set of modules, each module including screen assemblies and filter media sandwiched between the screen assemblies. The influent is filtered by directing the influent through the set of modules. A given module is bypassed when the given module becomes occluded.

  • Publication number: 20080116125
    Abstract: A filtering apparatus having two distinct filter media for filtering circulating fluid in a circulation system. A portion of the fluid entering the filter passes through a first filter media, while a reduced portion of the fluid entering the filter passes through a second filter media. The second filter media accumulates contaminants and suspended particles from the circulating fluid. The filter media is capable of including at least one additive for treating the circulating fluid. Due to the reduced volumetric fluid flow through the second filter media, the additive can be slowly administered to the circulating fluid over a long period of time. The two filter media may be housed in a dual-canister, where the second filter media may be removed and replaced without removing the first filter media.

  • Patent number: 6811694
    Abstract: A liquid filter for removing contaminants from liquids such as lubricating oil, water or fuel, comprising a filter housing (10), a filter element (15), a support body (16) and a slide valve (17), which, when closed, prevents liquid from flowing from an unfiltered liquid area or from a filtered liquid area to a filter outlet (24). When the filter housing is opened, the slide valve moves axially and opens the filter outlet (24) so that the filter housing can empty. The slide valve (17) is detachably snapped together with the support body (16), which in turn is connected to a housing cover (12). This enables the slide valve to be detached from the support body, and reduces the level of maintenance required by the liquid filter.
