Abstract: An apparatus and method to perform multiple filtration steps with a modular filtration apparatus and single cycle. A stackable modular filter cup has features to allow stacked cups to be separated without the need for substantial effort yet without diminishing the effect of vacuum assisted filtration. Each cup is formed with a slip seal segment and/or a series of substantially vertical channels or ridges on an inner or outer wall to reduce surface contact between nested filter cups.

Abstract: An apparatus for the transfer of mass and heat including a membrane having a hydrophilic surface and an opposing hydrophobic surface. The construction prevents transmission or leakage of fluids from one side of the membrane to the other regardless of pressure gradients within the membrane bubble point or water intrusion pressure range, but allows the transfer of vaporized fluid from one side of the membrane to the other.

Abstract: A depth filter design is disclosed which has little if any open void area upstream of the media. Preferably, it also has little if any open void area downstream of the media as well. A preferred embodiment uses layers of stacked, fibrous media with several of the layers being separated from the others by spacers which serve to compress the media and to prevent the bypass of fluid around the media adjacent the inner wall of the housing. Several designs for attaching the end caps which allow for the compression of the media are also disclosed.

Abstract: Disclosed is a disposable filter capsule apparatus that incorporates integral quick connect components and check valves to facilitate assembly to, and dis-assembly from, larger assemblies and apparatus. The quick connect elements and valves are configured to eliminate the need for auxiliary sealing elements, e.g., o-rings and valve springs so as to prevent unwanted reactions with fluids and/or gases flowing through the capsules, and to further prevent the disposal of expensive re-usable elements in the disposable capsules.

Abstract: Disclosed is a capsule apparatus having a filter housing defining a filter chamber with a top cap having a plurality of ports extending substantially laterally from a top end of the top cap to reduce the overall dimensions of the apparatus. The lateral and substantially uniform orientation of the ports facilitates connection to panel mount assemblies and improves filter maintenance processes. A transfer tube extending the length of the capsule allows the introduction of heated fluids from a top mounted inlet port to a bottom of the capsule chamber to allow or a substantially uniform heat gradient in the capsule filter chamber. An alternative shield secured in the housing defines a first chamber in fluid communication with an inlet and a second chamber wherein the two chambers are in fluid communication via an opening defined by a lower end of the shield and a bottom of the filter chamber.

Abstract: The liquid recovery filter includes several embodiments, each of which provides for the recovery of liquid otherwise trapped within the filter housing and element. Each embodiment includes a series of vents, purge ports, and passages that communicate fluidly with the filter housing and filter core. Certain vents and purge ports are initially opened following filtration operations to allow pressurized gas to flow into the housing, thereby forcing residual unfiltered liquid through the filter. When this has been accomplished, another vent is opened to the filter core to allow filtered liquid to flow from the downstream or outlet passage from the filter core. Some embodiments have the filter outlet located above the filter, and include a downstream drain port extending from the filter core. The downstream drain port provides for the recovery of filtered liquid when the vent or purge port is opened in these embodiments.
