Methods of filtering a liquid feed are disclosed. In one version, the method comprises passing a liquid feed through a single pass tangential flow filtration (SPTFF) system and recovering the retentate and permeate from the system in separate containers without recirculation through the SPTFF system. In another version, the method of filtering a liquid feed, comprises passing a liquid feed through a tangential flow filtration (TFF) system, recovering permeate and a portion of the retentate from the system in separate containers without recirculation through the TFF system, and recirculating the remainder of the retentate through the TFF system at least once. The methods can be performed using an SPTFF or a TFF system that comprises manifold segments to serialize the flow path of the feed and retentate without requiring diverter plates.

A humidifier for transferring water vapor from a first gas stream to a second gas stream in a fuel cell system has a stack of thin plates joined together at their edges by planar sealing surfaces, with water permeable membranes between the plates. Each plate defines a gas flow passage along its top and bottom surfaces, with an inlet and outlet defined along edges of the plate, and a flow field extending between the inlet and outlet openings. Inlet and outlet passages connect the inlet and outlet openings to the flow field, with the planar sealing surfaces including bridging portions extending across these passages. Support structures are provided throughout the flow field to support the membrane and diffusion medium layer(s). Each support structure comprises a porous material which is sufficiently porous to permit gas flow through the flow field.

A manifold for domestic water purification systems having flow paths that can be redirected without having to change the physical structure of the manifold or water purification systema structure to assist with proper installation of specific filter cartridges, a memory reader for processing data relating to the state of the filter cartridges, a hinge system to allow for easier installation/removal of new and replacement filter cartridges, and a flow path structure to assist in adding accessories to the water filtration system without requiring a modification to the manifold structure.

An end cap for a filtration module having a chamber includes an outlet channel extending therethrough which is part of or forms an aerodynamically shaped element having a cross section with an elongated shape mainly directed from the inlet to the first outlet, a width of the elongated shape at both ends thereof being smaller than at a center part of the elongated shape. An end cap may also include an inlet, a first and second outlet, and a flow guide element arranged between the inlet and the first outlet within the chamber at a second outlet side thereof, the flow guide element extending a part of an inlet wall to a corresponding part of a first outlet wall, the flow guide element defining one or more openings allowing a portion of a main flow to flow towards the second outlet.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.

The present invention relates to a double pipe and, more specifically, to a double pipe for uniformly distributing a flow, which can distribute as uniformly as possible a flow which should be distributed toward branch pipes thereof. The present invention relates to a double pipe for uniformly distributing a flow, and can be applied to a seawater desalination device or a water purification device using a membrane and can be thus employed in the water treatment plant industry.

The present invention provides for a method for separating starch from processing solutions containing starch containing plants or roots such as potatoes, sweet potatoes, wheat, corn, tapioca, yams, cassaya, sago, rice, pea, broad bean, horse bean, sorghum, konjac, rye, buckwheat and barley to provide commercially acceptable starch while reducing disposal of solid or liquid waste matter into landfills or water treatment facilities.

Assembly for treating fluids, comprising a support (12) having a first and second oppositely arranged surfaces (121) for backing support of a semi permeable membrane (11), a first fluid conveying compartments (124) interposed between the first and second surfaces, a plurality of first fluid passages (126) extending from the first surface (121) and being in fluid communication with the first compartments (124), and a first duct attached to the support (12) and in fluid communication with the first compartments. The assembly comprises a second compartment (125) arranged for conveying fluid and different from the first compartment, and a second duct attached to the support (12) and configured to be in fluid communication with the second compartment (125).

An easily assemblable water filtration device includes an inlet manifold for receiving a colloidal suspension including colloidal particles in water; and a diffusiophoretic water filter having at least one channel having an inlet and an outlet and for receiving the colloidal suspension at the inlet from the inlet manifold and flowing the colloidal suspension between the inlet and the outlet in a flow direction, the diffusiophoretic water filter having a pressurizable gas chamber for providing pressurized gas to the at least one channel via a gas permeable and water impermeable membrane. An outlet splitter connects to or is at the outlet, the outlet splitter having a first splitter outlet and a second splitter outlet, the first splitter outlet for receiving water having a higher concentration of some of the colloidal particles than a second splitter outlet. The outlet splitter, the membrane and at least parts of the inlet can be removable.
