In a method for manufacturing an oxygenator, an intermediate spacer is disposed between a cylindrical heat exchange unit configured by winding a first hollow fiber membrane and a cylindrical gas exchange unit configured by winding a second hollow fiber membrane so that a first gap is formed between one end portions of the heat exchange unit and the gas exchange unit, and a first partition section of a first cover member is inserted into the first gap. In such an oxygenator, a first end portion of the intermediate spacer is located at a part that does not overlap the first partition section in a radial direction in the heat exchange unit and the gas exchange unit. The intermediate spacer is formed by winding an intermediate hollow fiber membrane.

A system for generating potable water from source water contains an enclosed vessel, a heating unit, an air distributor, a condenser, and a collection vessel. A method for generating potable water from source water includes heating ambient air, bubbling heated air through source water producing saturated air, cooling the saturated air producing potable water, and collecting the potable water. A method of removing contaminants from ambient air includes heating ambient air, bubbling the heated air through source water to produce treated air and contaminant rich water, discharging the treated air, and discharging the contaminant rich water.

A system may include an output manifold that may be in fluid communication with a reservoir and that may include multiple discharge ports. Each of the discharge ports may be configured to discharge electrorheological fluid into a housing. A recovery manifold may be in fluid communication with the reservoir and include multiple recovery ports. Each of the recovery ports may be configured to receive the electrorheological fluid from a housing. A gas remover may be positioned to extract gas from the electrorheological fluid received from the recovery ports. A housing may be connected to the system, and electrorheological fluid from the system may be pumped through the housing and the gas remover.

Embodiments provide a filter with a generally rectangular, non-cylindrical profile. The filter may have multiple pleat packs positioned between pleat covers that define regions and flow channels in a cavity of the filter body. The pleat covers have openings that allow a fluid to flow through the multiple pleat packs via parallel flows or series flows. End caps bonded to the body define flow passages for directing the fluid from an inlet to an outlet via the pleat packs for series or parallel filtration. The pleat packs may be made of the same or different materials and may be configured with the same or different heights based on flow requirements. A cage or a separator may be positioned between the pleat packs. The pleat packs may be made of a continuous pleated membrane with bridges defining a space between the pleat packs to accommodate the cage or separator.

This disclosure provides an integrated system and method for producing purified water, hydrogen, and oxygen from contaminated water. The contaminated water may be derived from regolith-based resources on the moon, Mars, near-Earth asteroids, or other destination in outer space. The integrated system and method utilize a cold trap to receive the contaminated water in a vapor phase and selectively freeze out water from one or more volatiles. A heat source increases temperature in the cold trap to vaporize the frozen contaminated water to produce a gas stream of water vapor and volatiles. A chemical scrubber may remove one or more volatiles. The integrated system and method utilize ionomer membrane technology to separate the water vapor from remaining volatiles. The water vapor is delivered for crew use or delivered to an electrolyzer to produce hydrogen and oxygen.

The present invention provides a preform coating device (5) provided with: a rotating and holding part (9) that holds a preform (1) in a horizontal direction, and rotates the preform (1) about an axis (A) of the preform (1); and a dispenser (6) that has a slot (62) and discharges a coating liquid in a plane form from the slot (62) to the preform (1), wherein the discharge direction of the coating liquid is the direction of the normal to an outer peripheral surface of the preform (1).

A degasification system includes a degasification unit in which a plurality of degasification modules degasifying a liquid are connected, wherein the degasification unit has a connection supply pipe which connects the liquid supply paths of the plurality of degasification modules in series and in which openings through which the liquid passes are formed at positions corresponding to the plurality of degasification modules such that the liquid is supplied to the hollow fiber membrane bundles of the plurality of degasification modules in parallel, and wherein the degasification unit is configured such that a pressure loss of the liquid from a supply port of the connection supply pipe through which the liquid is supplied to the discharge ports of a downstream side degasification module is larger than a pressure loss of the liquid from the supply port to the discharge ports of an upstream side degasification module.

A filtering device and a filtering method are provided. The filtering device includes a bubble filtering system. The bubble filtering system at least includes a first bubble filtering system and a second bubble filtering system. The first bubble filtering system configured for performing a first bubble filtration in the solution. The second bubble filtering system configured for performing a second bubble filtration in the solution. Filter fineness of the second bubble filtering system is higher than filter fineness of the first bubble filtering system.

A separation assembly comprises a housing and a bearing plate assembly. The housing contains a turbine assembly and a rotor portion and defines a fluid inlet and a fluid outlet. The bearing plate assembly is adjustably attachable to the housing and defines a drive jet that directs fluid from the fluid inlet to the turbine assembly. The bearing plate assembly is mountable to the housing in multiple different orientations such that the relative position of the fluid inlet of the housing and the drive jet of the bearing plate assembly is adjustable.
