In one embodiment, a renewable energy storage system includes a forward osmosis system, a hydro-turbine, and a separation (e.g., CEDI) system powered by one or more natural regenerating energy sources, such as wind or solar. In another embodiment, a renewable energy storage system includes a forward osmosis system, a hydro-turbine, a solar thermal heat exchanger through which the diluted osmotic draw solution can be directed for purposes of heating up the draw solution, and a solvent-water separator configured to separate the draw solution from the water. One example method includes drawing water across a forward osmosis membrane in a forward osmosis system such that the water drawn across the membrane dilutes an osmotic draw solution; directing the diluted osmotic draw solution to drive a hydro-turbine to produce energy; and separating the water from the draw solution using one or more natural regenerating energy sources.

An Oxygenator as a medical instrument includes at least one first hollow fiber membrane layer comprised of a plurality of integrated first hollow fiber membranes, and forms a shape of a cylindrical body as a whole, and at least one second hollow fiber membrane layer disposed at the outer circumferential side of the first hollow fiber membrane layer in a state of being concentric with the first hollow fiber membrane layer, has a plurality of integrated second hollow fiber membranes, and forms a shape of a cylindrical body as a whole. Moreover, each of the first hollow fiber membranes is wound around a central axis, and each of the second hollow fiber membranes is wound around a central axis. The number of times the second hollow fiber membranes are wound is smaller than the number of times the first hollow fiber membranes are wound.

A one-way valve includes a housing with a center axis. The housing includes a peripheral side wall around the center axis, and an inward flange protruding from the peripheral side wall toward the center axis. A valve member is inserted into the housing and includes an outer peripheral surface around the center axis, and an outward flange protruding from the outer peripheral surface toward the peripheral side wall. A coil spring includes a first axial end having a first diameter and being in contact with the inward flange and the peripheral side wall, a second axial end having a second diameter smaller than a first diameter, the second axial end being in contact with the outward flange and the outer peripheral surface, and a body portion provided between the first axial end and the second axial end and having diameters decreasing from the first diameter to the second diameter.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.

A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.

A distillation system includes a first liquid inlet, a first liquid outlet, and a first membrane coupled to the first liquid inlet and the first liquid outlet, the first membrane being impermeable to a first liquid mixture and permeable to a gas. The distillation system further includes a first gas inlet and a first gas outlet fluidically coupled to the first gas inlet via the first membrane.

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.
摘要:
Within the scope of hydrothermal carbonization of biomass, not only the main product, coal, but also the platform chemical 5-hydroxymethyl furfural, as well as furfural and levulinic acid, are formed. These are extracted from the process water of the carbonization reaction. However, in this connection, the problem exists that humic substances deposit on the container walls of the extraction column and can only be removed again by means of great cleaning effort. Furthermore, oligomers clearly worsen the purity of the product. This problem is solved by a filtration cascade through which the process water passes before extraction. In this connection, first the impurities mentioned are removed in a first filtration stage, and the remaining products and educts are separated from one another in a second filtration stage. Only the products are passed to extraction.

A main object is to provide a method, a membrane module and a purified water manufacturing device that demonstrate a performance of manufacturing water stably for a long period of time and lower a salt concentration in purified water. In the method, raw water is made to flow along one surface of a gas-permeable membrane, vapor permeated through the gas-permeable membrane is condensed, and the purified water is obtained.
