A method of desalinating water through application of acoustic pressure shock waves to a slush to separate ice crystals from brine and recovering desalinated water from the separated ice crystals.

A hollow fiber membrane module includes a housing having an inlet formed one end thereof and an outlet formed on the other end thereof, in which hot and humid humidifying fluid flows in through the inlet and the humidifying fluid after humidifying a cool and dry fluid flowing out of the housing through the outlet; at least one hollow fiber membrane bundle which is inserted into the housing in the longitudinal direction; a partitioning part for supporting the hollow fiber membrane bundle and partitioning an inflow space, in which the humidifying fluid flowing into the housing momentarily remains, and an outflow space, in which the humidifying fluid momentarily remains before being discharged through the outlet; and a potting part for potting both ends of the hollow fiber membrane bundle to the housing.

The invention relates to a hollow fiber membrane filter for purifying liquids with improved separation properties, comprising a cylindrical housing, first inflow or outflow spaces and second inflow or outflow spaces, each of which surrounds a first and a second end region of the cylindrical housing, the cylindrical housing being embodied in at least one end region such that improved flow of a liquid against the hollow fiber membranes in the interior of the cylindrical housing can take place.

The present invention relates to portable filtration units including filter components mated with retentate and permeate flow channels wherein particle containing solutions are introduced into the portable filtration units and contacted with the filter components for filtration thereby producing a retentate outflow and a permeate outflow for capture of desired end product.

The present invention is directed toward a dialysis unit that is modular and portable, with improved functionality. In one embodiment, the dialysis system comprises a top unit that is detachably affixed to a base that comprises a reservoir for fluid storage. Among numerous other features, the portable, modular dialysis system of the present invention has improved power door locking, zoned leak detection, fluid handling, and mechanical design features that enable improved modularity.

A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib associated with the membrane that decreases the gap between the membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously collected whole blood into components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.

A desalination apparatus and a method of desalinating thereof, wherein the desalination apparatus comprises a perforated vessel and at least one engineered semi-permeable membrane that covers perforations on the perforated vessel, wherein the desalination apparatus forms a purified water from saline water when submerged in the saline water to a depth of 50-250 m to create sufficient pressure differential on both sides of the engineered semi-permeable membrane, wherein low-saline water flows through the engineered semi-permeable membrane and collected within an internal cavity of the desalination apparatus. Various embodiments of the desalination apparatus and the method of desalinating are also provided.

A water storage tank built for a reverse osmosis water purifying system deploys multi water flow passages of purified water and drainage water, allocated a soft bladder unit receiving purified water encompassed by the waste water in the tank. When the water tank unit is fully filled with water, the water pressure activates the auto-shut-off valve or solenoid valve to stop operation of the reverse osmosis water purifying system. When the dispensing faucet is turned on, the drainage water swells to squeeze the soft bladder unit to deliver the purified water out from the soft bladder unit to the dispensing faucet, and the drainage water flushes the reverse osmosis membrane as well. The technique enables the tank to take the least water pressure resistance to hold water and drain water which results in energy saving and water saving.

A hollow-fiber membrane module according to an embodiment of the present disclosure includes a rectangular tubular outer casing with at least one sidewall being open, the outer casing having a plurality of open ports, and an inner casing configured such that a plurality of hollow-fiber membranes aligned in a longitudinal direction of the outer casing are placeable in the inner casing and configured to be insertable into the one sidewall.
