The present invention relates to a method for manufacturing a hollow fiber membrane module by using an open hollow fiber membrane cartridge, and a hollow fiber membrane module manufactured by same, the method for manufacturing a hollow fiber membrane module according to an embodiment of the present invention comprising the steps of: preparing a hollow fiber membrane cartridge; opening the hollow fiber membrane cartridge; arranging a hollow fiber membrane on the opened hollow fiber membrane cartridge; and closing the hollow fiber membrane cartridge on which the hollow fiber membrane is arranged.

The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid. In addition to a wind turbine generator and a wave energy generator, a photovoltaic array or a marine current generator may be utilized to power these applications. Alternatively, the desalination vessel operates with the assistance of shore-based power provided by cable.

The present disclosure relates to devices and processes for the production of hollow fiber membrane bundles. The bundles are used for the manufacture of filtration and/or diffusion devices, e.g., capillary dialyzers.

A reverse osmosis water production apparatus for use in a body of water includes a first section defining a buoyancy chamber and an elongate second section connected to the first section and configured to define an elongate chamber which extends downward beneath a waterline in use. The elongate chamber is provided with a plurality of elongate reverse osmosis membrane tubes, each tube containing a reverse osmosis membrane. A longitudinal axis of each reverse osmosis membrane tube is substantially parallel with a longitudinal axis of the elongate chamber and the reverse osmosis membrane tubes are arranged around a passage.

A high velocity cross flow dynamic membrane filtration system disc membrane assembly includes a frame having first and second end members and a plurality of rails extending between the first and second end members. At least two parallel support shafts are coupled to the frame, each support shaft defining a longitudinal axis about which is positioned a plurality of axially spaced membrane discs. The plurality of membrane discs associated with one of the at least two parallel support shafts is interspersed between the plurality of membrane discs associated with another of the at least two parallel support shafts. Each rail of the plurality of rails is configured to be received by a mounting rail within a vessel defining a treatment chamber. A permeate tube is coupled to each support shaft and in fluid communication with the membrane discs associated with that support shaft.

Provided is a membrane module which has a simple and easy structure to restrain its vessel from being increased in costs, and which allows to fabricate the vessel by a simple and easy work, and further to locate an inlet for a fluid, and others at respective predetermined positions of the membrane module.

A hollow fiber membrane module includes one pressure vessel, and at least one hollow fiber membrane element loaded in the pressure vessel. Each of the element includes a plurality of hollow fiber membranes each having openings at both ends, a bypass tube, and a supply port and a discharge port provided on one end side in a longitudinal direction. The supply port is in communication with inflow-side openings of hollow fiber membranes. The bypass tube is provided in the longitudinal direction of the element, has an inflow port at an end portion on a side of outflow-side openings of the hollow fiber membranes, and has an outflow port at an end portion on a side of the inflow-side openings of the hollow fiber membranes. The outflow-side openings of hollow fiber membranes are in communication with the inflow port, and the outflow port is in communication with the discharge port.

Provided are a plate-type filter module for water treatment and a filter assembly for water treatment comprising the same. The plate-type filter module for water treatment according to one embodiment of the present invention comprises: a plurality of filter units having a predetermined area and formed in a plate shape; a block frame to which the plurality of filter units is engaged so that the filter units are kept parallel to each other; and a collecting/receiving tube fixed on one side of the block frame and including a plurality of first fittings respectively connected to the plurality of the filter units to allow filtered water produced in the filter units to be introduced thereinto and at least one second fitting for discharging the filtered water introduced through the plurality of first fittings to the outside.

Filtration head (1) for a filter system, comprising base (2) including filter support (3) for removable filter element (4) and a fluid path from one side of filter element (4) on filter support (3), through filter element (4), and to drainage outlet (5) of base (2), and holder device (6) for removably attaching funnel (7) to base (2) to form a sample fluid reservoir on one side of filter element (4), wherein holder device (6) comprises ring-shaped element (8) configured to extend about bottom peripheral flange (7a) surrounding a lower end of funnel (7) and to selectively apply a biasing force on a radially outward protruding portion (7b) of bottom peripheral flange (7a) of funnel (7) to press funnel (7) against base (2). The filtration head allows the use of cardboard funnels without risk of liquid leakage between the funnel and the base.

An apparatus for calibrating a flux analyzer comprises a first frame; a second frame; and a permeable membrane. The first frame and the second frame are connected or integrally formed. A method for calibrating a flux analyzer is provided which uses an artificial standard rather than a biological standard.
