Devices and techniques may improve the permeate productivity in membrane distillation separation by modifying the feed and/or coolant sides of a membrane distillation module depending on the membrane distillation configuration. The bubbling of a carrier gas through the feed liquid in the feed liquid side of the module can increase the turbulent dissipation rate and/or enhance mass transfer across the membrane pores.

A priming subsystem of a cell processing system carries out a method for priming a spinning membrane separator having an inlet and first and second outlets. The method includes opening a first selectable junction disposed between a priming fluid container and the inlet to open a path between the priming fluid container and the inlet, operating a first pump coupled to the first outlet to draw priming fluid from the priming fluid container into the spinning membrane separator, and closing the first selectable junction and a second selectable junction coupled to the second outlet after drawing the priming fluid into the spinning membrane separator. The method further includes operating the first pump after the first selectable junction is closed to draw a vacuum, and opening the first selectable junction after drawing the vacuum.

A gas separation module includes hollow polymeric fibers held between a pair of tubesheets. The tubesheets are mounted to a core tube, and the distance between the tubesheets is maintained constant. The core tube is formed in telescoping sections, such that the fibers are attached to the tubesheets when the core tube is in its extended position, and the core tube is then collapsed, forming slack in the fibers. The core tube includes two distinct channels, connected to receive permeate and retentate gas streams, and to carry these streams to outlet ports while keeping the streams separate. Because the tubesheets are affixed to the core tube, the tubesheets do not move under the influence of gas pressure in the module. The slack in the fibers compensates for shrinkage of the fibers, prolonging the life of the module.

A membrane filter apparatus for splitting a feed into filtrate and retentate is provided. The apparatus comprises a body chamber, a feed inlet disposed on the body chamber, a retentate outlet located in the body chamber, a feed distribution tube connected to the feed inlet, and a filter assembly having a filter. The feed distribution tube has a length sufficient to cause the feed to enter the body chamber at a feed distance from the filter assembly of no greater than 50% of a total length of the body chamber. The feed flows across the filter in a direction parallel to a surface of the filter assembly. The filtrate passes through the filter assembly and the retentate flows through the body chamber in a direction antiparallel to the feed flow through the feed distribution tube and out through the retentate outlet.

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.

A membrane filter configured to filter a liquid, the membrane filter including a base element including at least one membrane carrier that is externally flowable by the liquid and a gas; hollow fiber membranes respectively including lumen and attached at a top of the at least one membrane carrier wherein a liquid permeate is filterable from the liquid into the lumen; a one piece extruded circumferentially closed pipe that envelops the hollow fiber membranes; a gas inlet configured to let gas into a bottom of the membrane filter; at least one permeate collection cavity included in the base element and connected with the lumen and configured to collect the liquid permeate from the hollow fiber membranes; a permeate outlet included in the base element and configured to drain the liquid permeate from the at least one permeate collection cavity laterally from the base element.

A separation device includes a membrane separation module (10), an adsorption module (20), and a gas intake module (30). The membrane separation module includes a first housing (110), and a membrane assembly (130) disposed in the first housing. The first housing has a first gas inlet (121), a first gas outlet (122), and a retentate gas outlet (123). The membrane module has a permeate gas outlet, the permeate gas outlet being in communication with the first gas outlet. The adsorption module has a second housing (210) and an adsorbent layer (230) disposed in it. The second housing is disposed on the first housing and has a second gas inlet (221), a second gas outlet (222), and a desorption gas outlet (223). The second gas inlet is in communication with the first gas outlet. The gas intake module has a third gas outlet (321) in communication with the first gas inlet.

An artificial lung device includes: a housing which is formed in a tubular shape including both end portions closed, includes a blood inflow port and a blood outflow port, and is arranged such that a center axis of the housing is directed in a lateral direction; a hollow fiber body (gas exchanger) which is arranged in the housing and performs gas exchange with respect to blood while the blood flows from the blood inflow port to the blood outflow port; and a straightening frame (gas guide portion) by which a gas having flowed through the gas exchanger by the flow of the blood is guided to the gas exchanger again in the housing.

A degasification system includes a plurality of degasification units which degasifies a liquid and a cylindrical housing which houses the plurality of degasification units in parallel. Each of the plurality of degasification units includes a hollow fiber membrane bundle in which a plurality of hollow fiber membranes are bundled in a cylindrical shape and a cylinder in which the hollow fiber membrane bundle is housed. The housing has an inlet, an outlet, and a sealing portion which partitions an internal space of the housing into an upstream side region on the inlet side and a downstream side region on the outlet side via the plurality of degasification units. The plurality of degasification units are configured such that pressure losses of the liquid differ depending on a distance from a central axis of the housing.
