An extracorporeal blood treatment machine for carrying out a blood treatment including a machine front on which a hollow fiber filter module is arranged in a horizontal position, which hollow fiber filter module includes a cylindrical housing, a blood chamber having a blood inlet nozzle and a blood outlet nozzle and a solution chamber having a solution inlet nozzle extending transversely to the longitudinal direction of the hollow fiber filter module and a solution outlet nozzle extending transversely to the longitudinal direction of the hollow fiber filter module, the solution chamber being semi-permeably communicated at least in portions with the blood chamber, wherein a height potential is present in the horizontal position between the solution inlet nozzle and the solution outlet nozzle so that drainage of solution is enabled via one of the solution nozzles and evacuation of air bubbles is enabled via an other of the solution nozzles.

An apparatus utilizes a membrane unit to capture components from atmospheric air, including carbon dioxide, enriches the carbon dioxide concentration, and delivers the enriched concentration of carbon dioxide to a sequestering facility. The membrane is configured such that as a first gas containing oxygen, nitrogen and carbon dioxide is drawn through the membrane, a permeate stream is formed where the permeate stream has an oxygen concentration and a carbon dioxide concentration higher than in the first gas and a nitrogen concentration lower than in the first gas. A permeate conduit, having a vacuum applied to it by a vacuum generating device receives the permeate stream and a delivery conduit delivers at least a portion of the enriched carbon dioxide to a sequestering facility. The apparatus may comprise a component of a system where the system may have a flue gas generator and/or a secondary enrichment system disposed between the vacuum generating device and the sequestering facility.

A submerged offshore reverse osmosis desalination apparatus and method uses desalinated product water from the apparatus and an onshore cooler or heat exchanger to provide or improve the cooling of an onshore Rankine Cycle heat engine.

The invention concerns a filtration assembly (1) for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a drain member (30) removably and fluid tightly attachable to the membrane support (10) to define a drain channel space adjacent to the filtration membrane (11) on an opposite axial side of the membrane support (10).

The present invention relates to novel cartridges and modules for separation of fluid mixtures, especially for gas separation, to a process for production thereof and to a method of use thereof.
