Abstract: The invention relates to a device (1) through which particles can pass, for separating substances by means of the permeation of liquids of more than one layer of porous, flat adsorption membranes (5). The device is characterized by a high adsorption capacity, even penetration of the target substance and a simple structure. The layers of adsorption membranes (5) are set apart from each other and are provided with at least one hole (6), preferably a number of holes (6), to allow the passage of particles (8). The inventive devices can be used to treat liquids containing particles, as are found e.g., in biotechnology, in the pharmaceutical, food and chemical industries or in the area of water and sewage.

Abstract: The invention relates to a device for dehydrating and/or degassing hydraulic fluids, a device for carrying out said method and the use of said device. Air entering a hydraulic system impairs the function of the system and causes wear and tear by cavitation, especially if the system is driven hydrodynamically. Various types of hydraulic fluid are hygroscopic, which results in absorption of water and, if the temperature of the hydraulic fluid is raised substantially, as is often the case in hydraulic systems, in the subsequent formation of steam. The latter in turn impairs the functioning of the system and causes wear and tear. The invention provides for a method by which gases dissolved and/or water contained in the hydraulic fluid are separated from the hydraulic fluid according to the principle of pervaporation using a membrane (9) permeable to the gas and/or water and impermeable to the hydraulic fluid, whereby in the area of said membrane a partial pressure differential for gases and/or water is maintained.

Abstract: A process and apparatus for treating the heavy hydrogen isotope content of the contaminated water by contacting the contamined water with a molecular separation material (28) including a support medium carrying a plurality of hydration sites having associated waters of hydration, whereby a portion of the waters of hydration are replaced with heavy hydrogen isotope water molecules from the contaminated water. The hydrogen isotope water molecule content of the contaminated water is thus decreased. The molecular separation material (28) is preferably a polymer, such as a polystyrene/divinyl benzene cross-linked polymer, having hydration sites with associated waters of hydration. Preferred hydration sites are obtained by reacting the polymer which has been sulfonated or phosphonated to create reactive sites, with a salt of, for example, aluminum, sodium, magnesium, copper, zinc, cobalt, iron, nickel, manganese, potassium and chromium. Before or during contact with the molecular separation material (28), the contaminated water may be brought into contact with a separation membrane (12) selectively permeable to light water molecules relative to hydrogen isotope water molecules, to remove light water molecules from the water, thereby increasing the concentration of said hydrogen isotope molecules.

Abstract: The present invention is a microchannel mass exchanger (100) having a first plurality of inner thin sheets (106, 116, 200, 300) and a second plurality of outer thin sheets (110, 118, 204, 302, 504, 510). The inner thin sheets (106, 118, 200, 300) each have a solid margin (108) around a circumference, the solid margin (108) defining a slot (104, 508) through the inner thin sheet (106, 116, 200, 300) thickness. The outer thin sheets (110, 118, 204, 302, 504, 510) each have at least two header holes (112, 202) on opposite ends and when sandwiching an inner thin sheet (106, 116, 200, 300). The outer thin sheets (110, 118, 204, 302, 504, 510) further have a mass exchange medium (400, 500). The assembly forms a closed flow channel assembly wherein fluid enters through one of the header holes into the slot and exits through another of the header holes after contacting the mass exchange medium.
