Abstract:
The invention describes a device (1) for at least partially separating a solvent from a solution (6), comprising at least one membrane filter unit (2) which has a solution feed element (8), a solvent outflow and a concentrate outlet (5) for a concentrate produced from the solution (6). Upstream of the solution feed element (8), at least one unit (7) is arranged on the membrane filter device (2) for generating a rotating or swirling flow in the solution (6). Optionally, magnets (24), a laser (25) and/or a gas suction device (26) are arranged on the device (7). Said device (7) can be operated in the bypass flow.
Abstract:
Apparatus and methods are disclosed for using an ultraviolet laser system to decompose selected chemical substances in water. More particularly, this invention provides methods and apparatus whereby various environmental pollutants in water are rapidly decomposed to very low concentrations, consistent with environmental discharge regulations, use requirements, and/or applicable health standards, by means of exposure to ultraviolet laser irradiation (10, 20), either with or without one or more catalysts and/or other chemical additives to facilitate or enhance the decomposition process.
Abstract:
A system (100, 200, 300) and method for the on-demand on-line treatment of water is disclosed. The system (100, 200, 300) uses ultra high energy UV light coupled with the introduction of a strong oxidant to induce photo-catalytic degradation of chemical compounds and biocidal activity. When an agent or substance is detected in the water the treatment system (100, 200, 300) would be activated.
Abstract:
An apparatus and method are disclosed for removal of material from a substrate or structure using a broadband flashlamp-type radiator (200) for providing broadband radiant energy (204), an ultraviolet radiator (302), lamp head or other focusing means (212) for directing the broadband radiant energy (204) and ultraviolet radiant energy (306) onto the surface of the coating or coatings or other material to be removed, thereby resulting in the ablation and photodissociation of the material, and a residual constituents removing means (108), such as flowing CO2 pellets, liquid CO2, jets of compressed air, particles or other flowing gases or liquids.
Abstract:
A liquid treatment apparatus configured for ultraviolet light treatment of a liquid (4) in a liquid container (6), the apparatus comprises an ultraviolet light source (8) configured to emit ultraviolet (UV) light (10) having one or many wavelengths within a predetermined wavelength range to treat said liquid. The apparatus comprises a translucent wall (12) provided with a surface facing the liquid to be treated. Its surface is covered with a pure synthetic diamond layer (14) configured to be in contact with the liquid to be treated and through which combined translucent wall (12) and pure synthetic diamond layer (14) one or many wavelengths of said UV-light is to be transmitted. Thereby the formation of scaling/fouling at the surface in contact with the liquid is essentially eliminated. In one embodiment the pure synthetic diamond layer is applied by using a chemical vapour deposition (CVD) technique.
