Abstract: An air treatment system (1) arranged for treating polluted air (Apol) at least by means of an air particle filter, and wherein said air treatment system comprises an air treatment unit placed upstream of the air particle filter and being arranged for directing a sub-flow (Asub) of the polluted air (Apol) through said air treatment unit (2) and for subjecting the sub-flow (Asub) to a photooxidation process. The photooxidation process in the air treatment unit (2) is so efficient that the overall concentration of gas-pollution of the combined air flow Acorn is significantly reduced whereby large volumes of polluted air can be treated in a fast, inexpensive and effective manner.

Abstract: The present invention relates to an air treatment system (1) comprising a sterilization unit (2) arranged for producing ozone, a photooxidation unit (3) arranged for subjecting an air flow to a photooxidation process, and a control unit (4) arranged for in a first operational mode directing an air flow through the sterilization unit (2), and in a second operational mode directing an air flow through the photooxidation unit (3). By providing an air treatment system (1) which can operate in two different modes i.e. in a photooxidation or a sterilization mode, it is possible to specifically remove the undesirable pollutants in the air, e.g.

Abstract: The present invention relates to an air treatment method and a system (1a-1f) arranged for treating an air flow (3) to be entered into a semiconductor clean room. Said air flow (3) comprises at least one vapour phase compound, and wherein the air flow (3) is subjected to at least one first treatment process arranged for reducing the concentration of the at least one vapour phase compound in the treated air flow below a predefined threshold, and wherein said first treatment process comprises subjecting the air flow to at least one photooxidation step.

Abstract: The present invention relates to a method and a system for the treatment of exhaust gas from industrial processes comprising at least the following consecutive steps: a) passing an exhaust gas comprising volatile organic compounds (VOCs) and/or amines through a catalytic zone at elevated temperatures, said catalytic zone comprises a deNOx-catalyst and an oxidation catalyst thereby providing a first treated gas stream, and b) subjecting the first treated gas stream to ultraviolet radiation in order cause photooxidation.

Abstract: An air treatment system comprising a plurality of excimer lamps, said system is arranged such that at least 90% of air flowing through the air treatment system will be exposed, to photons emitted from the excimer lamps, whereby the excimer lamps provides a large emission area in which high energy ultraviolet (UV) photons is provided at low cost. The photons will upon contact with contaminants in the air break down said contaminants through the process of photolysis, which is highly effective at removing different organic compounds, e.g. odours from the air. The system can be designed with different wavelengths, making the system a simple and inexpensive air treatment system both for use in large area industrial applications and for domestic uses.
