摘要： The present invention involves a system for treating contaminated gas comprising a gas scrubber (204), the contaminated das being transferred into the scrubber (204) in a manner so as to generate a contaminated gas stream, which is directed upwards through the gas scrubber (204); an injection device (206) on top of the scrubber (204), which disperses a solvent downwardly into the scrubber (204) by which the contaminants are transferred from a gaseous phase to a liquid phase; means (212, 216) for transferring liquid solvent containing the contaminants from the bottom of the gas scrubber (204) to a photocatalytic system (218) which is operable to reduce contaminants into non-harmful materials; means for recirculating the solvent from the photocatalytic system (218) to the injection device (206) in a closed loop.

摘要： A method and system for purifying a contaminated fluid in a continuous manner is herein disclosed. The present invention provides for the irradiation of a slurry between a defined surface(s) such that substantially all of the contaminants are removed from the slurry, and a turbulent flow of the slurry is achieved. The present invention further provides for the separation of decontaminated effluent from the slurry by employing ceramic membrane filters. Air is applied to the ceramic membrane filters at relatively high pressures in order to remove any photoreactive catalyst particles that have collected in the ceramic membranes.

摘要： A system for treating contaminated media including air, soil or adsorbents is provided. In the process, contaminants are removed from the media using a photocatalytic process operating in an aqueous phase. The system comprises a converter such as gas scrubber (204) or adsorbent system to transfer contaminants from the contaminated media into a solvent such as water stream and a photocatalytic system (218) comprising photocatalyst slurry coupled to the converter.
