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.

摘要: A device for dispensing liquids in a desired ratio comprises conduits (52-57) extending from containers (50, 51) of the liquids to a mixing chamber (60) wherein the liquids are mixed and from which the mixture is dispensed. Located in each of the conduits is a valve means (60, 61), and the dispenser comprises flow sensing means (27, 33) comprising a flow meter for each liquid which is operative to produce an output signal proportional to the quantity of liquid flowing through the conduit. The flow sensing means comprises a flow control member (27) rotatable by flow of liquid through the conduit at a rate proportional to the rate of flow of liquid, and detection means (12, 13) is provided which is operative to detect the rate of rotation of the flow member. In this way the relative proportions of the two liquids flowing into the mixing chamber (60) may be measured, so that the appropriate valve means may be operated to terminate flow of that liquid which is in excess.

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: 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.
