| 20100133202 | WASTEWATER TREATMENT BY HIGH EFFICIENCY HETEROGENEOUS PHOTO-FENTON PROCESS - This invention presents the set-up of a heterogeneous photo-Fenton system for the abatement of organic pollutants in liquid wastewater by means of heterogeneous perovskite-based catalysts, both in powder and in structured form. The proposed method employs, preferably, structured honeycomb monoliths consisting of a perovskite-based material (unsupported catalyst), or structured honeycomb monoliths made of a refractory carrier or a foam impregnated with a solution of salts corresponding to the desired perovskite (supported catalyst). The removal of organic substances is carried out at room temperature and atmospheric pressure, through an oxidation to gaseous CO | 06-03-2010 |
