1. Photo-Catalysis: Oxidation Process description Photo-Catalysis consists in degrading organic contaminants on TiO2 coated surface activated with photons produced by short UV waves (UV-C) at room temperature. Once activated, the TiO2 coated surface contains electron-hole-pairs. Once an oxygen and a carbon containing molecule adsorb on such an electron-hole-pair, they become chemi-adsorbed on the surface and activated. In such an unstable state, the 2 activated and side-by-side molecules can only react with each other and water and CO2 molecules desorb from the surface.
2. Photo-Catalysis: Process description
The combination of the photo-oxidation and photo-catalysis processes allows the system to be very compact. Consequently, this system has been called “Phoenix Compact”.
As for the photo-oxidation process, a catalyst module, situated after the photo-catalysis module, helps to complete the oxidation process and to convert the un-reacted ozone and oxygen radicals in O2.
