Photocatalytic Reactor:

Photo catalytic degradation is the degradation of photodegradable molecules by absorption of photons, particularly those wavelengths found in sunlight such as infrared radiation, visible light and ultraviolet light in presence of catalyst. Removal and degradation of organic dyes are matter of considerable interest, because of potential toxicity of dyes and theirs visibility in surface waters. A wide range of methods have been developed, amongst which the heterogeneous photo catalysis involving titanium dioxide (TiO2) appears to be the most promising technology. Here we express the designing of photo catalytic reactor, with or without aeration system in batch mode, for observing catalytic degradation performance of Methylene Blue (MB) removal. Dye removal kinetics, effect of aeration, initial dye concentration, catalyst dose on batch mode was investigates in this paper. A comparison of photo catalytic degradation between aeration and without aeration on batch mode also performed. It is found that, with aeration the dye degradation is much better than without aeration.
