Apparatus for purification of industrial wastewater with thin film fixed bed TiO2 photocatalyst

摘要

An apparatus for the photocatalyitc oxidation of common industrial effluent contaminants in aqueous solution includes a reactor and a thin film photocatalyst fixed to a support material like Cuddapah stone. The support material is preferably an inert material. The TiO2 preformed does not contain any adsorbent for making the thin film photocatalyst, The catalytic runs were carried out over TiO2 thin film fixed bed reactor. The study is extended to the immobilization of preformed TiO2 with a binder for making thin film using a simple spray technique on inert Cuddapah stone. This method of immobilization require no thermal treatment of the catalyst at high temperatures. The method is applicable for the photocatalytic treatment of industrial effluents at a higher scale. Also it is a method for preparing a photocatalyst adopted for the oxidation of industrial common effluent by simple spray technique. Also it is a method and apparatus for destroying industrial common effluent contaminants in aqueous solution
