Abstract

This paper deals with the problem of the photocatalytic reactor construction. The supported TiO₂ on γ- Al₂O₃ modified with Mo or V addition was used as the photocatalyst, whereas phenol and formaldehyde were chosen as the model pollutants. The counter - current contact of reagents and catalysts is the main advantage of the construction and enables a significant COD reduction of the highly concentrated wastewaters.
