The novel rectangular continuous photoreactor equipped in ultraviolet (UV) light is studied for the degradation of Acid Red 14 as a model of organic pollutant in water. TiO2 photocatalysts have been immobilized on the tile by white cement. The tile has been applied as a support for photocatalyst, because can be easily removed and replaced in a reactor, what facilitates the performance of the photocatalytic process. Removal efficiency of Acid red 14 depend on operational parameters such as TiO2 content (TiO2/cement, w/w ratio), pH, initial concentration of dye. Neutral pH and room temperature found to be optimum conditions
