Experimental conditions of pilot plant
Liquid phase: 24 m3·d-1 Initial concentration of cianide: Ci = 10 ppm Final concentration of cianide: Cf = 0.2 ppm Reaction volume: 2.4 m3 Total volume: ca. 6 m3
Used catalyst: TiO2 (anatase) supported on Al2O3 (particle size: 90 – 110 μm).
Irradiating system consisted of 16 cilinder Pyrex tubes (lenght ca. 2 m). Every tube contain 8 fluorescent lamps of 40 W (height 60 cm).
Electric power needed to mantein a turbulent regime into the reactor was 12 KW.
