TiO2 nanoparticles were immobilized on a concrete surface of fixed-bed reactor and used for furfural photocatalytic degradation of real and synthetic wastewater. At optimum conditions of initial pH 9, TiO2 loading density 50 g/m2 and UV irradiation intensity 24 W, the furfural and COD removal were 98.3% and 84.2% respectively for synthetic wastewater after 5 h, while for real wastewater, COD and TOC removal reached 59.53% and 86.65%, respectively after 8 h. The composite reused for four consecutive cycles with maximum 4.4% reduction in efficiency for both cases. Moreover, pseudo-first-order kinetics were best fitted to experimental data in both cases.

Contaminated soil via crude oil was remediated through advanced oxidative process. A combination ofultraviolet and ultrasonic irradiation enhanced by Fenton reagents was presented as a promising methodwith high efficiency for this purpose. The total petroleum hydrocarbon (TPH) removing was designatedby central composite design (CCD) to operate at room temperature for 15 g/kg contaminant. The initialcontaminant concentration, hydrogen peroxide concentration, reaction time andfinally nano zero valentiron (NZVI) dosage were optimized to obtain high removal efficiency. It was found that sono-photo-Fenton oxidation has the highest removal efficiency among other methods.
