Removal of 14 different micropollutants corresponding to representative families of drugs and hormones was evaluated during solar disinfection of water using Escherichia coli as indicator microorganism. Laboratory experiments using a small scale photoreactor coupled to a compound parabolic collector operated under xenon lamp solar simulated light were carried out. Different values of radiation flux, concentration of pollutants, catalyst loading and irradiated-to-dark volume ratio were used. A rigorous kinetic modeling approach based on the reaction mechanism and the explicit consideration of radiation absorption step was able to reproduce the experimental data. Validation of model predictions was carried out using experimental data of the reactor operation under real sun conditions.
