[en] Benzotriazole, carbamazepine, clarithromycin and diclofenac have been identified as microcontaminants of concern in Luxembourgish wastewaters, thus the implementation of photo-Fenton processes at natural pH has been proposed for their removal. In the present work, the effectiveness of a pilot scale photo-Fenton system (500W Medium Pressure) has been evaluated according to the reagent dosage and toxicity of the treated effluent. With this treatment, 80% degradation is achieved in 15 minutes even with 5 and 3 mg/L of iron (40 mg/L H2O2), but 5 mg/L can have a negative effect on the growth of Sorghum saccharatum in Phytotoxicity tests. In comparison UV-C/H2O2 (40W Low Pressure; 40 mg/L H2O2) process needs longer treatment time and generates degradation by-products causing a growth inhibition of Sorghum saccharatum. The combination of both lamps can lead to a better performance of the reagents allowing to reach the 80% target in less time and to reduce the dosage. | |
