| Popis: | For the first time, two strategies of solar photo-Fenton at neutral pH (with FeSO4 and Fe3+-EDDS) are techno-economically assessed. With the target of simultaneous wastewater disinfection and removal of contaminants of emerging concern (CECs), a cost estimation ranging from 0.13 to 0.49 €/m3 as a function of the treatment goal is presented. To this end, the effects of liquid depth (5, 10 and 15 cm) and the iron species were studied at lab-scale. Afterwards, the feasibility of both operating strategies was evaluated and validated outdoors at pilot plant scale in low-cost raceway pond reactors. For the joint-removal of bacteria and CECs, the use of FeSO4 as iron source was cheaper than Fe3+-EDDS. However, it is important to highlight that although bacterial inactivation reached > 3 log, only around 35 % of CEC degradation was achieved with FeSO4, while more than 80 % CEC load was removed with Fe3+-EDDS. |
