“…Although the adoption of UV for wastewater disinfection has grown significantly over the past few decades, research on the ability of the UV process to remove ARB&ARGs is only advancing during the recent years [13], [14]. To date, there is limited data available on the potential of light-driven processes to simultaneously remove antibiotics, ARB and ARGs from wastewater [15], [16], [17]. More systematic analysis of the operational parameters of the lightdriven processes and their impact on the overall efficiency of the technologies to remove such microcontaminants is required.…”

“…Therefore, considerable effort has been made in recent years to identify an optimal treatment method to remove antibiotics from wastewater. Thus, the possibility of removing the antibiotics through adsorption [5,6], advanced oxidation [7,8], and biological processes has been intensively studied [9][10][11]. Of all these methods, photocatalytic oxidation, and especially heterogeneous photocatalysis with TiO 2 , has received particular attention due to the advantages that this method offers [12].…”

New photocatalytic membranes based on polylactic acid (PLA)/TiO2 hybrid nanofibers deposited on fiberglass supports were prepared and tested for the removal of ampicillin from aqueous solutions. The electrospinning technique was used to obtain hybrid nanofibers that were deposited on three types of fiberglass with different structures, resulting in three distinct photocatalytic membranes namely fiberglass fabric plain woven-type membrane, fiberglass mat-type membrane, and fiberglass fabric one-fold edge-type membrane. The results of the photocatalytic tests showed that the highest efficiency of ampicillin removal from aqueous solution is obtained with the fiberglass fabric plain woven-type membrane. Although it has been shown that the rate of photocatalytic degradation of ampicillin is high, being practically eliminated within the first 30 min of photocatalysis, the degree of mineralization of the aqueous solution is low even after two hours of photocatalysis due to the degradation of PLA from the photocatalytic membrane. The instability of PLA in the reactive environment of the photocatalytic reactor, evidenced by morphological, mineralogical and spectroscopic analyzes as well as by kinetic studies, is closely related to the structure of the fiberglass membrane used as a support for PLA/TiO2 hybrid nanofibers.

“…These results confirm the advantage of solar/Fe/S 2 O 8 2− when compared to solar disinfection alone for the removal of ARB. Although some studies reveal that ARB relative abundance increases during solar photo-Fenton treatment, it may not be necessary to evaluate the ARB inactivation rate as a particular indicator, since it takes longer to remove pathogen indicators as the former are present in higher concentrations in real wastewater when compared to ARB (Fiorentino et al 2019). Also, solar/Fe/S 2 O 8 2− was similarly effective for total and resistant bacteria (Fig.…”

This work investigated an innovative alternative to improve municipal wastewater treatment plant effluent (MWWTP effluent) quality aiming at the removal of contaminants of emerging concern (caffeine, carbendazim, and losartan potassium), and antibiotic-resistant bacteria (ARB), as well as disinfection (E. coli). Persulfate was used as an alternative oxidant in the solar photo-Fenton process (solar/Fe/S2O82−) due to its greater stability in the presence of matrix components. The efficiency of solar/Fe/S2O82− at neutral pH using intermittent iron additions is unprecedented in the literature. At first, solar/Fe/S2O82− was performed in a solar simulator (30 W m−2) leading to more than 60% removal of CECs, and the intermittent iron addition strategy was proved effective. Then, solar/Fe/S2O82− and solar/Fe/H2O2 were compared in semi-pilot scale in a raceway pond reactor (RPR) and a cost analysis was performed. Solar/Fe/S2O82− showed higher efficiencies of removal of target CECs (55%), E. coli (3 log units), and ARB (3 to 4 log units) within 1.9 kJ L−1 of accumulated irradiation compared to solar/Fe/H2O2 (CECs, 49%; E. coli, 2 log units; ARB, 1 to 3 log units in 2.5 kJ L−1). None of the treatments generated acute toxicity upon Allivibrio fischeri. Lower total cost was obtained using S2O82− (0.6 € m−3) compared to H2O2 (1.2 € m−3). Therefore, the iron intermittent addition aligned to the use of persulfate is suitable for MWWTP effluent quality improvement at neutral pH.
