Magnetic Photocatalyst for Wastewater Tertiary Treatment at Pilot Plant Scale: Disinfection and Enrofloxacin Abatement

Abstract: In this work, we have tested a photocatalytic material consisting of a core of SiO2/Fe3O4 coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, a pilot plant of 45 L equipped with an Ultraviolet light (UVC) lamp was employed to study the degradation of a model contaminant, enrofloxacin (ENR), as well as water disinfection (elimination of Escherichia coli and Clostridium perfringens). The influence of different operational conditions was explored by means of dye (rhodamine-B) decolori… Show more

“…233 The design of such systems have been proposed, 234 and have very recently been applied at scale. 235 These early tests have again confirmed the efficacy of MNPCs, and show that with a small boost in efficiency they would be as effective as traditional toxic techniques utilising H 2 O 2 .…”

“…One of the main objectives addressed by more recent studies is to extend the use of TiO 2 -based photocatalysts to solar (visible) light for the application in areas without electricity or as a sustainable solution to avoid the use of bio-hazardous and costly UV light [13][14][15][16]. To respond to this very urgent and necessary need, different pollutant treatments with visible light-responsive photocatalysts have been developed, which are mainly based on TiO 2 modification [17]; nevertheless, the majority of works are carried out on a laboratory scale, and the introduction of other materials into TiO 2 dramatically increases the complexity of the photocatalyst preparation and cost, and the modification with heavy metals or harmful organics could even improve the degree of environment pollution [18,19].…”

“…This section shows the information from the publication referenced as [187] rhodamine-B (RB) has been employed to characterize the system under the different operating conditions; this dye was chosen because it is commonly employed and easy to monitor spectrophotometrically [188][189][190]. Then, the degradation of ENR was studied under selected conditions.…”
