Valorization of olive stone by-product as Fenton-like catalysts for olive mill wastewater treatment

(Corresponding) Esteves B., Morales-Torres S., Maldonado-Hódar F., Madeira L.
Topic: 
Advanced oxidation processes
The olive oil industry is responsible for the generation of highly-loaded and complex effluents (olive mill wastewaters, OMW) that pose several environmental threats. In particular, OMW’s polyphenolic fraction is known for its recalcitrant behavior and phytotoxic properties (McNamara et al., 2008...Read more

Solar photocatalytic degradation of pharmaceutical compounds using ZnSnO3/CB composites

Kouvelis k., Petala A., (Corresponding) Frontistis Z., Kondarides D.
Topic: 
Advanced oxidation processes
In this study, the activity of ZnSnO3 as a photocatalyst for the degradation of persistent micro–pollutants under simulated solar irradiation has been assessed. Zinc stannate (ZnSnO3), belongs to the class of ternary oxides and has a reported band gap of 2.4 eV. Due to its narrow band gap can be...Read more

Heterogeneous activation of persulfate by LaSrNiGaO3

Kouvelis K., Petala A., Bampos G., (Corresponding) Frontistis Z., Kondarides D.
Topic: 
Advanced oxidation processes
In recent years, scientists in the field of environmental management and protection, have not only detected but also quantified a large number of pharmaceuticals in treated wastewater, surface and groundwater. In order to address this problem, intensive research is carried out to develop effective...Read more

Can mixed oxides act as efficient photocatalysts for the elimination of organic water pollutants?

(Corresponding) Favier L., Sescu A., (Corresponding) HARJA M., Siamer S., Lutic D.
Topic: 
Advanced oxidation processes
New mixed-metal oxides containing zinc and lanthanum were prepared by coprecipitation. The synthesized nanocomposites were calcined, and characterized by scanning electron microscopy (SEM), X-ray diffraction, FT-IR, BET and DR analysis. The calcined sample showed a higher crystalinity, confirmed by...Read more

Removal of amoxicillin from processing wastewater by ozonation and UV-aided ozonation: a kinetic and economic comparative study

Ribeiro M., Ramos B., (Corresponding) de Castro Peixoto A.
Topic: 
Advanced oxidation processes
A novel empirical and scaling up simulation study is presented for degradation and mineralization of real residue of amoxicillin (AMX) pharmaceutical formulation in wastewater. A set of UV-ozone-based experiments was used in the kinetics modeling of AMX, considering several chemical/photochemical...Read more

EVALUATION OF PHOTOCHEMICAL DEGRADATION OF ANTIVIRAL ACYCLOVIR BY UVC/PS & UVC/H2O2 IN SYNTHETIC FRESH AND HYDROLYZED URINE

Drosou C., Tyrovola K., (Corresponding) Xekoukoulotakis N.
Topic: 
Advanced oxidation processes
The increasing presence of contaminants of anthropogenic origin in the aquatic environment raises the concern of the scientific community (Patel et al., 2019). Antiviral drugs play an important role, as their presence in aquatic bodies is associated with antiviral resistance and chronic toxicity to...Read more

Application of solar photo-Fenton oxidation coupled with granular activated carbon as a viable option for the removal of contaminants of emerging concern in the urban wastewater of India

Karaolia P., Korelidou A., (Corresponding) Fatta-Kassinos D.
Topic: 
Advanced oxidation processes
It has been estimated that approximately 62 billion litres of sewage are generated every day in India, with only 37% of sewage being treated (Saxena et al., 2021). Wastewater treatment issues such as dysfunctional UWTPs with many of them operating at low service levels compared to the design...Read more

Regeneration of dissolved Fe(II) from Fenton sludge at a microbial fuel cell using a novel biocathode

(Corresponding) Wang G., Tang K., Jiang Y., Andersen H., Zhang Y.
Topic: 
Advanced oxidation processes
Fenton reactions are widely applied for degrading recalcitrant pollutants, but the resulting ferric sludge remains a challenge. A novel concept for regenerating Fe(II) solution at pH 6 from ferric sludge generated in neutral Fenton is proposed. A microbial fuel cell (MFC) with biocathode and...Read more
