Combination of Advanced Oxidation Processes and biological treatments for wastewater decontamination—A review
TL;DR: The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation.

Photoelectrochemistry of oxalate on particulate TiO2 electrodes
John Byrne,Brian R. Eggins +1 more
TL;DR: In this article, the effects of electron acceptors, i.e., oxygen and Fe3+, on the rate of mineralisation of oxalate were determined, and significant increases in the short-circuit photocurrent densities were observed upon the addition of Oxalate to the anode compartment when oxygen was present only in the cathode compartment.

Degradation of the herbicide tebuthiuron using solar photo-Fenton process and ferric citrate complex at circumneutral pH
TL;DR: In this paper, the influence of pH on the degradation of the herbicide tebuthiuron (TBH) was investigated using in situ generated Fe(III)-citrate complexes (Fe:cit) submitted to the photo-Fenton process under solar irradiation.
Journal ArticleDOI
Effects of experimental conditions on E. coli survival during solar photocatalytic water disinfection
TL;DR: It was found that bacterial viability in the reactor strongly depends on all the parameters examined, so that disinfection and dark inactivation overlap when working under low-osmolarity conditions and low bacterial concentrations.
