TLDR
The results showed that paraxanthine, caffeine and acetaminophen were the main individual pollutants usually found in concentrations over 20 ppb, and the hydroxyl radical reaction was the major pathway for the oxidative transformation of these compounds.About:

Nonradical transformation of sulfamethoxazole by carbon nanotube activated peroxydisulfate: Kinetics, mechanism and product toxicity
TL;DR: In this paper, the transformation of sulfamethoxazole (SMX) by peroxydisulfate (PDS) activated with one multi-walled carbon nanotube (CNT) via a non-radical pathway was examined, and the underlying reaction mechanism was explicated.

Micropollutants removal from secondary-treated municipal wastewater using weak polyelectrolyte multilayer based nanofiltration membranes
S. Mehran Abtahi,S. Mehran Abtahi,Shazia Ilyas,Claire Joannis Cassan,Claire Albasi,Wiebe M. de Vos +5 more
TL;DR: In this article, a hollow fiber dense ultrafiltration (UF) membrane was used to remove micropollutants (MPs) from municipal wastewater using layer by layer (LbL) deposition of weak polycation poly(allylamine hydrochloride) (PAH) and weak polyanion poly(acrylic acid) (PAA) on the surface of the UF membrane.

Enantioselective biodegradation of pharmaceuticals, alprenolol and propranolol, by an activated sludge inoculum.
TL;DR: This work presents the biodegradation of alprenolol and propranolol using an activated sludge inoculum, monitored by a validated enantioselective HPLC method with fluorescence detection, and indicated slightly higher biodegrading rates for the S-enantiomers of both beta-blockers.
Journal ArticleDOI
Application of solar photocatalytic ozonation for the degradation of emerging contaminants in water in a pilot plant
TL;DR: In this paper, the authors compared different solar-driven photochemical processes including photolysis, photocatalytic oxidation with Fe(III) or TiO2, photo-Fenton and single, photolytic and photocatallytic ozonations in a compound parabolic collector photoreactor.
Journal ArticleDOI
Fenton Technology for Wastewater Treatment: Dares and Trends
TL;DR: In this article, the authors present a discussion of the restrictions of Fenton reaction and the fresh manners for dealing with them and this work focuses on its main findings, such as the necessity of acidic pH circumstance, the formation of iron sludge and the need for elevated chemical introductions.

Occurrence of drugs in German sewage treatment plants and rivers
TL;DR: In this article, the occurrence of 32 drug residues belonging to different medicinal classes like antiphlogistics, lipid regulators, psychiatric drugs, antiepileptic drugs, betablockers and β 2 -sympathomimetics as well as five metabolites has been investigated in German municipal sewage treatment plant (STP) discharges, river and stream waters.

A review of imperative technologies for wastewater treatment I: oxidation technologies at ambient conditions
TL;DR: In this article, the authors highlight five different oxidation processes operating at ambient conditions viz. cavitation, photocatalytic oxidation, Fenton's chemistry, ozonation, and use of hydrogen peroxide.

Oxidation of pharmaceuticals during ozonation and advanced oxidation processes
TL;DR: It could be shown that the second-order rate constants determined in pure aqueous solution could be applied to predict the behavior of pharmaceuticals dissolved in natural waters.
