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:

Removal of emerging pollutants from aquatic system using electrochemical treatment and adsorption: Comparison and analysis
TL;DR: In this paper, a three-dimensional electrochemical reactor with particle electrodes such as Strychnos potatorum was used to treat the emerging pollutants such as metronidazole, chloramphenicol and sulphonamide.
Journal ArticleDOI
Degradation of naproxen in chlorination and UV/chlorine processes: kinetics and degradation products
TL;DR: The results showed that both chlorination and UV/chlorine disinfection could remove NAP effectively, and the reactive radicals dominated in NAP degradation in alkaline solutions, while chlorination dominated in acidic conditions.
Dissertation
Degradation of organic micropollutants using a hybrid bioreactor
TL;DR: In this article, a methodologie proposee a repose sur la mise en place de tests de biodegradation en batch afin de selectionner des microorganismes pertinents for the degradation des molecules cibles, avant de travailler avec un bioreacteur hybride.

TL;DR: The concentration of 4-acetyl amino antipyrine was the highest among the metabolites determined in the water samples ranging from 0.27 to 5.72μg − − 3 as mentioned in this paper.
Journal ArticleDOI
Enhanced effect of pyrite on the removal of metronidazole by zero valent iron.
TL;DR: In this paper, a dual ZVI/pyrite system consisting of ZVI (1.0 ) and pyrite (4.0 ), which was not reactive for MNZ removal, was simply mixed with zero valent iron (ZVI) to efficiently remove metronidazole (MNZ) in anaerobic aqueous solutions.

TL;DR: Present knowledge does not reveal if regular therapeutic use may be the source of a substance carried by sewage effluent into the aquatic system, even though clofibrate, a lipid lowering agent, has been identified in ground and tap water samples from Berlin.
Journal ArticleDOI
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.
