Journal ArticleDOI
A tale of two treatments: the multiple barrier approach to removing chemical contaminants during potable water reuse
TL;DR: New policies are needed to prevent chemicals that are difficult to remove during advanced treatment from entering the sewer system and using knowledge about the composition of municipal wastewater and the mechanisms through which contaminants are removed during treatment should be possible to safely reuse municipal wastewater effluent as a drinking water source.
Journal ArticleDOI
Enhanced transformation of sulfonamide antibiotics by manganese(IV) oxide in the presence of model humic constituents.
TL;DR: In this study, a manganese(IV) oxide-mediator (MnO2) system for the abatement of sulfonamide antibiotics was evaluated and cross-coupling products from sulfamethoxazole (SMX) with oxidized SA were formed in the MnO2-SA system.
Journal ArticleDOI
Proxies to monitor the inactivation of viruses by ozone in surface water and wastewater effluent.
TL;DR: It is confirmed that ozone is a highly effective disinfectant for viruses in both surface water and wastewater, and that the abatement of UV254 and CBZ can be used to track virus inactivation during water and Wastewater treatment.
Journal ArticleDOI
Kinetic and mechanistic aspects of selenite oxidation by chlorine, bromine, monochloramine, ozone, permanganate, and hydrogen peroxide.
Shaogang Liu,Shaogang Liu,Shaogang Liu,Elisabeth Salhi,Wanting Huang,Kaisheng Diao,Urs von Gunten,Urs von Gunten +7 more
TL;DR: The oxidation of Se(IV) by chlorine and ozone were successfully predicted in a natural water by a kinetic model and the reaction orders and stoichiometries, the corresponding Se( IV) oxidation mechanisms for various oxidants are discussed.
Journal ArticleDOI
Laser flash photolysis study of the photoinduced oxidation of 4-(dimethylamino)benzonitrile (DMABN)
Frank Leresche,Frank Leresche,Lucie Ludvíková,Dominik Heger,Petr Klán,Urs von Gunten,Urs von Gunten,Silvio Canonica +7 more
TL;DR: Laser flash photolysis investigations aimed at characterizing the photoinduced, aqueous phase one-electron oxidation of 4-(dimethylamino)benzonitrile (DMABN) as a representative of this contaminant class confirmed the production of the radical cation of DMABN (D MABN˙+) after direct photoexcitation of D MABN at 266 nm in accord with previous experimental results.
