Echovirus 11 mutants with increased resistance to common water disinfectants

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong

Common water disinfectants like chlorine have been reported to select for resistant viruses. Yet, only little attention has been devoted to characterizing disinfection resistance. The goal of this study was to produce disinfectant-resistant viruses and to ...

On the relationship between total ozone and atmospheric dynamics and chemistry at mid-latitudes - Part 1: Statistical models and spatial fingerprints of atmospheric dynamics and chemistry

Anthony Christopher Davison, Linda Frossard

We use statistical models for mean and extreme values of total column ozone to analyze "fingerprints" of atmospheric dynamics and chemistry on long-term ozone changes at northern and southern mid-latitudes on grid cell basis. At each grid cell, the r-large ...

Process Control For Ozonation Systems: A Novel Real-Time Approach

Urs von Gunten

For real-time control of ozonation processes in water works, a sequencing batch reactor was constructed to measure the ozone decay rate constant (k(O3)) in short time intervals of about 15 min. The batch reactor is filled during the production process, imm ...

Experimental study on flow boiling heat transfer of multiport tubes with R245fa and R1234ze(E)

John Richard Thome, Bruno Agostini, Farzad Vakili Farahani

The upward flow boiling experiments were carried out in a flat aluminum extruded multiport tube, which is composed of 7 parallel rectangular channels (1.1 mm × 2.1 mm) with hydraulic diameter of 1.4 mm. Two refrigerants, R245fa and R1234ze, the latter a re ...

Enhanced N-nitrosamine formation in pool water by UV irradiation of chlorinated secondary amines in the presence of monochloramine

Urs von Gunten, Minju Lee, Silvio Canonica

N-Nitrosamines, in particular N-nitrosodimethylamine (NDMA), are carcinogens, which occur as chlorine disinfection by-products (DBPs) in swimming pools and hot tubs. UV treatment is a commonly used technique in swimming pools for disinfection and DBP atten ...

Kinetic assessment and modeling of an ozonation step for full-scale municipal wastewater treatment: Micropollutant oxidation, by-product formation and disinfection

Urs von Gunten, Juliane Hollender, Hansruedi Siegrist

The kinetics of oxidation and disinfection processes during ozonation in a full-scale reactor treating secondary wastewater effluent were investigated for seven ozone doses ranging from 0.21 to 1.24 g O-3 g(-1) dissolved organic carbon (DOG). Substances re ...

Palladium-catalyzed desulfinylative C–C allylation of Grignard reagents and enolates using allylsulfonyl chlorides and esters

Pierre Vogel, Chandra Mouleeswara Rao Volla

2-Methylprop-2-ene-, prop-2-ene-, 1-methylprop-2-ene-, and (E)-but-2-enesulfonyl chlorides have been used as electrophilic partners in desulfinylative palladium- catalyzed C–C coupling with Grignard reagents and sodium salts of dimethyl malonate and methyl ...

Elimination of Organic Micropollutants in a Municipal Wastewater Treatment Plant Upgraded with a Full-Scale Post-Ozonation Followed by Sand Filtration

Urs von Gunten, Juliane Hollender, Hansruedi Siegrist

The removal efficiency for 220 micropollutants was studied at the scale of a municipal wastewater treatment plant (WWTP) upgraded with post-ozonation followed by sand filtration. During post-ozonation, compounds with activated aromatic moieties, amino func ...

Ozonation and advanced oxidation of wastewater: Effect of O-3 dose, pH, DOM and HO center dot-scavengers on ozone decomposition and HO center dot generation

Urs von Gunten

The decomposition of ozone in wastewater is observed starting 350 milliseconds after ozone addition. It seems not to be controlled by the autocatalytic chain reaction, hut rather by direct reactions with reactive moieties of the dissolved organic matter (D ...
