Kinetics of the reaction between hydrogen peroxide and aqueous iodine: Implications for technical and natural aquatic systems

Urs von Gunten, Jaedon Shin

Oxidative treatment of iodide-containing waters can lead to a formation of potentially toxic iodinated disinfection byproducts (I-DBPs). Iodide (I-) is easily oxidized to HOI by various oxidation processes and its reaction with dissolved organic matter (DO ...

Mixture effects of drinking water disinfection by-products: implications for risk assessment

Urs von Gunten

Disinfection by-products (DBPs) in drinking water have been associated with increased cancer risk but single DBPs cannot explain epidemiological cancer occurrences. To test if combined effects of DBPs are plausible to explain epidemiological evidence for a ...

Linking transformations of organic carbon to post-treatment performance in a biological water recycling system

Odile Marie Clotilde Hervás de Nalda-Larivé

Ozone, electrolysis and granular activated carbon (GAC) were examined as potential post-treatments to followa household-scale biologically activated membrane bioreactor (BAMBi), treating a wash water containing trace urine and feces contamination. Each pos ...

Solar-Electrochemical Platforms for Sodium Hypochlorite Generation in Developing Countries

Demetri Psaltis, Christophe Moser, Seyyed Mohammad Hosseini Hashemi, Enrico Chinello

On-site generation of sodium hypochlorite (NaClO) holds the potential to bring an efficient and cost-effective water disinfection method to isolated and remote locations. Solar-driven, stand-alone reactors could provide those communities full independence ...

Seasonal and spatial variation in total trihalomethane formation potential in groundwater in Tulkarm and Hebron, Palestine

Loay Awad

Water disinfection using processes such as chlorination is required to kill bacteria and harmful biological components. During chlorination, organic components in water react with chlorine, forming harmful disinfection by-products such as trihalomethanes ( ...

Comparing the anti-bacterial performance of chlorination and electrolysis post-treatments in a hand washing water recycling system

Odile Marie Clotilde Hervás de Nalda-Larivé

Innovative solutions are necessary to enable the decentralized recycling of greywater for applications requiring high-quality water, such as hand washing. While physical barriers such as ultrafiltration membranes effectively prevent the passage of bacteria ...

Kinetic and mechanistic aspects of selenite oxidation by chlorine, bromine, monochloramine, ozone, permanganate, and hydrogen peroxide

Urs von Gunten

Selenium (mainly in the forms of selenite (Se(IV)) and selenate (Se(VI)) is a regulated drinking water contaminant, but there is little information on the kinetics and mechanisms of Se(IV) oxidation during water treatment. Species-specific and apparent sec ...

Hydraulic Reconstruction of the 1818 Gietro Glacial Lake Outburst Flood

Christophe Ancey, Eric Bardou, Tomás Alfredo Trewhela Palacios

In the spring of 1818, ice avalanches from the Gietro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25x10(6) m(3). Cantonal authorit ...
