Genotypic, phenotypic and mechanistic insights into viruses with resistance to common water disinfectants

Qingxia Zhong

Infectious diseases caused by waterborne viruses contribute to the global disease burden. An effective barrier to prevent the discharge of waterborne viruses is a disinfection step, yet disinfection is not always efficient at inactivating viruses. This the ...

Study of Hypochlorite Reduction Related to the Sodium Chlorate Process

Michael Markus Busch

Reduction of hypochlorite is the most important side reaction in the sodium chlorate reactor leading to high energy losses. Today chromate is added to the reactor solution to minimize the hypochlorite reduction but a replacement is necessary due to health ...

Determining The Potential Of Salinity Gradient Energy Source Using An Exergy Analysis

Mixing of fresh (river) water and salty water (seawater or saline brine) in a control fashion would produces an electrical energy known as salinity gradient energy (SGE). Two main conversion technologies of SGE are membrane-based processes; pressure retard ...

Solid oxide fuel cell anode degradation by the effect of hydrogen chloride in stack and single cell environments

Christian Ludwig, Jan Van Herle, Stefan Diethelm, Hossein Madi

The poisoning effect by hydrogen chloride (HCl) on state-of-the-art Ni anode-supported solid oxide fuel cells (SOFCs) at 750 degrees C is evaluated in either hydrogen or syngas fuel. Experiments are performed on single cells and short stacks and HCl concen ...

Determinants of disinfectant pretreatment efficacy for nitrosamine control in chloraminated drinking water

Urs von Gunten

Utilities using chloramines need strategies to mitigate nitrosamine formation to meet potential future nitrosamine regulations. The ability to reduce NDMA formation under typical post-chloramination conditions of pretreatment with ultraviolet light from a ...

Benchmark thermochemistry of chloramines, bromamines, and bromochloramines: Halogen oxidants stabilized by electron correlation

Jeremy Samuel Arey, Daniela Trogolo

Chloramines, bromamines, and bromochloramines are halogen-containing oxidants that arise from the reaction of hypohalous acids with ammonia in water. Although relevant to both water disinfection chemistry and biochemistry, these molecules are difficult to ...

Electrochemical Detection of Free Chlorine at Inkjet Printed Silver Electrodes

Hubert Girault, Fernando Cortes Salazar, Andreas Stephan Lesch, Milica Jovic, Véronique Amstutz, Hongyan Bi

A low-cost, reliable and sensitive electrochemical method for free chlorine analysis in water using inkjet printed silver electrodes is presented. Free chlorine detection was based on linear sweep voltammetry (LSV) analysis of AgCl/Ag2O films formed over a ...
