Formation of disinfection by-products during ballast water treatment with ozone, chlorine, and peracetic acid: influence of water quality parameters

Urs von Gunten

As ocean-going ships begin implementing chemical disinfection to treat ballast water, the potential formation of disinfection by-products (DBPs) is an important issue of concern. This is especially critical since ballast waters are often saline, and the in ...

Peracetic Acid Oxidation of Saline Waters in the Absence and Presence of H2O2: Secondary Oxidant and Disinfection Byproduct Formation

Urs von Gunten

Peracetic acid (PAA) is a disinfectant considered for use in ballast water treatment, but its chemical behavior in such systems (i.e., saline waters) is largely unknown. In this study, the reactivity of PAA with halide ions (chloride and bromide) to form s ...

Comparison of a novel extraction-based colorimetric (ABTS) method with membrane introduction mass spectrometry (MIMS): Trichloramine dynamics in pool water

Urs von Gunten, Silvio Canonica

Trichloramine is a hazardous disinfection by-product, which is present in chlorinated swimming pools. Although it is primarily taken up by inhalation, the concentration in pool water is important to monitor pool water quality and to assess trichloramine mi ...

An experimental and constitutive investigation on the chemo-mechanical behaviour of a clay

Lyesse Laloui, Alessio Ferrari, Paul Joost Witteveen

Engineering issues for which the understanding of the chemo-mechanical behaviour of soils is relevant include wellbore stability problems, the salinification of groundwater, and nuclear waste storage. However, despite the vast number of situations in which ...

Photolysis of inorganic chloramines and efficiency of trichloramine abatement by UV treatment of swimming pool water

Urs von Gunten, Silvio Canonica

Trichloramine, one of the three inorganic chloramines (mono-, di- and trichloramine), is a problematic disinfection by-product in recreational pool water since it causes skin and eye irritations as well as irritations of the respiratory tract. The most com ...

Elucidating bacterial regrowth: Effect of disinfection conditions in dark storage of solar treated secondary effluent

César Pulgarin, Stefanos Giannakis

In this study, we systematically investigate solar disinfection of synthetic secondary wastewater, with the effort to decrypt the effects disinfection conditions have on post-irradiation bacterial regrowth in the dark. A full factorial design of 240 experi ...

Chemo-mechanical behaviour of a low activity clay

Lyesse Laloui, Alessio Ferrari, Paul Joost Witteveen

Environmental geotechnics involves several engineering applications (such as the salinification of groundwater and the storage of nuclear wastes) for which a deep understanding of the chemo-mechanical behaviour of soils is a fundamental component. Despite ...
