Ozonation is a water treatment process for disinfection and/or micropollutant abatement. However, ozonation of bromide-containing water leads to bromate (BrO3-) formation, a potential human carcinogen. A solution for mitigating BrO3- formation during abate ...
Bromide (Br-) levels in fresh waters range from a few ¿gL-1 to several mgL-1. In seawater its concentration is about 67 mgL-1. The goal of this thesis is to assess the fate of bromide during oxidative water treatment and to explore its influence on these t ...
Phenolic compounds are known structural moieties of natural organic matter (NOM), and their reactivity is a key parameter for understanding the reactivity of NOM and the disinfection by-product formation during oxidative water treatment. In this study, spe ...
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 ...
Disinfection is an important step in (waste)water treatment to prevent the transmission of waterborne diseases. Ozone is an effective disinfectants against all types of waterborne pathogens, including viruses. While ozone has typically been used to treat d ...
Bromide measurements and mass balances in the catchments of major Swiss rivers revealed that chemical industry and municipal waste incinerators are the most important bromide sources and account for similar to 50% and similar to 20%, respectively, of the s ...
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 ...
Bromide (Br-) is present in all water sources at concentrations ranging from similar to 10 to >1000 mu g L-1 in fresh waters and about 67 mg L-1 in seawater. During oxidative water treatment bromide is oxidized to hypobromous acid/hypobromite (HOBr/OBr-) a ...
HOBr, formed via oxidation of bromide by free available chlorine (FAC), is frequently assumed to be the sole species responsible for generating brominated disinfection byproducts (DBPs). Our studies reveal that BrCl, Br-2, BrOCl, and Br2O can also serve as ...
Virus removal and inactivation is still a major challenge for water treatment facilities in both industrialised nations and developing countries. This may seem surprising as chlorine disinfection started to spread broadly over a century ago. However, many ...
