Modelling of Micropollutant Removal by Ozonation and Chlorination in Potable Water Treatment
In regards of increasingly stringent rules on toxicity, prediction engines for potable water treatment have become a necessity. This particularly applies to oxidation steps, where micropollutants should be removed and where potentially harmful by-products may be formed, and has therefore lead to the building up of a new simulator for both chlorination and ozonation. This first report aims at gi...
متن کاملDisinfectant decay and disinfection by-products formation model development: chlorination and ozonation by-products.
Comprehensive disinfectant decay and disinfection by-product formation (D/DBP) models in chlorination and ozonation were developed to apply to various types of raw and treated waters. Comparison of several types of models, such as empirical power function models and empirical kinetic models, was provided in order to choose more robust and accurate models for the D/DBP simulations. An empirical ...
متن کاملHigh Resolution Mass Spectrometry Elucidation of Captopril’s Ozonation and Chlorination By-Products
The article evaluated the degradation of the captopril in aqueous solution after ozonation and chlorination. The process was continuously monitored focusing on the identification, mass spectrometry and elucidation of its by-products by applying direct infusion and high performance liquid chromatography, electrospray ionization high resolution mass spectrometry, in the negative ion mode. The cyt...
متن کاملEffects of ozonation on disinfection byproduct formation and speciation during subsequent chlorination.
Ozone has been widely used for drinking water treatment recently. This study was conducted to investigate the effect of dosing ozone on the formation potentials and speciation of disinfection by-products (DBPs, brominated DBPs in particular) during subsequent chlorination. Trihalomethanes (THMs), trihaloacetic acids (THAAs), dihaloacetic acids (DHAAs), dihaloacetonitriles (DHANs), chloral hydra...
متن کاملModeling Micropollutant Removal by Ozonation and Chlorination in Potable Water Treatment
Having set general frames for our study [Mandel, 2007] and our software, SimOx, [Mandel et al., 2008] in previous publications, this report aims at giving a brief overview of the experimental part of the research done in 2008. The experiments were divided in two periods: from January to June and from October to the end of the year. During the first period, results were collected to validate a p...
