Implications of sequential use of UV and ozone for drinking water quality
Urs von Gunten, Silvio Canonica
The formation of bromate levels exceeding the drinking water standard of 10 mu g L-1 may impose the reduction of ozone doses used in the treatment of drinking water. This paper illustrates the procedure of evaluating the use of reduced ozone doses while im ...
2006Solar disinfection of water by photocatalytic processes
Chlorine, widely used as a disinfectant for drinking water production, is known to interact with organic matter to yield disinfection by-products (DBPs). Some of these compounds, as the trihalomethanes, are highly toxic for human health. Alternative disinf ...
EPFL2005Field solar E-coli inactivation in the absence and presence of TiO2: is UV solar dose an appropriate parameter for standardization of water solar disinfection?
Evaluation of solar treatment in the absence and presence of TiO2 has been made to assess its effectiveness in reducing bacterial load with respect to drinking water standards. Field experiments under direct solar radiation were carried out using a compoun ...
2004Oxidation of pharmaceuticals during ozonation and advanced oxidation processes
Urs von Gunten, Silvio Canonica
This study investigates the oxidation of pharmaceuticals during conventional ozonation and advanced oxidation processes (AOPs) applied in drinking water treatment. In a first step, second-order rate constants for the reactions of selected pharmaceuticals w ...
2003MTBE oxidation by conventional ozonation and the combination ozone/hydrogen peroxide: Efficiency of the processes and bromate formation
The present study investigates the oxidation of methyl tert-butyl ether (MTBE) by conventional ozonation and the advanced oxidation process (AOP) ozone/hydrogen peroxide under drinking water treatment conditions. The major degradation products identified w ...
