A Pragmatic Approach for Chlorine Decay Modeling in Multiple-Source Water Distribution Networks Based on Trace Analysis

Water
Providing water with adequate quality to users is one of the main concerns for water utilities. In most countries, this is ensured through the introduction of disinfectants, such as chlorine, which are subjected to decay over time, with consequent loss ...

Discovery of the Isotopes with 11 <= Z <= 19

, 2011
A total of 194 isotopes with 11 $\le$ Z $\le$ 19 have been identified to date. The discovery of these isotopes which includes the observation of unbound nuclei, is discussed.

Mass transfer of solutes in turbulent wall bounded flows reacting with the conduit surface

, 2011
This thesis focuses on the decay of chlorine in pipes of drinking water distribution networks due to wall and bulk demand. Accurate prediction of chlorine decay is important, as both chlorine concentrations which are too low and too high pose serious ...

Impact of Booster Chlorination on Chlorine Decay and THM Production: Simulated Analysis

Journal of Environmental Engineering, 2009
The effect of conventional and booster chlorination on chlorine residuals and trihalomethane (THM) formation in drinking water distribution systems was modeled using the EPANET hydraulic modeling software. The model results suggest that booster chlorination may allow utilities to meet disinfection goals better by carrying chlorine residuals to remote ...
