Residual chlorine decay in a broad, shallow river
Water Research, 1993Abstract Field investigations into the mixing and decay of discharge plumes containing total residual chlorine (TRC) concentrations of 2.0 mg/l were conducted in the North Saskatchewan River downstream from two water treatment plants in the City of Edmonton, Canada.

Realistic numerical simulation of chlorine decay in pipes
Water Research, 1998The objective of the present study is to develop a numerical mass transport model that can simulate chlorine disappearance mechanisms under low flow conditions. The model accounts for axial convection and radial diffusion in a pipe under turbulent, transitional and laminar flow regimes and uses realistic velocity profiles.

Modelling chlorine residual decay as influenced by temperature
Water and Environment Journal, 2015AbstractTemperature is one of the most important factors affecting chlorine decay rates in drinking water systems. In this article, temperature effect on chlorine decay rates in raw and treated waters was studied. Results show that temperature affects differently the fast and slow decay phases, the latter being more sensitive to temperature variations,

Modelling of chlorine decay in municipal water supplies
Water Research, 1999Abstract This paper describes the effects which temperature and the initial chlorine concentration have on the chlorine decay in different water samples. It also reports the derivation of empirical formulae which describe these effects. The data show that chlorine decays more rapidly in fresh samples than in those which had been re-chlorinated with ...

Relationship of chlorine decay and THMs formation to NOM size
Journal of Hazardous Materials, 2003Because of increasing concern about balancing health risks for pathogen control and disinfection by-product (DBP) formation in water supplies, utilities are forced to closely examine and optimize their disinfection practices. A better understanding of the relationship between the molecular weights of the natural organic matter (NOM), chlorine decay ...

A new approximate solution for chlorine concentration decay in pipes
Water Research, 2008Biswas et al. (1993. A model for chlorine concentration decay in pipes. Water Res. 27(12), 1715-1724) presented an analytical solution of a two-dimensional (2-D) steady-state chlorine transport equation in a pipe under the turbulent condition and employed fractional error function and regression technique to develop an approximate solution.

Science of The Total Environment
Chlorination is the most widely used disinfection technology due to its simplicity and continuous disinfection ability. However, the drawbacks of disinfection by-products and chlorine-resistant bacteria have gained increasing attention. Nowadays, ferrate (Fe(VI)) is a multifunctional and environmentally friendly agent which has great potential in ...
