Reaeration Model for a Still-Water Body
Publication: Journal of Environmental Engineering
Volume 141, Issue 1
Abstract
An investigation on the influence of temperature (21.6–39.6°C) on the reaeration rate was performed. The recipient still water body was homogeneous and unstratified. The findings of the experimental study showed that the reaeration rate increases with temperature within the range of the temperature investigated. A mathematical model for estimating the reaeration rate is also presented. A new temperature correction factor for the conversion of the kinetic rate coefficient at different temperatures has been developed and was found to better reflect the reaction rates associated with the reaeration process.
