Application of Computational Fluid Dynamics in Chlorine-Dynamics Modeling of In-Situ Chlorination Systems for Cooling Systems

Applied Sciences, 2020
Chlorination is the preferred method to control biofouling in a power plant cooling system due to its comparative effectiveness and low cost. If a power plant is located in a coastal area, chlorine can be electrochemically generated in-situ using ...

Comparison of chlorine decay models under varying temperature and UV254 for water supply

Results in Engineering
Bulk chlorine decay in water distribution systems is strongly influenced by temperature and organic matter. Higher temperatures accelerate chlorine decay reactions, while organic matter acts as a primary reactive substance.

Modeling Chlorine Decay in Surface Water [PDF]

Journal of Environmental Informatics, 2003
Chlorination is the most widely practiced form of disinfection in the US. However, there is concern that the disinfection by-products (DBPs) formed during chlorination might be carcinogenic. Because of this increasing concern in water supply systems, there is a need for models that can be used to predict chlorine residuals and optimize the disinfection

Application of black-box models based on artificial intelligence for the prediction of chlorine and TTHMs in the trunk network of Bogotá, Colombia

Journal of Hydroinformatics, 2023
The chlorine and total trihalomethane (TTHM) concentrations are sparsely measured in the trunk network of Bogotá, Colombia, which leads to a high uncertainty level at an operational level.
