Modeling the fate of disinfection by-products in water distribution systems

Chlorine-based disinfection agents are known to favor the production of Disinfection By-Products (DBPs), whose concentrations are restricted by international guidelines to ensure a safe consumption of drinking water. Hence, it is important to understand the behavior of DBPs within Water Distribution Networks (WDNs) to avoid exposure of WDN users to concentrations higher than guideline values. The buildup in chlorate concentration resulting from disinfectant reaction is here simulated with EPANET for two hypothetical WDNs. Results indicate that increases in chlorate concentrations within the WDN are very limited (
