While drinking water disinfection has effectively prevented waterborne diseases, an unintended consequence is the generation of disinfection byproducts (DBPs).
Urban stormwater discharge is known to be an important source of DOM, impacting the characteristics of DOM in downstream surface waters and the formation of associated DBP during drinking water disinfection [8], [9], [18], [33], [44], [50].It has been demonstrated that rainfall events can considerably enhance the organic carbon reactivity of filtered surface waters,
- How are DBPs formed from different disinfection agents?
- The formation of DBPs from various disinfection agents has been previously compared , . In general, each disinfectant tends to form its own suite of DBPs, with some overlap of DBPs among different disinfectants . Free chlorine mainly produces THMs and HAAs, and chloramines could also lead to the formation of iodinated DBPs and NAs.
- How are DBP precursors determined?
- In general, DBP precursors in drinking water sources can be determined using DBP FP tests, in which source water samples are dosed with a stoichiometric excess of specific disinfection agents (e.g., chlorine or chloramines) for a reaction time that is designed to maximize DBP formation under certain reaction conditions , .
- How do DBPs form?
- Unlike most other drinking water contaminants, DBPs form from disinfectant application within the plant, as a result of the final drinking water treatment process (disinfection) and continue to form throughout the distribution system, such that control strategies necessarily focus on minimizing their formation.
- What are disinfection byproducts (DBPs)?
- However, current analysis approaches are not ideal, as they tend to be laborious, time-consuming, or technically difficult. Disinfection byproducts (DBPs) are a family of well-known secondary pollutants formed by the reactions of chemical disinfectants with DBP precursors during water disinfection treatment.
- What causes increased DBP precursors in surface water?
- Both dry (i.e., particulate and gaseous deposition) and wet depositions (i.e., precipitation such as rain and snow) can contribute to an increase in DBP precursors in surface water , , .
- Does seasonality affect DBP formation potential of an interconnected River-Reservoir natural system?
- This research presents the spatial and seasonal effects on DBP formation potential of an interconnected river-reservoir natural system. Results show that while spatial variability including depth is insignificant, seasonality is the main driver of the observed variability.
