What is DBP formation potential (dbpfp)?
DBP formation potential (DBPFPs) experiments are designed to maximize reactions between the precursors and disinfectant (e.g., Krasner et al., 2008). With knowledge of trends between precursors and DBPFP, unit processes capable of reducing more important precursors can be employed to reduce overall DBP levels in treated water.
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 is a DBP FP test?
DBPs that are originally present in drinking water sources and DBP precursors determined using DBP FP tests can potentially be used to trace the origins of DOM in drinking water sources and evaluate the impacts of natural or anthropogenic events on source water quality.
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.
Can disinfection byproduct (DBP) formation potential be evaluated?
Disinfection Byproduct (DBP) Formation Potential. Two approaches were described in the selected articles to evaluate DBP formation, which are fully reported in SI, Extracted Data.
