would inevitably lead to an increased potential for DBP formation. Dissolved organic nitrogen (DON) is an important indicator of the presence of organic nitrogen compounds in DOM [22].
DBP formation potential tests were conducted to evaluate the maximum DBP formation ability of the water samples. Free chlorine was used as the disinfectant in DBPFP

Given that source water is a highly complex matrix, it is technically infeasible to identify and quantify all the water constituents. However, studies on DBPs and DBP
formation potential of DBPs was performed and the existing process for ERA was evaluated. The results show knowl‑ edge gaps on the formation of DBP in non‑aqueous systems and DBP

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. The
In order to determine the nature of the organic matter contributing to DBPs, DBP formation potential was compared with standard water quality parameters such as UV-254, color and dissolved organic carbon (DOC), as well as pyrolysis-gas chromatography/mass spectrometry (GC/MS). Results showed strong correlations between UV-254 and DBP formation
- 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 , .
- What factors affect DBP formation?
- However, technological parameters (e.g., contact time, chlorine dosage, and bromide to residual free chlorine ratio) of the two chlorination procedures are different, which can lead to differences in DBP formation.
- Do organic DBP concentrations exceed EU parametric values?
- None of the measured organic DBP concentrations exceeded the EU parametric values at any point of the water treatment . The observed concentrations varied between sites and between BC and disinfection. At site I, every DBP class was generated in higher concentration during disinfection, than during BC (Figure 2).
- 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.
- How does Doc affect DBP formation?
- Comparing the sites, during BC, higher DBP formation was observed at II and III where DOC concentrations in the raw water are higher. During disinfection, the effect was reversed: at site I, where DOC is much lower, concentrations of the formed DBPs exceeded the values measured at the other two sites (Figure 2).
