How do nom characteristics affect DBP formation?
This study investigated the relationships among NOM characteristics, such as molecular weight (MW), fluorescence, and chemical composition, with DBP formation resulting from the chlorination of relatively high and low SUVA precursors.
What is the role of DBP precursors in water treatment?
Understanding the diverse nature of DBP precursors is critical for developing more effective water treatment strategies. This includes not only optimizing the disinfection process to minimize DBP formation but also implementing pre-treatment measures to reduce the concentration of precursors in the water.
What is a DBP disinfection byproduct?
DBPs are generally formed by the reaction of disinfectants such as chlorine with organic precursors present in source water; these organic precursors are mainly called natural organic matter (NOM) and NOM acts as a forerunner to DBPs. Some of the chlorination disinfection byproducts are shown in Table 1.
Are disinfection by-products (DBPs) formed during water treatment a problem?
Disinfection by-products (DBPs) formed upon water treatment is an emerging issue worldwide. While monitoring of DBP precursors can easily be achieved for high specific UV absorbance (SUVA) organic (>6 L/mg·m), low and extremely low SUVA precursors (<2 L/mg·m) are difficult to monitor or even to predict their DBP formation behaviour.
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 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.
