- •
The Cl2–NH2Cl process formed more haloacetamides (HAcAms) and haloacetonitriles (HANs) than the Cl2 and NH2Cl processes.
- •
Bromine substitution factors (BSFs) of dihaloacetamides (DHAcAms) were higher than those of dihaloacetonitriles (DHANs).
- •
The order for the BSFs of DHAcAms and DHANs from highest to lowest was: Cl2 process, Cl2–NH2Cl process, and NH2Cl process.
- •
The Cl2+NH3 process formed more disinfection by-products than the NH3+Cl2 process for in situ chloramination.
