For example, in general THM formation increases with an increase in pH but the effects are reversed for HAA5. Temperature has a positive effect on DBP formation potential, and increases the rate of reaction (Amy et al., 1987a; US EPA, 2001b).

WebNov 23, 2011 · First, the formation pathways of the N-DBP families are partially linked because most of the pathways involve similar amine precursors. Second, it is unlikely that a disinfection scheme that is free of byproduct formation will be discovered.
