||The paper summarizes several recent studies on the impact of ozonation and biological treatment on DBP formation. Ozonation was characterized by the formation of ozonation DBPs such as aldehydes, assimilable organic carbon (AOC), biodegradable dissolved organic carbon (BDOC) and the oxidation of bromide to bromate. The oxidation of the DBP precursor compounds and the effectiveness of biotreatent for the control of DBPs were monitored by the formation potential (FP) for total organic halogen (TOX), total THMs (TTHMs) and total measured haloacetic acid (THAAs). Special attention was also given to the impact of bromide concentration on the speciation of the DBPs. A specific objective of the paper was to compare DBP control by batch biological treatment at the bench-scale to that by a continuous flow sand filter at the pilot-scale.
