PREDICTING THE FORMATION OF ALDEHYDES AND BOM

This research attempted to (1) identify water Quality and water treatm ent parameters that can potentially influence the creation of biodegra dable organic matter (BOM) and aldehydes and (2) derive correlations o f BOM (estimated by measuring assimilable organic carbon [AOC] and bio degradable dissolved organic carbon [BDOC]) and aldehydes, with ozone dosage and water quality variables, through multiple regression analys is. Aldehyde formation was influenced by ozone dosage, alkalinity, non humic fraction of DOG, chlorophyll a, and DOG. Ozonated water BDOC lev el was a function of raw water BDOC concentration and ozone dosage, wh ereas AOC concentration in ozonated water was related to raw water AOC level, alkalinity, and ozone dosage. Multiple regression analysis sho wed good correlations of AOC, BDOC, and aldehydes with the variables l isted.
