Predicting the formation of aldehydes and BOM

Water quality and treatment parameters that can potentially influence the creation of biodegradable organic matter (BOM) and aldehydes were identified. In addition, correlations were derived of BOM (estimated by measuring assimilable organic carbon (AOC) and biodegradable dissolved organic carbon (BDOC)) and aldehydes, with ozone dosage and water quality variables, through multiple regression analysis. Aldehyde formation was influenced by ozone dosage, alkalinity, nonhumic fraction of DOC, chlorophyll-a, and DOC. Ozonated water BDOC level was a function of raw water BDOC concentration and ozone dosage, whereas AOC concentration in ozonated water was related to raw water AOC level, alkalinity and ozone dosage.
