Full Description

The objective of this research was to investigate the nature of biodegradable organic matter (BDOM) from source waters. Thebiological potential for degradation of dissolved organic carbon was determined by analyzingassimilable organic carbon (AOC) and BDOC for all untreated test waters, as well as the three major natural organic matter (NOM) pools after theirfractionation; humics (hydrophobic fraction (HPO)), acylheteropolysaccharides (high molecularweight fraction (HMW)) and simple plant products (hydrophilic fraction (HPI)). This testing wasextended to fractions treated with chlorine and ozone. The purpose of the latter was to provide anindication of the presence of compounds that may not themselves be biodegradable, but couldreact in treatment systems to form biodegradable substances. Numerous studies have shown that ozonation and chlorination can increase the biodegradabiltiy of NOM present in a drinking watersystem. Includes 6 references, table, figures.
