Balancing Bromate Formation, Organics Oxidation, and Pathogen Inactivation: The Impact of Bromate Suppression Techniques on Ozonation System Performance in Reuse Waters
… is effective for pathogenic inactivation and organics oxidation: both increasing assimilable organic carbon for biofiltration and eliminating trace organic contaminants which may pose a threat to human health. However, ozone can also form disinfection byproducts such as bromate from the …

Organic Carbon Generation Mechanisms in Main and Premise Distribution Systems
Assimilable organic carbon (AOC) is a suspected contributor to growth of microbes, including pathogens, in plumbing systems. Two phases of research were completed to improve knowledge of AOC and other forms of organic carbon in premise plumbing. In the first phase, the AOC Standard Method 9217B was …

Relationship Between Organic Carbon and Opportunistic Pathogens in Simulated Premise Plumbing Systems
… systems via disinfection, control of assimilable organic carbon (AOC), and biologically degradable organic carbon (BDOC). However, much little is known about the effect of AOC on the proliferation of heterotrophic bacteria and pathogens within premise plumbing. This thesis is the first …

Effect of Various Water Chemistry Factors on Legionella Proliferation and the Premise Plumbing Microbiome Composition
… Several water chemistry factors including assimilable organic carbon (AOC) content, granular activated carbon (GAC) biofiltration, plumbing materials, copper concentrations and temperature were investigated using SGWHs. AOC is the carbon available for bacteria growth in drinking water. …

Investigation of biofilms in copper tube corrosion and the survival of <i>Legionella pneumophila</i> on alternative plumbing materials
… in the dissolved oxygen concentration and assimilable organic carbon. Copious amounts of biofilrn were recovered from the pipe surfaces thus it was hypothesised that metabolically active and respiring biofilm bacteria contributed to the creation of aggressive corrosive conditions at the …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
… produces hydroxyl radicals that degrade organic micro-pollutants. However, radicals react non-selectively with natural organic matter (NOM). This research effort quantified the effect of NOM variation on the efficiency of UV/H<sub>2</sub>O<sub>2</sub> contaminant destruction, explored the …
