AWWA WQTC64066

The objectives of this slide presentation were to: determine whether there are statistically significant impacts due to water constituents for the treatment of PUFA and other T&O compounds using UV/H₂O₂, generate a predictive model; generate models that predict the log removals of the T&O compounds in each of the treated waters; and, evaluate the hydroxyl radical scavenging potential of the three waters. Bench-scale experiments are outlined, along with collimated beam apparatus and water quality parameters. In summary, The CCD experiment demonstrated that removals of T&O compounds using the AOP UV/H₂O₂ were water-specific, only for IPMP could a single mathematical model be generated at the 1% or 5% significance level to estimate its log reduction for all three of the treated waters selected. While UV photolysis alone may be capable of mitigating the PUFA T&O compounds (not illustrated), efficient mitigation of geosmin, MIB, and the pyrazines would likely require an AOP in agreement with previous experiments.
