Info

UV-Peroxide Startup ‣ Geosmin @ startup 10-15 ng/L ‣ UVT 93% to 95% ‣ Trials with low peroxide dose to quench chlorine residual and establish rechlorination dose and response time ‣ Operated only one reactor ‣ Re-optimize when Geosmin levels increase
Summary ‣ AOPs gaining in popularity for drinking water applications; ‣ PAC especially lignite based provide greater Geosmin removal efficiencies if added PRIOR to coagulant addition; ‣ AOPs can be cost effective: ‣ for T&O especially if a component of the AOP such as O 3 is being used for DBP control; ‣ UV is also being used for disinfection; ‣ when considering costs of solids handling.
