AWWA WQTC71609

The Seymour-Capilano Filtration Plant is Metro Vancouver's first direct filtration plant and willbe the largest operational ultraviolet light system for the disinfection of drinking water followingstart-up of the facility in late 2009. Over the first six months of 2009, various full-scale tests aswell as pilot-scale and laboratory evaluations were conducted to prepare for on-site biodosimetrytesting, which has presented many unique challenges, since this facility was not designed for UVsystem validation. The data from the UV system validation conducted using the 2003 draft ofthe UV Disinfection Guidance Manual was reevaluated in accordance with the final version ofthe manual to determine the energy savings achieved by updating the control philosophy of thesystem. The potential energy savings associated with additional on-site biodosimetry testing wasalso evaluated using performance models generated from a recent validation of a similar UVvessel with an alternative UV-sensitive challenge microorganism, T1 bacteriophage. Energyconsumption and present worth evaluations were conducted to determine which options had thegreatest potential to minimize the cost and optimize the operating efficiency of the UV system. Includes 2 references, tables, figures.
