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