In anticipation of the proposed Long-Term 2 Enhanced Surface Water Treatment Rule(LT2ESWTR) and disinfection byproducts (DBP) regulations, the City of Albany (City), NewYork is implementing a water quality enhancement program at its uncovered finished waterstorage facility, Loudonville Reservoir. The first phase of the water quality enhancementprogram was the construction of an ultraviolet (UV) treatment facility. Construction of the UVtreatment facility was completed in the Spring of 2003 with full-scale operation beginning onApril 1, 2003. This UV treatment facility represents the largest such facility for drinking waterin New York State, and one of the largest in the United States.The New York State Energy Research and Development Authority (NYSERDA), a publicbenefit corporation that administers the New York Energy $martSM program, made $1.2 million incost-shared grants available for projects that are focused on innovative, energy-efficient methodsto treat water and wastewater. A NYSERDA research grant to validate and optimize the City ofAlbany's UV treatment facility was competitively selected for co-funding under the program.As part of the NYSERDA co-funded study, Malcolm Pirnie personnel will work with Citypersonnel to monitor and record system start-up and operating data. The data will be used toestablish a maintenance program for the field equipment used to control the system (e.g., flowmeters, on-line transmittance monitors, intensity sensors) to maintain the energy efficiency of thesystem. In addition, on-site validation will be used to optimize the dose set points and tomaximize the flexibility and power optimization for the system. A sensitivity analysis of thevarious aspects of the system (e.g., lamp age, fouling, equipment drift) will be conducted toestimate the effect on energy consumption and assist in the establishment of appropriate designcriteria (e.g., lamp aging/fouling factor) for future UV treatment projects.To date, there are very few large-scale UV treatment installations within the United States andmuch of the industry's knowledge is based on academic research and "paper studies". Given thesize, unique application, use of on-site validation, and detailed assessment of the energy aspectsof the system, the lessons learned through the City of Albany's UV treatment facility project willprovide a significant contribution to other communities that are considering the integration ofUV treatment into their treatment strategy. This paper reviews the lessons learned during thedesign, construction, start-up of the UV facility and describes the future of the NYSERDAresearch study. Includes 5 references, tables, figures.
