New Tools for Optimizing UV Disinfection Life Cycle Costs

摘要

A new software tool named UVCAT has been developed through a New York State Energy Research andrndevelopment Authority (NYSERDA) project entitled "Optimization of UV Disinfection". The software providesrnsimulations of UV system operation and performance as a function of time. Inputs to the software include water andrnflow data over time, UV validation data describing dose delivery and monitoring, lamp aging and fouling curves,rnUV system configuration data, data on dose pacing, and UV system O&M cost data. Outputs from the softwarerninclude on/off status, power level, and lamp life for each bank in the UV system, power consumption for the UVrnsystem under actual and ideal dose pacing scenarios, daily and accumulated power costs, and offspec performance.rnAll this information is provided as a function of time and can be used to assess if the UV system proposed for arngiven application is under or over sized and providing efficient dose pacing. The software also provides O&M andrnlife cycle costs for the system under consideration. UVCAT provides a more accurate assessment of O&M and liferncycle costs compared to standard approaches used by the industry because it better accounts for the true performancernof the UV system. The software also provides novel approaches for sizing and operating UV systems that shouldrnoptimize capital and O&M costs and provide better selection of UV systems for a given UV application. Thernsoftware is currently being revised to provide a more complete estimate of offspec performance and its impact onrnpublic health protection. The software will be finalized Summer 2005 and provided to the water and wastewaterrnindustry for use through NYSERDA and AwwaRF.
