AWWA WQTC60698

The Gwinnett County Department of Public Utilities (GCDPU) decided to purchase an onlinetotal organic carbon (TOC) analyzer to help improve process control at the Lanier Filter Plant(LFP) in Buford, Georgia. Due to the variety of available measurement technologies andsuppliers, it was not clear which type of instrument or which brand might work best at thisfacility. The GCDPU hired a consulting firm to perform a 1-month evaluation of several ofthe most prominent instruments on the market. Water Treatment Research, Inc. (WTR)contacted four vendors who were willing to supply an instrument for the 1-monthdemonstration period at no charge in hopes of having their instrument purchased by theGCDPU for use at the LFP. After the study was completed, it was clear that many differencesexisted between the various instruments. Further, it was clear that some of the key parameterswere not readily apparent prior to the actual study. This paper was written in an effort toassist other water utilities in selection of the best TOC instrument for their utility. Several keyissues and some major concerns associated with the selection on an online TOC are detailedin this paper. The GCDPU and WTR are not endorsing any of the instruments tested in favorof providing a comparison matrix that can be assigned weightings (based on individualpreferences and concerns) to select the best instrument for a given application. Includes table, figures.
