The Gwinnett County Department of Public Utilities (GCDPU) decided to purchase an online
total 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 and
suppliers, it was not clear which type of instrument or which brand might work best at this
facility. The GCDPU hired a consulting firm to perform a 1-month evaluation of several of
the most prominent instruments on the market. Water Treatment Research, Inc. (WTR)
contacted four vendors who were willing to supply an instrument for the 1-month
demonstration period at no charge in hopes of having their instrument purchased by the
GCDPU for use at the LFP. After the study was completed, it was clear that many differences
existed between the various instruments. Further, it was clear that some of the key parameters
were not readily apparent prior to the actual study. This paper was written in an effort to
assist other water utilities in selection of the best TOC instrument for their utility. Several key
issues and some major concerns associated with the selection on an online TOC are detailed
in this paper. The GCDPU and WTR are not endorsing any of the instruments tested in favor
of providing a comparison matrix that can be assigned weightings (based on individual
preferences and concerns) to select the best instrument for a given application. Includes table, figures.
