The City of Tempe, Arizona is planning to expand their Johnny G. Martinez Water Treatment
Plant (JGMWTP) from an existing capacity of 50 mgd to 80 mgd. As part of this expansion, process
upgrades are also being considered to improve finished water quality. Key water quality goals to
be addressed in this upgrade/expansion are the removal of chlorinated disinfection byproduct (DBP)
precursors, better control of taste and odor, and increased pathogen inactivation. Existing
processes at JGMWTP include conventional treatment with anthracite/sand filters and
powdered activated carbon to control T&O and also to remove organic carbon. A pilot study was
conducted to evaluate granular activated carbon (GAC) as a potential replacement of the existing anthracite media. Goals
of this study included evaluating the production and water quality performance of the GAC
filters, and to evaluate DBP precursor and taste and odor (T&O) control. Based on the results of this study, GAC
filtration media was recommended for the expanded JGMWTP. Includes table, figures.
