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