EVENT DETAIL

The City of Tampa’s (City) Water Department owns and operates the 120-mgd David L. Tippin Water Treatment Facility (DLTWTF) located in Tampa, Florida. The Hillsborough River, DLTWTF’s primary source of water, experiences high seasonal variability, in particular raw water total organic carbon (TOC) ranging from 3 to 30 mg/L, and it is challenging to maintain high-quality finished water under the wide range of influent water quality conditions throughout the year. Given the DLTWTF’s existing water quality challenges, need for expansion, and extensive chemical use and solids generation, a detailed alternatives analysis of treatment alternatives was completed as part of master planning efforts. A pilot study was recently completed demonstrating a new suspended ion exchange (SIX) process, which is the first of its kind the United States, as a promising new technology to help overcome the City’s challenges.
