Full Description

The Eagle Mountain Water Treatment Plant (EMWTP) in Fort Worth, Texas, wasbrought on line in 1992. Now, only six years later, the EMWTP requires expansionto a capacity of 60 million gallons per day because of the rapid growth in theFort Worth service area. The expansion of the ozonation facilities proved to bemore complicated than just adding additional generation equipment and contactors.Advances in ozonation technology over the past six years required the authors toreconsider such basic parameters as feed gas, cooling water, and controlstrategy. This paper documents the process of system evaluation and the design ofthe ozonation facilities at the EMWTP, and brings to light issues other designersshould consider in future ozonation facility expansions. Among these factors areadvances in dielectric technology, allowing higher ozone concentration at lowerspecific energy; changing feed gas from air to oxygen; incorporating actual plantoperational history using ozone; and bidding and procurement alternatives. Theozone facility expansion increased the production capacity from 560 pounds perday to 2600 pounds per day, and converted the feed gas from air to oxygen. Includes 2 references, tables.
