This powerpoint presentation begins by providing background information on Tampa Bay Water and the Lithia Water Treatment Plant in Hillsborough County, Florida. The presentation presents a study on treatment alternatives for H2S removal while meeting water quality (WQ) standards. Parameters of greatest concern include: H2S: < 0.1 mg/L; and, turbidity: < 1.0 NTU. The study also evaluated treatment alternatives that consistently met the above criteria. Process chemistry is presented, along with procedures concerning pilot plant configurations, experimental plan - membranes, bench tests: H2S removal by chlorine; Schematic: Cl2-oxidation - UF; Schematic: Bio-oxidation - UF; Conclusions related to treated water quality and membrane cleaning interval; Integration of Membrane Alternatives into Existing Treatment Process; and, Criteria for Membrane Alternative Rankings. Ranking Results were: Biological Oxidation followed by UF; Chlorine Oxidation followed UF; and, Ozone followed by BAC.
