AWWA ACE70623

This powerpoint presentation begins by providing a brief overview of the city of St. Cloud, Florida, and a regulatory compliance project for the U.S. Environmental Protection Agency (USEPA) Stage I Disinfection Byproducts (DBPs) maximum contaminant limits (MCLs),color and odor MCL violations, improve taste and odor, meet growth demands (9MGD), and maintenance of the city's old facilities. Magnetic ion exchange(MIEX®) was selected as theprimary treatmentmechanism for removal of dissolved organic carbon(DOC),color, andBi-sulfide (HS-). Design objectives included the following: treat groundwater for DOC, color, and H₂S removal; remove remaining H₂S with pH adjustment and aeration; gravity flow through entire plant; maintain chlorine as disinfectant, reduce demand; design for operational flexibility; incorporate facility expansion from 9 to 12 MGD; and, utilize concrete construction. Topics presented include: water quality requirements; design parameters; process flow schematic; gravity flow and low profiledesign concept; design challenges; supervisory control and data acquisition (SCADA) and security; visual result; plant performance results; and, cost summary. Includes table, figures.
