TAYLOR CREEK ALGAL TURF SCRUBBER® NUTRIENT RECOVERY FACILITY for PHOSPHORUS and NITROGEN CONTROL in OKEECHOBEE, FLORIDA
Mark J. Zivojnovich, E. Allen Stewart, P.E., Robinson Bazurto, and Kimberleigh Dinkins HydroMentia, Inc. Ocala, FL
The Algal Turf Scrubber® (ATS™) has been employed as a structural Best Management Practice (BMP) at Taylor Creek in the Lake Okeechobee Watershed, Florida. The project augments activities of the Lake Okeechobee Protection Program, and is expected to reduce phosphorus and nitrogen pollutant loading to the lake by 4,000 and 17,087 pounds per year, respectively based water quality data for the period 1989-2005,. The facility has a daily flow of 15 million gallons with a process area of approximately 3.6 acres.
The Algal Turf Scrubber® is a managed aquatic plant system, which utilizes cultured algae to remove pollutants from impaired waters. Targeted nutrients are removed from source water through direct plant uptake, chemical filtration and precipitation, and are managed through
routine biomass recovery. introduced in pulsed flows

The system began operation in January 2007 and has been funded by the Florida Department of Agriculture and Consumer Services (FDACS) in cooperation with the South Florida Water Management District (SFWMD). ATS™ design and first quarter nutrient load reduction results will be presented.
