reduction treatment train to reduce nitrogen and phosphorus will consist of water lettuce scrubbers that will remove the majority of the nutrients and settable suspended solids from the water, followed by an algal treatment unit for additional nutrient polishing and reoxygenation. This may be followed by a created wetland to offer additional detention time that may assist in removing organic forms of nitrogen and phosphorus that are typically not easily removed by plants. A simplified flow schematic of the envisioned system follows: North Relief Water Lettuce Algal Created Canal Water Scrubbers Reoxygenation 10 Wetland Unit System Harvested Water Return of Treated Water Lettuce and Algae for """""""'� to the North Relief Compost Production Canal Water Our review of the pilot plant data indicates the NRC MAPS should achieve the following estimated nutrient reductions based on harvested biomass: • TN removal = 8,600 pounds/year • TP removal = 1,500 pounds/year. Pilot plant results indicate the design NRC MAPS flow rate should be around 12 million gallons pumped into the system over a twelve-hour period. The pumping system will be a variable speed system to allow operational flexibility during varying environmental conditions. Project Funding Request, Major Expenses, and Anticipated Matching Funds Funding Request: $250,000 for project construction Major Expenses. Construction costs Anticipated Matching Funds: The County anticipates it will receive over $2,000,000 in matching funds from SJRWMD, FDEP/EPA, and the Florida legislature. All other necessary matching funds will be provided by Indian River County. If you have any questions, please call me at (772) 226-1562. Thank you for your time and attention. Sincerely, W.
