Comparative Evaluation Of Floating Treatment Wetlands For Nutrient Removal And Algal Toxin Control In Wet Detention Ponds

Abstract

Stormwater nutrient removal is a major contributor to loadings in natural waterbodies, and any system not protected by the state or less than 10 acres operates without water quality indefinitely. The permits do not require monitoring by private owners, but the effects are considered to be a contributor to the eutrophication of water bodies across the world. Biomanipulation (biological mitigation) with the emerging technology called the floating treatment wetland (FTW) can be used to remove nutrients, while preserving aquatic ecosystem structures with native aquatic plants. However, logistical concerns arise if the mitigation does not achieve an enhanced removal or even negative removals. Two field studies conducted in Orlando, Florida, are used to investigate nitrogen and phosphorus removals when FTWs are deployed and compared to the control counterparts without the FTWs. The first evaluation was performed in Pond 4M at the University of Central Florida (UCF). The data were used to create an estimated 12% nutrient removal credit presented in a report to the Florida Department of Transportation (FDOT).
