As the small barge floats around Lake Jesup –– one of Central Florida’s largest and most polluted water bodies –– it drags along a large hose that sucks in thousands of gallons of the murky water tinted green and brown from algae and other pollutants.
The water is then siphoned into a holding tank where a filtration system removes the algae, phosphorous and nitrogen. Minutes later, the clearer water is poured back into the east Seminole County lake that sits between Sanford and Oviedo.
Meanwhile, the leftover gooey algal biomass is loaded into trucks and driven to the county’s Yankee Lake Wastewater Treatment Plant.
Called an algae harvesting unit, the system is a pilot project that kicked off on Lake Jesup this month by the St. Johns River Water Management District and will continue through Spring 2022.
Lake Jesup in Seminole County is set to get help from an algae harvester but residents say the effort will do little to clean the water.
