Abstract: Nutrient pollution and harmful algal blooms cost the Nation an estimated $1B each year. The U.S. Army Engineer Research and Development Center (ERDC) began research on the Harmful Algal Bloom Interception, Treatment, and Transformation System (HABITATS) project to develop scalable solutions for managing large Harmful Algal Blooms (HABs), with the objective to develop a rapidly deployable system for mitigating large HABs at various design scales. The first year’s progress includes: (1) development and deployment of an interception technology that efficiently collects algae at the water surface, (2) validation of high through-put treatment using dissolved air flotation (DAF) technology to clarify algae-laden water, (3) oxidation of the DAF effluent using ozonation for removing microcystin and other potential cyanotoxins, (4) successful permitting with the Florida Department of Environmental Protection for discharging the treated water back to a surface water body at the demonstration site, (5) demonstration of rapid concentration of algae from a natural water source, (6) transformation of concentrated algae from the study site into biocrude oil at bench scale, and (7) development of a scalability analysis model to establish baseline estimates for full scale performance and cost.
