Harmful Algal Bloom Interception, Treatment, and Transformation System, HABITATS: Pilot Research Study Phase I Summer 2019
Abstract
Nutrient pollution and harmful algal blooms cost the Nation an estimated $1B each year. The U.S. Army Engineer Research and De-velopment Center (ERDC) began research in the Harmful Algal Bloom Interception, Treatment, and Transformation System (HABI-TATS) 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 years progress includes: (1) development and deploy-ment of an interception technology that efficiently collects algae at the water surface; (2) validation of high throughput 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) devel-opment of a scalability analysis model to establish baseline estimates for full scale performance and cost.
