Develop and demonstrate a scalable capability to remove algae and nutrients from large water bodies, and develop resource recovery methods that enable efficient management of the resulting biomass.
A rapidly deployable system for mitigating large harmful algal blooms in an economically viable and sustainable manner.
- Develop deployable system for intercepting algae upstream of a spillway.
- Demonstrate clarification and dewatering processes that efficiently separate algae from water and concentrate the algae to > 15% concentration.
- Destroy any microcystin in the clarified water and discharge to a nearby surface water body.
- Generate biocrude oil from natural algae using hydrothermal liquefaction and confirm hydrothermal destruction of microcystin toxin in transformed biosolids (at bench scale).
Pending continued funding through the ERDC Aquatic Nuisance Species Research program, tasks for 2020 shall include:
- Perform an extended pilot scale HABITATS demonstration, to include a pilot scale hydrothermal liquefaction for management of algae waste on-site.
- Develop shipboard capability for intercepting algae out on the open water.
