HABITATS

The Harmful Algal Bloom Interception, Treatment, and Transformation System (HABITATS) demonstrates a scalable capability to remove algae and nutrients from large bodies of water, and develop a resource recovery method that enables efficient management of the resulting biomass. The Blue-algae that has been concentrated from lake water using a dissolved air flotation process falls from the treatment unit into a collection tank. search > ERDC HABITATS | Contact: ERDCinfo@usace.army.mil

Research Objective: Performing research to develop and demonstrate a scalable capability to remove algae, algae-entrained nutrients and potential algal toxins from large bodies of water; and develop resource recovery methods that enable efficient management of the resulting biomass while destroying any potential toxins.

Vision: A rapidly deployable system for mitigating large harmful algal blooms in an economically viable and sustainable manner.

Approach:

INTERCEPTION TREATMENT    TRANSFORMATION

 

2020 Pilot Scale Demonstration Milestones:

  • Optimize and validate deployable on-shore system for intercepting algae upstream of a spillway.
  • Develop, optimize and validate a mobile shipboard system for removing algae on the open water.
  • Deploy a pilot scale system that generates biocrude oil from natural algae using hydrothermal liquefaction and confirm hydrothermal destruction of microcystin toxin in transformed biosolids (at bench scale).
  • Improve fuel production yields through incorporation of organic coagulants for water clarification and a high throughput press for biomass dewatering.

2020 Scope:

  • Perform on-shore HABITATS demonstration in Florida (July/August 2020)
  • Perform mobile shipboard HABITATS demonstration in New York (August/September 2020)
