Algal Biofuels Feedstock Demonstration


Demonstration of Algae as a Feedstock for Biofuels: Phase 1

In 2009 a test-bed algal turf scrubber (ATS) was installed along the Spring Creek in Springdale, AR to facilitate nutrient removal from the stream and generate algal biomass for biofuel production.  The ATS system yielded high biomass production rates, averaging 26 g m-2 d-1 over the course of the nine month operating period.  Nutrient removal was also high, with total phosphorus removal averaging 48% across the ATS system.   The biomass generated from this system was used by the University of Arkansas Department of Chemical Engineering for conversion to biodiesel and butanol.

This project was done in partnership with The Smithsonian Institution and The Lewis Foundation.

Demonstration of Algae as a Feedstock for Biofuels: Phase 2

Phase 2 of the algal feedstock program involved the construction of a pilot-scale algal growth bed (AGB) system at the Paul R. Noland Wastewater Treatment Plant in Fayetteville.  This system is three times the size of the test-bed algal turf scrubber constructed in Springdale, and is in its second year of operation.  The AGB removes nutrients from the wastewater treatment plant effluent, and provides biomass for biofuel conversion projects at the University of Arkansas.

This project was done in partnership with R. Noland Wastewater Treatment Plant and CH2M Hill.
