Abstract
As
population increases, so does the demand for water resources and sustainable
fuel. Promising new research is used to explore merging wastewater nutrient
removal and the development of renewable fuels such as microalgae biofuels.
Advances have been made in microalgae biofuels to not only yield a renewable
fuel but algae grown can be used for a variety of uses including: wastewater
treatment, pharmaceutical applications, and as a fertilizer. The purpose of
this study is to increase our understanding of how algae interact in wastewater
including phosphate nutrient removal and biomass growth. Chlorella vulgaris was grown in Kenosha
County wastewater to determine the step in the wastewater treatment process
that is most optimal for algae growth and water treatment. Conditions such as
temperature, light, air and CO2 were controlled in an incubator set
up at Carthage College. The algae was grown in waste activated sludge centrate,
dewatered centrate and final treated wastewater. Phosphate removal was recorded
and biomass of the algae was determined throughout the experiment. Further
experiments can be done to explore these results along with investigating
algae’s interaction with wastewater sources, optimal conditions for growth, and
biodiesel applications.
