Integrated system for the conversion of solar energy with sewage grown microalgae. Final report, October 1, 1976-September 30, 1977
An integrated system for wastewater treatment and microalgae biomass production for conversion to fuels is proposed. Progress in the development of low cast biomass production system using sewage as a source of nutrients and water is reported. The theory of species control through selective biomass recycle is refined and demonstrated in laboratory experiments. The outdoor pond system was further developed and microstrainer effectiveness tested in multivariant experiments. The outdoor pond operations consisted of a series of experiments to test the effects of detention time, recycling and mixing on algae culture harvestability, and productivity. Batch and continuous secondary growth ponds were operated to result in low ammonia pond effluents, after algae settling or microstraining. These effluents were used to grow nitrogen-fixing blue-green algae. The 0.25 hectare pond was operated to determine whether small scale experimental results can be extrapolated.
