Abstract

This thesis describes the production of microalgae under outdoor conditions, for this research was done at pilot scale. Microalgae are an interesting alternative to currently used sources for bulk commodities as food, feed and chemicals. Research activities within the field are shattered; different reactor systems are investigated at different locations while the systems are operated with different species. The shattered activities prevent a consensus to be reached within the scientific community on the reactor system that has the best performance. Selecting the best performing reactor system will bring the algae industry to the next level. In this PhD thesis different reactor designs were compared on a single location while using the same species in all systems. For this purpose the microalgal pilot facility AlgaePARC (Production And Research Centre) was designed and is described within this thesis. Followed by a comparison of the different reactor designs while using for each comparison a different operational strategy. Operational strategies investigated were chemostat operation and turbidostat operation. During chemostat operation a fixed daily dilution rate is applied to the reactor system, biomass concentrations vary as a result of the applied dilution rate and light conditions. During turbidostat operation the biomass concentration within a system is fixed and as a result of the set biomass concentration and light conditions the daily dilution rate varies. Findings from laboratory scale to pilot scale experiments are extrapolated to indicate the potential of microalgae production at a commercial scale. For these extrapolations mathematical models should be used, which require microalgae species specific input parameters. In this thesis input parameters for two industrially relevant microalgae species were obtained and reported. Finally a techno-economic evaluation was developed to indicate the potential of microalgae as a bulk commodity and to pinpoint focal points for future research.
