Enhancing CO2 mass transfer in algal raceway ponds through wave generation
… of microalgae is currently mostly done using raceway ponds. These ponds however suffer from low algal productivities compared to closed photobioreactors, in part due to inadequate CO2 mass transfer into the culture. A previous study at the University of Cape Town explored a method to improve …

Enhancing CO2 mass transfer in large scale algal raceway ponds through wave generation
The commercial growth of algae in raceway ponds is limited by the availability of carbon, supplied as carbon dioxide (CO2), resulting in a linear growth rate, also described as biomass productivity, determined by the mass transfer rate. This reduces the specific growth rate of the system, as the …

Carbon dioxide mass transfer within algal raceway ponds and the potential for improvement using slopes to create wave
… as capture and cycling of CO₂. The fast micro-algal growth rates and ability to grow on agriculturally poor land and in waste water means that bio-production using algae has many advantages over traditional agricultural processes for certain applications. The raceway pond is the most common …

Heat Transfer and Flow in Solar Energy and Bioenergy Systems
… Solar Power (CSP) plants and open-channel algal culture raceways for biofuel production. The first part of this dissertation is the discussion about mathematical modeling, numerical simulation and experimental investigation of solar TES system. First of all, in order to accurately and …

Growth Media and Lipid Determination Comparison of High Rate Algae Ponds
… Alexander Nicolai</p> <p>The feasibility of algal biofuel production relies on the use of a non-potable water source. Municipal wastewater is nutrient-rich and a cost effective option as a growth media in algae ponds. However, this resource may be too valuable for algal biomass production, as …

Towards bioengineered ecosystems: Three studies in invasion biology
… contamination of open culture systems such as algal raceway ponds. Biological invasion theory attempts to predict what makes a community vulnerable to invasion, what characteristics make an invader successful, and what consequences following invasion might arise. In this thesis, a review of …
