Abstract Details

2012, Master of Science (MS), Ohio University, Mechanical Engineering (Engineering and Technology).
One of the major contributors to high processing costs of microalgae for biofuel is the harvesting and dewatering of the microalgae, which can account for 20-30% of the total cost. Microalgae can potentially become a more economical feedstock for biofuel if the capital and operational costs of the harvesting/dewatering step are reduced by using a novel microscreen and capillary belt system. By modifying the well section of the Algaeventure Systems prototype harvester, the flow rate of live Scenedesmus dimorphus algae through the harvester system was increased by an average of 166.8% and the power consumption per unit mass was decreased by an average of 51.4%. A modified testing rig was also constructed to eliminate a belt tracking and media spill-over issue through development of an autonomous belt tracking system. Chlorella powder and tomato juice were tested under the same conditions as the live algae to determine a suitable surrogate material to live algae.
