CO2, which is one of the essential nutrinets for microalgae, takes in charge of a large portion in the biomass production cost. Thus, accurate calculation of CO2 concnetration in microalgal reactors is important to develop optimal CO2 supplement strategy which maximizes algal growth rate while minimizing CO2 leakage. However, conventional transfer models for CO2 concentration estimation are inaccurate as they underestimate CO2 mass transfer rate. Therefore, estimated CO2 concentration is typically lower than measured concentration. In this research, biological enhancement, which is defined as the enhancement of mass transfer in the presence of the biological micro-organism, is incorporated into the conventional CO2 transfer model to estimate accurate CO2 mass transfer rate. By comparison with the conventional model results and measured data, impact of biological enhancement on CO2 supplement strategy is evaluated. |
