Abstract

Advanced hybrid mathematical model of the Verhulst model and extended Monod model has been developed to predict the microalgae Botryococcus sp. growth in a hollow cylindrical photobioreactor. The hole in the center of the reactor is connected with a source of light. This design is invented to control the light irradiance inside the photobioreactor since light is one of the vital factors for microalgae photosynthesis. With the selected parameter values, the growth of microalgae Botryococcus sp. was estimated by using the hybrid model and the result was validated and showed a good agreement with the experimental data of microalgae Botryococcus sp. growth with a mean absolute percentage error (MAPE) of 19.12%. The growth rate of microalgae Botryococcus sp. in a hollow cylindrical photobioreactor was slightly higher than the growth rate of microalgae Botryococcus sp. in a conventional cylindrical photobioreactor. This proves that the microalgae productivity can be improved by using the hollow cylindrical photobioreactor.
