Model Development and Light Effect on a Rotating Algal Biofilm

Résumé

The idea relying on attached culture for microalgae production has attracted manyinterest these past years due to their energy efficiency and low water usage. Microalgae cangrow and attach to the surface of an appropriate material to form a biofilm. In this paper, arotating algal biofilm (RAB) model is introduced. It is based on the Han model. How lightaffects the growth and productivity of microalgae and thus the formed biofilm will be discussedthrough model development, more importantly, it will be seen that taking into considerationlight dilution factor can increase productivity. The benefit of the system is assessed when theconveyer velocity is fast enough. Simulation show an optimal folding of the conveyer. Actualproductivities for moderate velocities are assessed and compared to these extreme cases.
