CO2 mass balance in a suspension of algae cultivated in the neutral pH region of the suspension on an open cultivation surface

Abstract The CO 2 mass balance for a suspension of algae cultivated in the region of neutral pH of the suspension on an open cultivation surface with a flowing suspension was assessed. From this balance an analytical expression for the course of free CO 2 dissolved in the suspension along the flow of the suspension is obtained. Relations for the rate of CO 2 decrease in the suspension and the utilization of CO 2 supplied to the cultivation surface are derived.
