Abstract: Aspects of the invention are directed to a system and method of sparging an algae cultivation container. The method may include controlling at least one first sparger to distribute a first fluid into the container at a first operating flow rate; and controlling at least one second sparger to distribute a second fluid into the container at a second operating flow rate. The first operating flow rate may be adapted to allow mixing the algae in the cultivation container, and the second operating flow rate may be adapted to allow assimilation of materials in a liquid in the cultivation container.
