Advantages of Photobioreactors
Cultivation of algae is in controlled circumstances, hence potential for much higher productivity
Large surface-to-volume ratio. PBRs offer maximum efficiency in using light and therefore greatly improve productivity. Typically the culture density of algae produced is 10 to 20 times greater than bag culture in which algaeculture is done in bags - and can be even greater.
Better control of gas transfer.
Reduction in evaporation of growth medium.
More uniform temperature.
Better protection from outside contamination.
Space saving - Can be mounted vertically, horizontally or at an angle, indoors or outdoors.
Reduced Fouling - Recently available tube self cleaning mechanisms can dramatically reduce fouling.
