Abstract
A closed transparent photobioreactor having a dome and a staged column wherein the dome is used as a growth chamber to provide a large culture volume to land area used and a flow pattern inside the dome allows for the uniform distribution of light energy, thereby negating growth rate inhibiting ‘dark zones’. A pump delivers culture from the bottom of the column to a lower portion of the dome and drives circulation between the two components and an increase in mass in the dome results in a spillover from the top of the dome into the column. Once in the column, algaculture will be aerated at each stage before returning to the dome. The staged column also provides for semi-continuous harvest of algae through the application of froth flotation and various other separation processes.
