  1. aAlgal biomass productivity calculated as dry weight per area of land used by the reactor per unit of time
  2. bAlgal biomass productivity calculated as dry weight per area of growth surface per unit of time
  3. cArea ratio of growth surface area to footprints area of the reactors which calculated based on the parameters of the reactors from the corresponding studies listed above, due to lack of detailed information of some studies, area ratio was given as a conceivable range
