This study aims to investigate the effect of column diameter (D), height/diameter (H/D) ratio, and gas flow rate on microalgae culturing, Haematococcus pluvialis. Bubble column reactors with various D and H/D ratio were tested to assess the hydrodynamic properties and biomass production performance. Then, H. pluvialis was cultured under outdoor autotrophic conditions using industrial flue gas. Reactor volume increased to 354% with minimized biomass loss by optimizing the reactor module. Compared to the control, developed module showed biomass and astaxanthin productivity of 0.052 versus 0.053 g/L/day, and 1.48 versus 1.47 mg/L/day, respectively. Consequently, biomass productivity was retained with increased reactor scale, and the result is appropriate for the scale up of overall microalgae cultivation process.
