Developing a CO₂ bicarbonation absorber for promoting microalgal growth rates with an improved photosynthesis pathway

Abstract

To increase the residence time of CO₂ gas added directly to the raceway pond, a CO₂ bicarbonation absorber was proposed to convert CO₂ gas and Na₂CO₃ to NaHCO₃, which was dissolved easily in the solution and left to promote the biomass growth rate.
