Conversion of NaHCO3 to Na2CO3 with a growth of Arthrospira platensis cells in 660?m2 raceway ponds with a CO2 bicarbonation absorber
Summary The weight ratio of Na2CO3/NaHCO3 was investigated in order to improve microalgal productivity in large‐scale industrial operations by converting NaHCO3 to Na2CO3 with a growth of Arthrospira platensis cells in 660?m2 raceway ponds. Two microalgal cultivation systems with a NaHCO3 by‐product (SPBP) and a CO2 bicarbonation absorber (CBAP) were firstly thoroughly introduced. There was a 13.3% decrease in the initial weight ratio of Na2CO3/NaHCO3 resulting in a 25.3% increase in the biomass growth rate with CBAP, compared to that of SPBP. Increased sunlight intensity, solution temperature and pH all resulted in both a higher absorbance and release, thereby increasing the weight ratio of Na2CO3/NaHCO3 during the growth of A.?platensis. The biomass growth rate was peaked at 39.9?g?m?2?day?1 when the weight ratio of Na2CO3/NaHCO3 was 3.7. Correspondingly, the cell pigments (chlorophyll a and carotenoid) and trichome size (helix pitch and trichome length) reached to a maximum state of 8.47?mg?l?1, 762?μg?l?1, 57 and 613?μm under the CBAP system.
