【 摘 要 】

Microalgae ability to utilise CO2higher compared to terrestrial plant making it suitable for biomass production and as CO2utiliser. This could be one of many ways to preserve a safer and healthier environment with less air pollutant. For study purposes, CO2usually transported to microalgae culture broth with the aid of membrane technology to prevent formation of large bubble and to accelerate the carbonation of microalgal media. However, membrane susceptible to accumulation of CO2, which can cause extreme acidic to microalgal media. This prevents microalgae to assimilate CO2. Thus, this study proposes correlations to prevent the extreme acidic: which represents the relationship of: (1) CO2inlet and accumulation, (2) CO2inlet and CO2at the membrane-liquid interphase and (3) CO2inlet and CO2 solubility in the media. The correlations were successfully validated with a deviation of less than 20% compared to the theoretical value.
