PENGARUH LAJU ALIR INJEKSI GAS EMISI PADA FOTOBIOREAKTOR TERHADAP PENYERAPAN CO 2 OLEH CHLORELLA SP

Abstract

Carbon dioxide (CO2 )gases that dominated by anthropogenic activities cause
various negative impacts on the environment and surroundings due to increasing its
concentrations in the atmosphere. There are some techniques to mitigate against
the increase of CO
2 which one is the utilization of phytoplankton cultured in a photo
bioreactor (FBR) as an natural absorber. In this study, the influence of input gas CO2
flowrate on Chlorella sp at multiple tubular air lift photobioractor (FBR) was measured
in milk factory field. The CO2 flowrate continuesly was controled by 2 l/min and 1.5 l/m
during experiment. Result showed that Chlorella sp. have a good adapted ability of CO2
10-15% vol industrial emition. The experiment result stated that reactor capability at
FBR-1 was lower than FBR-2. The reactor capability at FBR-1 and FBR 2 were 0,78 ±
0,25 and 0,92 ± 0,36 g/l. media/day.
