N2 - Flue gases from sulfuric acid industry mainly contain of Sulfur Dioxide (SO 2) gas. One relatively new technology which might efficient to remove SO 2 emission is Biological Flue Gas Desulphurisation. To investigate potential of Bio-FGD application in Sulfuric Acid Industry, research was conducted. Research was conducted in Bench-scale Bio-FGD consists of several unit operation which are absorption tank (R 1), Sulfate reduction bioreactor (R 2), Stripper (STR), H 2 S gas Scrubber (R 3) and regeneration bioreactor (R4). Performance 2 evaluation to optimize Bio-FGD was conducted by preliminary simulation of operational variable. Optimum condition in R 1 occur when EBRT = 1 minute and mass loading 3.50 g.m• 3.hour• 1. Optimum condition in R 2 occur when HRT = 3 hour, mass loading = 84 g.m• 3.hour• 1 and nutrient flow rate = 10% of reactor volume/day. Optimum conditions in STR occur when air flow rate to STR is 40% of reactor volume/minute. Optimum condition in R 3 occur when mass loading = 0.155 g.m• 3.hour• 1. Optimum condition in R 4 occur when HRT = 4 hour, mass loading = 13 g.m• 3.hour• 1, air flow rate = 22% of reactor volume/hour and nutrient flow rate= 10% of reactor volume/day
