ABSTRACT:
A method and apparatus for removing select gas contaminants is disclosed. The apparatus is a bioreactor having a chamber for containing liquid and a liquid positioned therein, the liquid forming a column having a top and a bottom surface defining a height. The bioreactor further has a gas dispersal unit positioned in the column and a selected biomass suspended in the liquid, where the biomass is selected to metabolize the gas contaminant requiring degradation. The method includes feeding a select gas contaminant having a low Henry's coefficient into the gas dispersal unit to produce a stream of bubbles containing the gas contaminants, where the gas contaminant is a food source for said biomass, and allowing the stream of bubbles to sparge through and exit the top of said column.
