Abstract: | Hydrogen sulphide is one of the commonest odours emitted by chemical plants. To remove the hydrogen sulphide biologically, a three phase fluidised bed bioreactor was used in which Thiobacillus sp.IW was immobilised on activated carbon. The optimum operating conditions of the bioreactor were 30 degrees C, pH7, aspect ratio (L/D) = 1 and at these conditions, the system removed over 94% of the hydrogen sulphide in the concentration range of 100-200 ppm and flow rate of 1.0-2.0 litre min(-1). From the upset and recovery test, the system proved stable within the moderate inlet concentration changes investigated. |
