Abstract

Bioscrubbers involves the physical separation of Volatile Organic Compounds and its biological treatment. The waste gas is purified in the absorber called gas liquid contactor, in which the transformation of pollutants takes place from gas to liquid phase. The H2S removal efficiency is higher in the bioscrubber. There are several types of bioscrubbers are discussed here under. Principles involved in the bio scrubbing process are bio transformation and bio-oxidation of pollutants present in air. It contains absorption column, gas liquid phase and liquid contactor. Operations are based on the few parameters like liquid flow rate, gas velocity, filter material, microbes and moisture content. It also has its specific view on the environmental benefits like no usage of chemicals, which does not cause any harm to environment. Advantages and disadvantages of these bioscrubbers and its drawback on removal of gases like H2S, NH3 and VOC are discussed.
