Abstract
A method for the purification and biodeodorizing of a gas effluent charged with pollutant matter is provided. The method includes the steps of passing the gas effluent through a bed of inert granular material used as a support for a biomass. The biomass includes bacteria, majority of which are autotrophic bacteria. Preferably the bacteria are in a form designed to degrade the pollutant material. The method includes the step of sprinkling the bed with a sprinkling liquid and recovering purified biodeodorized gas effluent. Preferably, nutrient elements for the biomass are supplied entirely by the sprinkling liquid, the gas effluent or a mixture thereof.
