Process

The bioscrubbing process eliminates odours found in piped gaseous
effluents.

The process is based on a two-stage treatment: transfer of the odorant
molecules via a washing phase in a gas-liquid contactor followed by
biodegradation of the transferred compounds in an activated sludge basin.
This biological regeneration enables the washing solution to be used
in a closed circuit.
By separating the two stages in two distinct reactors,
each process can be optimized.
