Gas scrubbing systems absorb gaseous pollutants in liquids as water, sometimes with added chemicals
Wet scrubbers can be manufactured as single or multistage unit, round, angular, upright or horizontal for indoor or outdoor construction.
The nutrient liquid ensures optimum biological process conditions for the microorganisms, which settle to the surface of the filter bed’s carrier material. The microorganisms convert the pollutants into CO₂ and water. The nutrient liquid re-enters the filter by spraying nozzles due to a circulation system.
