AIR PURIFICATION SYSTEM AND METHOD WITH BIOLOGICAL TREATMENT OF A SCRUBBER LIQUID

摘要

An air purification system for purifying polluted air includes a scrubber in which a pollutant in the polluted air is transferred to a scrubber liquid. A biological treatment unit includes at least one substantially flat substrate to support a microorganism population to remove the transferred pollutant from the scrubber liquid when the scrubber liquid with the transferred pollutant is distributed on the substrate. A plane of the substrate is substantially parallel to a direction of flow of the air from the scrubber.
