Abstract
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.
Claims20
An air purification system for purifying polluted air, the system comprising:
- a scrubber in which a pollutant in the polluted air is transferred to a scrubber liquid;
- and
- a biological treatment unit comprising 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 said at least one substrate, a plane of said at least one substrate being substantially parallel to a direction of flow of the air from the scrubber.
An air purification method for purifying polluted air, the method comprising:
- exposing a scrubber liquid to the polluted air in a scrubber to enable a pollutant in the polluted air to transfer to the scrubber liquid;
- distributing the scrubber liquid with the transferred pollutant on a substantially flat substrate of a biological treatment unit to enable a microorganism population that is supported by the substrate to remove the pollutant from the scrubber liquid;
- and
- causing air from the scrubber to flow across a surface of the substrate in a direction that is substantially parallel to the surface.
A biological treatment unit for an air purification system, the unit comprising at least one substantially flat substrate to support a microorganism population onto which a scrubber liquid may be distributed after a pollutant is transferred from polluted air to the scrubber liquid in a scrubber, the microorganism population to remove the pollutant from a scrubber liquid, a plane of the substrate being substantially parallel to a direction of flow of the air from the scrubber.
