Method and apparatus for air treatment

摘要

A ventilation system has a water treatment section (54) which applies droplets of water (58) to contaminated air. The water is then removed by an entrainment separator (62). The air is passed over a series of UV lamps (70) which generate ozone sufficiently fast to strip off the layer of ozone formed on the UV tubes. Photolysis, ozonolysis and oxidation all reduce the level of organic contaminants in the air stream. The air then passes over a second UV source which decomposes any remaining ozone.
