[Biological methods of air purification (review of the literature)]

Biological methods of air purification are reviewed, which can be applied to deep air purification of complex multicomponent mixtures from harmful, toxic and odorous substances at room temperature and atmospheric pressure. Microbiological and technological aspects of the problem are discussed. Operation characteristics of biofilters, bioscrubbers and trickle bed bioreactors are compared. Prospects of air biopurification are considered.
