Abstract
Yearly almost 15 thousand tons of volatile organic compounds (VOCs) are being emitted in Lithuania by various industries. To reduce
these releases into the air biofiltration, using particular cultures of microorganisms, is one of the most perspective air treatment method.
The possibility to implement biofilter packed with reed charge reducing these amounts and cleaning VOCs and odors is being assessed in
the article. It was analysed removal efficiency of biofilter packed with reed charge, which measured porosity was equal to 80%. The
efficiency of biofilter was measured treating formaldehyde. The results of experiment showed, that the highest overall removal efficiency
E=91.68% treating formaldehyde polluted air stream up to 20 mg/m3
using the upright reed charge decomposition. Therefore, the filter
efficiency was tested depending on the number of its charge layers height and on different injected air stream rate.
Keywords: biofilter; biofiltration; volatile organic compounds; formaldehyde; common reed.
