To fill in this niche and to make the development of ecological biotechnologies more intense in Lithuania, a biofilter with the activated pine-bark charge has been designed at the Department of Environment Protection of Vilnius Gediminas Technical University; besides, complex research on biological air purification processes have been carried out with the help of this biofilter. Using biologically activated pine-bark charge in the developed filter, to carry out biological air purification research and to evaluate the efficiency of the theoretical and practical methods and its application. The fractionated charge of coniferous bark has been used in the special equipment with natural microflora cultivated for air purification from volatile organic compounds; and the potential of the employment of the developed equipment has been fully evaluated after theoretical and experimental researches and mathematical modelling. The experimental researches and their results prove that development and use of biofilters for air purification from volatile organic compounds at various production enterprises of Lithuania is promising. Its implementation is especially promoted by comparatively low capital and operation costs of air purification, high air purification efficiency and strict norms of pollutants emitted into the air set in the European Union.
