Examination of the biofiltration of air polluted with methyl isobutyl ketone

Biofiltration used for reduction of pollutant atmospheric emissions is difficult to design and hence experimental information about the course of fragmentary processes is still required. Researchers' efforts are thus oriented on the extension of knowledge about them as well as on attempts to generalise the phenomenon's description. This paper presents results of the measurement of biofiltration of the air polluted with methyl isobutyl ketone. Examinations were carried out in a biofilter column, 190 mm in diameter and 1400 mm high. Biofiltration bed, with a volume of 31.5 dm3, was composed of pine bark and compost from urban-industrial waste. Methyl isobutyl ketone concentrations were within the range of 70-770 mg/m3, while superficial flow rate was from 2.16 to 2.35 cm/s. The obtained air treatment degree was 9-100%, while maximum biofiltration rate amounted to 54 g/(m 3źh).

Badano proces biologicznego rozkładu par metyloizobutyloketonu w strumieniu powietrza i wpływ tego procesu na działanie biofiłtru. W trakcie tych badań określono przydatność w procesie biofiltracji trzech różnych wypełnień naturalnych, takich jak: szyszki olchy, kora sosnowa oraz mieszanina kory sosnowej i kompostu w stosunku objętościowym 2:1.

The process of biological decomposition of metyl isobutyl ketone vapours in air stream was studied experimentally. The effect of this process on biofilter performance was also analyzed. Usability of three natural beds, i.e. alder cones, pine bark and mixture of the pine bark and compost (with 2 : 1 volumetric proportion) was tested.
