Full text | Abstract: This article presents the results of research into removing volatile organic compounds from waste gases while using bio-filters filled with mixtures of natural materials, such as peat, bark, jute, hemp and cotton. Experimental filtration beds were installed in a fatty-products manufacturing company above a fatty-waste catcher (a container into which waste water from all the production departments of the company were linked). The waste-gases were guided through the filtration beds. The estimation of the process efficiency was based on a chromatographic analysis of the waste-gases at the input and output of the bio-filters. The article also presents the results of investigation concerning the desorption of water solutions of cotton, jute, and hemp fibres, consisting the active part of the filters. After some months of exploiting the filtration beds, the biological material was taken from the beds and conditioned at a constant temperature up to a? constant mass. The results confirmed the differentiation of the sorption properties of the fibres used, and at the same time the differences between the efficiency of the various filters indicated by us. |
