Experimental research of odours arising during the process of biofiltration
Santrauka
Investigations were carried out using a biofilter – a laboratory new generation air cleaning device with straight and wavy plates. Acetone, xylene and ammonia vapours were filtered through the biofilter’s packing material during the investigations. The biofilter’s structure is particular in that its packing material consists of polymer plates arranged vertically next to each ot her which produce a capillary effect of humidification. The plate-type structure of packing material with spaces (4±0.2 mm) between the plates reduces the device’s aerodynamic resistance. After completing experimental research it can be stated that odour reduction was 5 to 10 % greater when a wavy structure was used.
