Research on the Aerodynamic Resistance of Trickle Biofilter La elinio biofiltro aerodinaminio pasiprie inimo tyrimai

A four – section trickle biofilter was constructed for experimental research. The filter was filled with the packing material of artificial origin. The material consists of plastic balls having a large surface area. The dependence of biofilter aerodynamic resistance on supply air flow rate and the number of filter sections was determined. The aerodynamic resistance of the biofilter was measured in two cases. In the first case, the packing material of the filter was dry, whereas in the second case it was wet. The experimental research determined that an increase in the air flow rate from 0.043 m/s to 0.076 m/s causes an increase in biofilter aerodynamic resistance from 30.5 to 62.5 Pa after measuring four layers of dry packing material. In case of wet packing material, biofilter aerodynamic resistance after measuring four layers of plastic balls increases from 42.1 to 90.4 Pa. Article in Lithuanian Eksperimentiniams tyrimams atlikti sukonstruotas keturi sekcij la elinis biofiltras. Filtras u pildytas dirbtin s kilm s krova, sudaryta i didel pavir iaus plot turin i plastikini rutuliuk . Naudojant krov , skirt introdukuot mikroorganizm asociacijoms kultivuoti, nustatytos biofiltro aerodinaminio pasiprie inimo priklausomyb s nuo tiekiamo oro srauto grei io ir sekcij skai iaus. Biofiltro aerodinaminis pasiprie inimas matuotas dviem atvejais: esant sausai ir sudr kintai krovai. Nustatyta, kad didinant tiekiamo oro srauto greit nuo 0,043 iki 0,076 m/s, renginio aerodinaminis pasiprie inimas i matavus keturis krovos sluoksnius padid ja nuo 30,5 iki 62,5 Pa tuo atveju, kai krova sausa, ir nuo 42,1 iki 90,4 Pa, – kai krova sudr kinta.
