| Abstract: | In order to develop a method for the removal of hydrogen sulfide via a biological process, two different packing materials
were tested to assess their capabilities as biofilter bed materials under variable conditions of two parameters: inlet gas
concentration and inlet gas flow rate. We detected a maximal elimination capacity (critical loading rate) of 515.1 (410.5)
g-H2S/m3·hr, and 415.5 (80.0) g-H2S/m3·hr, respectively, when polypropylene fibrils and volcanic stone were employed as supporting materials. The results of this
study show that the application of polypropylene fibrils might be a favorable choice as a packing material in biofilter for
the biological removal of hydrogen sulfide. |
