摘要

Method for cleaning gases (21) containing hydrogen sulfide in a biofilter arrangement (4) comprises distributing liquid from a liquid reservoir (10) directly within a filter material (6) to moisten the filter material. An independent claim is also included for a biofilter arrangement for cleaning gases containing hydrogen sulfide. Preferred Features: The liquid is fed into the filter material from a liquid reservoir using a capillary action. The liquid reservoir is filled with water (11), especially rainwater, using gravitational force.
