How does a biotrickling filter remove other compounds – say, methyl mercaptan, DMS?
Methyl mercaptan and Dimethyl sulfide (DMS) are organic reduced sulfur compounds and are oxidized by heterotrophic bacteria as described above. It is important to note that the autotrophic bacteria grows under different pH and process conditions than heterotrophic bacteria; thus, the system should be designed to accommodate both these bacterial groups in different media “zones” to allow for a well functioning, and optimally performing system.
