Abstract
An anaerobic biological reactor comprising an anaerobic digester having a chamber configured to receive a microbial suspension, a chamber inlet configured to direct an organic waste stream into the digester, and ion-exchange fibers within the chamber in position to contact and chemically react with microbial suspension received into the chamber. A method for treating organic waste with a methane-producing anaerobic biological reactor comprise providing a methane-producing anaerobic biological reactor comprising an anaerobic digester containing a microbial suspension comprising acetogenic bacteria, methanogenic bacteria and a plurality of ion exchange fibers, introducing organic waste into the anaerobic digester, maintaining the microbial suspension in contact with the organic waste and at least a portion of the plurality of ion-exchange fibers for a period of time and under conditions sufficient to treat the organic waste and produce methane, and removing the treated organic waste and methane from the anaerobic digester.
