Abstract

Wastewater containing organic matter may be treated using a multi-zone apparatus. In a first zone, organic matter in the wastewater may, among other things, be converted to at least volatile fatty acids (VFAs) and, thereafter, a portion of the treated wastewater may flow to a second zone that may, among other things, convert the VFAs to methane.
