Abstract

Thin stillage, a result of the ethanol-producing process, can be treated biologically in anaerobic reactors, which have demonstrated a high potential for energy recovery in terms of CH4 and H2 production. The effluent from the biological treatment of thin stillage can then be treated through physical-chemical processes, such as coagulation, mixing, flocculation and sedimentation. The goal of this work is to adjust the flocculation and sedimentation parameters for the effluent of an anaerobic reactor applied to the treatment of thin stillage, indicating whether water reuse can be practiced based on its final quality.
