Anaerobic Digestion
APS Digester Technology
This Anaerobic Phased Solids (APS) digester process incorporates a new, high-rate bioconversion technology
developed by Dr. Ruihong Zhang in the Biological and Agricultural Engineering Department at the University of
California, Davis (UC Davis).
Dr. Zhang’s process exhibits significant advantages over existing, anaerobic digestion technologies. These
advantages stem from several innovative design features that allow optimum environmental conditions for the system’s
microorganisms, resulting in significantly shorter retention time with an expedient and efficient conversion of organic
feedstock into biogas and beneficial value-added byproducts.

Definition
Anaerobic digestion is not new; it has existed about as long as life has been present on earth.
Anaerobic digestion, a naturally occurring process, is the bacterial breakdown of organic materials
and by definition is an anaerobic process meaning that it proceeds in the absence of oxygen.
Anaerobic digestion is currently a worldwide-accepted technological process incorporated in the
digestion systems of sewage and municipal wastewater plants with thousands of these systems
currently in operation.
