Higher solid content feed to digester have potential to increase the efficiency of conversion
of organic waste material to biogas. But the higher total solid content can cause reduction in
mass and heat transfer between bacteria, enzymes and substrate in the digester.
Hydrodynamics is a major factor that contributes in formation, mass transfer, structure and
metabolism of microbial community in an anaerobic digestion process [1]. Agitation of
anaerobic slurry is important to achieve firstly the supply of uniformly distributed substrate …
