Technologies for Anaerobic Digestion of Flushed Swine Manure

Hog farmers face a unique challenge to implement digestion — namely the low volumetric methane yield of wet swine manure.  The most common digester used on hog farms using flushing systems is the covered lagoon.  This presentation explores the technical feasibility of high rate reactors for low solids swine manure.  Systems compared are Contact Stabilization Reactors, Upflow Anaerobic Sludge Blanket …
