MSD is designing and building an anaerobic digestion facility at the Little Miami treatment plant to process waste solids from the Little Miami, Polk Run, and Sycamore Creek treatment plants on the east side of Hamilton County. Waste solids, also known as treatment residuals, are removed from wastewater during the treatment process.
Anaerobic digestion is a biological treatment process for treatment residuals. Bacteria break down the residuals - in the absence of oxygen - into biogas and biosolids. The process destroys pathogens and reduces the volume of the residuals. With this project, treatment residuals will be thickened, anaerobically digested, dewatered, and hauled off site for beneficial reuse.
Here's the current project status:
