Dairy Manure & Food Waste Anaerobic Digestion Breakthrough Michigan State University Anaerobic Digestion Research Education Center (ADREC)

Challenge:

Michigan State University’s ADREC sought to improve volatile solids destruction efficiency and increase biogas generation in anaerobic digesters treating dairy manure combined with liquefied food waste.

Treatment Plan:

SciCorp engineers implemented a lab-scale study using BIOLOGIC™ SEPTIC to determine if the digestion process could be improved. The study was conducted with both treated and untreated reactors to compare results.

Success Achieved:

  • 41% increase in volatile solids (VS) destruction efficiency (from 32% to 45%)
  • 62% increase in biogas production per kilogram of VS (from 427 ml/gm to 692 ml/gm)
  • 35% reduction in digester discharge solids
  • 92% reduction in foam formation
  • Methane content in biogas ranged from 64-75%

Long-Term Benefits for Biogas Digesters:

  • Increased biogas generation means higher electrical power output and revenue
  • Improved efficiency reduces waste solids, cutting operating costs
  • Enhanced digester capacity allows for higher organic loads
  • Lower environmental impact and carbon emissions

How This Benefits Your Septic System:

BIOLOGIC™ SEPTIC can enhance your septic system's efficiency by improving waste breakdown and reducing sludge buildup, ensuring better long-term performance and fewer pump-outs.
