ANAEROBIC DIGESTION
BREAKTHROUGH
Michigan State University
Anaerobic Digestion Research Education Center
(ADREC)
MSU ADREC anaerobic digest specialists carried out an independent third-party lab scale study to confirm beneficial impact of adding BIOLOGIC™ SR2 to Biomethane Methane Potential jar test reactors. Control (No SR2) tests and SR2 treated tests were carried out in triplicate to ensure valid results.
The
Challenge/Problem
To determine if low volatile solids destruction efficiency could be improved and if biogas generation rates could be increased above industry standard in digesters treating dairy
manure combined with liquefied food waste.
Success Achieved
Volatile destruction efficiency of reactors treated
with BIOLOGIC™ SR2 improved from 32% (not
treated with SR2) to 45% an increase of 41%
Specific Biogas Generation per Kg/VS added
to the reactors increased from 427 ml/gm
VS to 692 ml/gm VS an increase of 62%
Methane content of biogas 64 – 75%
Results achieved in 30-day trial
Results achieved with BIOLOGIC™ SR2 dosage
rate varying from 25 – 100 ppm
