| description | Process
instability often occurs in anaerobic digestion (AD) due to inhibitors,
such as the high sodium content in food waste. Recent studies have reported
that magnesium can reduce the sodium ion’s toxicity towards methanogens. This
study aimed to analyze the effect of magnesium addition to Volatile Solids
Destruction (VSD), Chemical Oxygen Demand (COD) reduction, and biogas
production in AD of food waste. The experiment consisted of two phases, the
control phase and the experimental phase, without and with MgSO4, respectively. The
control phase results were: average COD reduction, VSD, and methane yield up to
80.9%, 87.6%, 340 mL
CH4/gr VS/day, respectively. The experimental
phase results were: average COD reduction, VSD, and methane yield up to 78.5%,
83.9%, 125 mL CH4/gr
VS/day, respectively. Overall, the study’s results showed that
MgSO4 had a negative impact on VSD and methane yield. The addition
of MgSO4 seemed to cause instability in the AD system, which
resulted in a decrease in the VSD value and a decrease in the methane
concentration. |
