| Outline of Final Research Achievements |
A partial oxidation of digestate using Fenton reaction was evaluated to maximise methane conversion efficiency of the anaerobic digestion process. The lab-scale continuous experiment for over 6 months demonstrated that the unbiodegradable COD fraction of the digestate could be converted biodegradable ones by about 31%, resulting in corresponding methane production from the system.
Based on the experimental datasets and modifying IWA activated sludge models and anaerobic digestion model, a mathematical model to simulate the methane production, sludge concentration in the reactor and production of soluble inert which was the byproduct of the partial oxidation was developed.
