Operators Briefing Note – Anaerobic Digestion Operators Guidance Note – Effective Digestion of Food Waste

2.0 What are the challenges? There are two groups of ‘biogas generating’ organisms available within an Anaerobic Digestion process: acetoclastic methanogens and hydrogenotrophic methanogens. Food waste has a high nitrogen content due to the high protein component. During anaerobic digestion this generates a high level of ammonia which is toxic to the acetoclastic methanogens. Whilst biogas prod...

Modeling of Anaerobic Digestion of Complex Substrates

A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...
