Engineered Anaerobic Digestion Utilizing a Thermophilic Media : 

Engineered Anaerobic Digestion Utilizing a Thermophilic Media By Barnett Koven 17th International Conference on Health and Environment: Global Partners for Global Solutions

Purpose of AD : 

Purpose of AD Waste CH4 + CO2 Fertilizer Resulting gases known as biogas Energy derived from biogas is considered carbon neutral Power Gen. CO2 Energy Heat Energy

Bacterial Process Overview : 

Bacterial Process Overview Complex organic matter Carbohydrates, proteins, fats Soluble organic molecules Sugars, amino acids, fatty acids Volatile fatty acids 2. Fermentation Acetogenesis Acetic acid CO2 + H2 CH4 + CO2 3. Methanogenesis 1. Hydrolysis 3. Methanogenesis

Hypothesis : 

Hypothesis A more effective reactor design will optimize biogas yield and raise the methane content The use of a thermophilic media will result in a more efficient process Each unit of waste has a set energy potential

Discussion : 

Discussion Anaerobic Digestion utilizing a Thermophilic media results in a more favorable biogas composition and a higher biogas yield Biogas yield peaks after just 11 days Each unit of waste has a set energy value Biogas yield will form a parabola when related to time

Implications :
