Modelling and Simulation of Co-digestion in Anaerobic Digestion Systems

Anaerobic Digestion Systems

ing the installation of anaerobic digestion systems and the equipment necessary to generate electricity from the methane produced and collected by these systems. There are several reasons these systems are being considered: decreasing onfarm energy costs by using methane to generate electricity; mitigating odor problems on livestock operations; and improving the handling of manure nutrients and...

Anaerobic co-digestion of organic wastes

Over the last years anaerobic digestion has been successfully established as technology to treat organic wastes. The perspective of turning, through a low-cost process, organic wastes into biogas, a source of renewable energy and profit, has certainly increased the interest around this technology and has required several studies aimed to develop methods that could improve the performance as wel...

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...

Modelling Anaerobic Digestion of Cow Manure to Predict Methane Flow Rate

Anaerobic digestion (AD) of biowastes is one of the most common ways to produce methane-rich biogas, which has considerable potential to replace the fossil fuel used in multiple applications, such as vehicular transportation, internal combustion engines, cogeneration of heat and power systems and many other systems. Many companies are involved in the design and construction of anaerobic digesti...
