Microwave Pretreatment of Fresh Water Hyacinth (Eichhornia Crassipes) in Batch Anaerobic Digestion Tank (RESEARCH NOTE)
The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...
متن کاملResults of batch anaerobic digestion test – effect of enzyme addition
The hydrolysis of lignocellulose is assumed to be the rate-limiting step in the anaerobic fermentation process. A fungal hydrolytic enzyme mixture was used to assess the enzymatic impact on different feedstocks for biogas production. The optimal conditions for enzymatic hydrolysis of rye grain silage, maize silage, grass silage, feed residues and solid cattle manure were determined in lab-scale...
متن کاملModelling 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...
متن کاملModeling 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...
متن کاملModelling of the temperature-phased batch anaerobic digestion of raw sludge from an urban wastewater treatment plant.
The disposal of excess sludge from wastewater treatment plants is a serious problem that needs to be addressed. Temperature-phased anaerobic digestion (TPAD) which combines thermophilic and mesophilic processes in one, brings together the advantages of both systems. The aim of the present work was to develop a simple kinetic model to describe the TPAD of sewage sludge in batch completely stirre...
