Anaerobic digestion of swine manure: Sung-Hwan farm-scale biogas plant in Korea
In order to increase the use of biogas plants in Korea, a farm-scale biogas plant with a working volume of 200 m was constructed at the pig farm in Sung Hwan, Korea as a demonstration project supported by the Korean government. This plant mainly consists of an anaerobic digester processing daily 10 m pig manure and a dual-fuel engine-generator to produce heat and electricity. Digestion takes pl...
متن کاملThe effects of digestion temperature and temperature shock on the biogas yields from the mesophilic anaerobic digestion of swine manure.
In order to obtain basic design criteria for anaerobic digesters of swine manure, the effects of different digesting temperatures, temperature shocks and feed loads, on the biogas yields and methane content were evaluated. The digester temperatures were set at 25, 30 and 35 degrees C, with four feed loads of 5%, 10%, 20% and 40% (feed volume/digester volume). At a temperature of 30 degrees C, t...
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 کاملThe effect of cefazolin on biogas production from thermophilic and mesophilic anaerobic co-digestion of dairy manure and waste milk
* Corresponding author ([email protected]) Abstract: Antibiotic residues in animal waste from concentrated animal feeding operations are of considerable concern because of the potential development of antibiotic resistant bacteria in the environment and the effect of these residues on manure treatment systems. The objective of this study was to determine the effect of cefazolin (10 mg L) dur...
متن کاملMesophilic digestion kinetics of manure slurry.
Anaerobic digestion kinetics study of cow manure was performed at 35 degrees C in bench-scale gas-lift digesters (3.78 l working volume) at eight different volatile solids (VS) loading rates in the range of 1.11-5.87 g l-1 day-1. The digesters produced methane at the rates of 0.44-1.18 l l-1 day-1, and the methane content of the biogas was found to increase with longer hydraulic retention time ...
