In initial acid forming stage pH value may be around 6 or less. During methane forming stage pH value 6.5 to 7.5 is maintained. Feeding rate Faster feeding rate will not help in increase gas production. At higher feeding rate the retention period will be less and undigested Slurry may come out. So optimum feed rate should be maintained. 8

Chat OnlineExperimental Investigation on Biogas Production Using
The laboratory scale anaerobic digestion experiments were carried out with two phases one dry and other wet pressmud. The two variable temperatures and pressures are monitored. Thermocouples were used to measure the temperature of digester slurry. Pressure gauge was
Chat OnlineHow is biogas produced Gasum
Digestion carried out by these microorganisms creates methane which can be used as it is locally or upgraded to biogas equivalent to natural gas quality enabling the transport of the biogas over longer distances. Material containing organic nutrients is also produced in the process and this can be utilized for purposes such as agriculture.
Chat OnlineWhat is Biogas A Beginners Guide Homebiogas
Bio-slurry refers to the most decomposed stage of the organic matter after it has been broken down in the system. Bio-slurry sinks to the bottom of the biogas system and with the help of modern units like HomeBiogas is easily emptied out once accrued (usually an annual process).
Chat OnlineAnaerobic digestionWikipedia
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products as well as home fermentation uses anaerobic digestion.

Figure 2-1 A dairy farm anaerobic digestion system (RCM Inc. Berkeley California) In the second stage most of the organic acids and all of the H2 are metabolized by methanogenic bacteria with the end result being production of a mixture of approximately 55 to 70 CH4 and 30 to 45 CO2 called biogas. The methanogenic bacteria are slower
Chat OnlineBio-Gas Production large small-scale "home" renewable
Bio-gas is a mixture of methane (CH4) and carbon dioxide (CO2) produced by the break-down or digestion of organic waste such as manure vegetable matter sewage or even food waste. The gas produced is clean and burns clean providing a more healthy fuel than some alternatives such as wood.
Chat OnlineEffect of Effluent Recirculation on Biogas Production
The higher VFA in the effluent of the first-stage in the system with recirculation might be the reason for the higher methane production. Similarly Stabnikova et al. reported that 40 higher methane production was obtained by recirculation of effluent from the second-stage into the first-stage in anaerobic digestion of food waste. The authors

Chat OnlineThe Anaerobic Digestion Process An Introduction
Thus in the anaerobic digestion process methane bacteria provide the ultimate waste disposal system for a whole community of bacteria that grow together to provide the biological basis for what has become known as the "anaerobic digestion process" which occurs naturally in sludge digesters at sewage works and in damp putrescible deposits

Types of Small-Scale Digesters Fixed Dome Biogas Plants . A fixed-dome plant comprises of a closed dome-shaped digester with an immovable rigid gas-holder and a displacement pit also named compensation tank . The gas is stored in the upper part of the digester. When gas production commences the slurry is displaced into the compensating tank.
Chat OnlineA Novel Method for Kitchen Anaerobic and Aerobic Digestion
Viturtia et al. 1 inspected two stages of anaerobic digestion of fruit and vegetable wastes and achieved 95.1 volatile solids (VS) conversion with a methane. yield of 530mL/gVS. In a study performed by Lee et al. 2 FW was converted into methane using a 5-L continuous digester resulting in 70 VS conversion with a methane yield of 440mL/gVS.

The management of cattle manure (CM) has become increasingly challenging because its production continues to rise while the regulations on manure management have become increasingly stringent. In Korea most farms produce CM as a dry mixture with lignocellulosic bedding materials (mainly sawdust) making it impractical to treat CM by anaerobic digestion. To address this problem this study
