    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

  • How 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.

    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).

  • Anaerobic 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.

    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.

  • Effect 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
