give composition of material fed to biogas plant ? Name the nutrient left in slurry of plants
Answers
Mixing tank - The feed material (dung) is collected in the mixing tank. Sufficient water is added and the material is thoroughly mixed till a homogeneous slurry is formed.
Inlet pipe - The substrate is discharged into the digester through the inlet pipe/tank.
Digester - The slurry is fermented inside the digester and biogas is produced through bacterial action.
Gas holder or gas storage dome - The biogas gets collected in the gas holder, which holds the gas until the time of consumption.
Outlet pipe - The digested slurry is discharged into the outlet tank either through the outlet pipe or the opening provided in the digester.
Gas pipeline - The gas pipeline carries the gas to the point of utilization, such as a stove or lamp.
Answer:
Biogas is primiarly composed of methane gas , carbon dioxide and trace amounts of nitrogen , Hydrogen and carbon monoxide
The mixture of dung and water which enter the biogas plant in semi liquid form is called "undigested slurry " The undigested slurry undergoes a series of anaerobic digestion processes or fermentation in a biogas digester and is converted into combustible gas called biogas
