Advantages and Disadvantages of biogas digester

 Advantages and Disadvantages of biogas digester

Advantages  biogas digester

  • Generation of biogas and fertiliser (almost complete retention of the fertiliser nutrients (N, P and K)
  • Reduction of greenhouse gas emissions through methane recovery
  • Combined treatment of different organic waste and wastewaters
  • Reduction of solids to be handled (e.g. less excess sludge)
  • Good pathogen removal depending on temperature
  • Process stability (high-loads can be treated but anaerobic sludge can also be preserved for prolonged periods without any feeding)

 Disadvantages  biogas digester

  • Small- and middle-scale anaerobic technology for the treatment of solid waste in middle- and low-income countries is still relatively new
  • Experts are required for the design and construction, depending on scale may also for operation and maintenance
  • Reuse of produced energy (e.g. transformation into, fire/light, heat and power) needs to be established
  • High sensitivity of methanogenic bacteria to a large number of chemical compounds
  • Sulphurous compounds can lead to odour

biogas plant animation video about how biogas plant works and how gas convert in to bio CNG

biogas produce in digester tank by the action of anaerobic bacteria on feedstock or bio degradable material, this biogas transfer in to biogas steel scrubber to filter H2S (Hydrogen sulfide) purify gas for making of CNG Gas to have more filtration processes to filter CO2 carbon di oxide and H2O water and other impurities
