ADVANTAGE :-

  • Biogas Generations = 15360m3/day
  • Costing the Plant can be Recovered in Just 6 Months.
  • Minimum Operation & Maintenance Cost
  • No External Power Requirement for ETP.

 

SALIENT FEATURES :-

  • COD Reduction :- 60 - 65%
  • Gas Generated :- 0.5 to 0.55 m3 biogas per kg COD destroyed
  • Anaerobic process thus oxygen from external source not required and no limitation of a transfer of oxygen which is sparingly soluble.
  • Practically no power requirement since no internal mixing /aeration required.
  • Generation of methane rich biogas which can be used to generate power
  • Minimal sludge production due to higher sludge retention time.
