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

ADVANTAGE :-
• Biogas Generation is 1150m3/day (96 KWH)
• Cost of the Plant can be Recovered in Just 3 Years
• Minimum Operation & Maintenance Cost
• No External Power Requirement for ETP.
• Water can be Recycled after Tertiary Treatment

SALIENT FEATURES :-
• COD Reduction :- 80 – 85%
• Biogas generated :- 0.5 to 0.55m3 kg COD reduced
• 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.
