Design Data

Title	Inlet	Outlet
Flow	450m3 / Day	450m3 / Day
pH	4.5	5.5 - 9.0
BOD	40000-50000 mg/L	< 100 mg/l
COD	90000-120000 mg/L	< 100 mg/l

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
