Hi all,
Does anyone know of studies / papers etc on methane production vs Chemical Oxygen Demand C.O.D of waste water.
Also Time production curves.
Cheers & Thanks
Methane Production Vs. C.O.D

methane:COD
fchartier,
If you are just looking for a general answer, 5.607 cuft methane/lb COD consumed @ 35 deg C. Adjust for temperature (273.15 + T1)/(273.15 + 35) and and %methane and that is "generally" what you'll produce. But, Bob is correct anaerobic digestion is heavily dependent on the amount of COD and type of substrate being fed, and there are tons of studies out there.
As far as time production curves, I doubt microbes work harder in the morning compared to night, as long as they are happy they are going to produce at a constant rate.![:)](./images/smilies/icon_smile.gif)
hope this helps a tid bit.
