Harvesting Methane from Water

Hello I have a rare situation occuring in my well here in Ohio. After recently testing the water I have high levels of naturally occurring CH4 (Methane). What I am looking to do is harvest the Methane from the water through aeration and store it in a tank. Has anyone done this? I look through and see BiOgas as an alternative but the well is naturally occurring.

What my plan is setting up an aeration tank where the water is stored and pumped into the house. Then the methane will be pulled through a fan to the exterior of the house into another tank. Of course over flow switches will be installed on both tanks to prevent busting or over filling.

Any suggestions?

If you have a way to heat the water you'd get more of the gas coming out of solution. I would think with all the fracked wells in the US that your situation is not all that rare and lots of people could be doing this.

[Edit to add some additional thoughts]

You might want to try this without the fan. Methane is lighter than air (density at 25 C is 0.65 g/l, plain air is 1.2 g/l) so if the containment vessel is allowed to stratify the methane will collect at the top. A small pump could then harvest the methane and move it to your storage tank.
I can't take it! You are too smart for me! Here is the tiny ad:
