MN,
What is the goal? If you talk to vertex and other diffuser manufacturers, they all have charted how much O2 their diffusers add to the water for a given CFM/depth. Are you trying to see something different. Please let us know.
Also. the fish will be consuming O2, how are you going to account for their usage?
Finally, I assume the BOW will be frozen over, or will there be water to air contact?
I am trying to develop a reproducible science experiment in a frozen pond setting. Specifically testing for DO amounts diffused into a BOW over x amount of time using different intermittent solar direct drive aeration designs.
If you talk to vertex and other diffuser manufacturers, they all have charted how much O2 their diffusers add to the water for a given CFM/depth.There is no data on this type of aeration system as aeration has never been done this way before.
Are you trying to see something different. Please let us know.What I might have here is a way to aerate frozen water without the creation of thin ice. The safest way to aerate in the north. I had completed some proof of concept tests last winter but with the short winter last year I wasn't able to set up any "good science" reproducible testing.
Also. the fish will be consuming O2, how are you going to account for their usage?Yes, the fish and the dying plant life will be consuming the DO. When running, with the bio loads, this system will keep the DO well above 8 or 9ppm in this pond setting (at least it did last winter but how much of that was because of photosynthesis). How long will the "banked DO" last once it is shut off? Once it drops to say 5ppm , how long does it take for the system to get the water back to the 8-9ppm?
Thanks for the response HF
