Using Fly Ash to Decrease Seepage Rate In Pond
Using Fly Ash to Decrease Seepage Rate In Pond
(OP)
Hello,
I want to use fly ash to decrease the seepage rate in runoff control structures at a feed yard. Fly ash is readly available at a local coal fired electric generating plant. I need to know how to calculate how much fly ash I will need. Can anyone help?
Thanks

I suppose this is an established use for fly ash, but you might consider running a chemical analysis of it. Somewhere I read that mercury can wind up in fly ash, though I don't know how it would survive the heat. Anyway there are other heavy metals that could also be concentrated into the ash, so you might ask the question just in case.
I think the process is that somehow the mercury winds up as HgS which anaerobic bacteria breakdown for energy, converting the Hg into a mobile form and off into the water. Most likely the high organic content of the runoff is in a low oxygen state. At regulatory levels for mercury in the ppb range, it doesn't take much.
