Well Water Treatment & Options

My wife and I are in the process of building our home on twelve acres in Tennessee.  We are located on the Cumberland Plateau and our area is noted for its bad water.  We have drilled a well (246 feet deep, with the water coming to within 18 feet of the surface) and we get approximately eleven and a half gallons per minute.  The well driller couldn't believe it (most average three gallons per minute) and I've spoken with my surrounding neighbors who average between one and a half, up to three gallons.  Some wells have gone dry, so I am super thankful for the flow that we get.  

Our problem is IRON and it's really bad!  As of now we have a Bison hand pump on the well, but would like to run it into the house too.  We do have city water at the road and the tap installed (we could connect), only wondering what other folks have done in a similar situation?  We've spoken with some water treatment/conditioner companies and they are not cheap.  We eventually want to go off-grid and wanted an affordable and reasonable system to administer.  Any suggestions?  Blessings...Hugh

My reply is probably rubbish, since I have no experience in water treatment and you want to go off grid. I am wondering whether an electrolysis system might be effective enough. With a Direct Current Iron in solution will deposit on the negative terminal. Given enough time, electrical current, and a large enough surface area you could certainly extract iron (along with what ever other positive ions may be in your solution). Whether it would be practical, even if you lived in a sunny climate year round, I somewhat doubt. If you are off grid you probably have other things to use your generated power for. Eventually the iron deposited would block the electrode and you'd have a lump of iron and need to get a new electrode. Ever think of going into blacksmithing :) )

One of the biggest issues with high iron levels is that iron can act as a growing medium for bacteria which needs to be managed.
Have a look at this YouTube video.  From my reading, hydrogen peroxide formed in rain is the thing that helps plants grow better, so I think that it is safe to use.  Food grade hydrogen peroxide is widely used so we probably eat huge amounts of the stuff.

My first thought was magnets.. looks promising:

You can also make a Permies friendly filter with bio char, peat moss, and sand.. which could be composted when “full”? I’m sure some scientist will argue about the accumulation of heavy metals, etc., but I believe in the alchemical power of microbes to deal with just about anything, and if that’s a concern.. use this compost for non edibles.
