Iron removal from water

mike95490mike95490 Posts: 7,967Solar Expert ✭✭✭✭

I seasonally get iron in my water, and need to remove it before the main filtering.  Research I've done shows that "greensand" style filters can trap the iron and then be backwashed with potassium permanganate and then returned to use. (much like a water softener and brine)

I have limited power and pressure (and water) for backwashing, and wondering if anyone has solved an issue like this ? 

  I'm hoping a mild pressure and let it soak overnight might work for the backwash/recharge ? 

Use 2 tanks and swap them back and forth ?

    You can oxidize (various chemicals  or ozone or air) and then let it settle out in a holding tank.  No backwashing needed.

    As jonr said, oxidation is the usual method i.e. bubblier in a storage tank with a pressure tank beyond that... 
    "Main Filtering" what are you filtering out, whole house filters are normally not needed, they reduce the flow too much, and require maintenance.   
    This is a Solar site so I see no conflict in sending you to another site https://pumpsandtanks.com/index.php , good unbiased experts there unlike another well known plumbing site, Speedbump is our resident expert and I own the site and won't try to sell you anything, besides I have nothing to sell.

    We always rotate rain water to keep it fresh and chlorinated thru its storage cycle of 6 or 7 months.
    So, yea swap it!

    Or,  harvest the rain, there are only a couple ways to goof up rain water and dozens for ground source water.
