I am trying to decide whether to use my pH neutralizer predominantly for pH adjustment or for maximum Iron removal also. And whether my Softener can assist with iron removal if needed.
My 9x54 pH neutralizer is now setup with a mixed media bed consisting of a 40 lb. gravel base, 1.0 cu. ft. of Birm, 0.50 cu. ft. of Filter Ag, and an unknown amount of Calcite. It seems to be doing a decent job removing the iron, but lacks the pH neutralizing qualities I need. Green staining appears on fixtures within 6 months of adding Calcite.
Currently, the raw water pH is 6.4 and post neutralizer (kitchen faucet) it is at 6.5.
I have some Iron, the amount varies. Last year's laboratory water test showed 0.19 mg/L . My recent personal testing results, using my Hach kit, shows aprox. 0.075 mg/L at raw water and ND (none detected) post conditioning.
I would appreciate any advice on the options I am considering.
One option is to use my current pH neutralizer tank with a mixed media bed (TBD) and to purchase and install a new air injector valve, like the Clack or the Fleck AIO. This would allow me to oxidize the Iron, filter it out, raise the pH, and get rid of the existing air injector which will eventually ruin my new pressure tank. Will I be able to remove the existing contact/retention tank, or is it better to use it as an off-air tank? Should I replace my 9x54 tank with a larger one so that I can add more Calcite and have room for the air space? Or just change the mixed media bed to better address the pH?
Another option (which I would prefer), is to rebuild and use my existing, malfunctioning, Fleck 5600 12-day valve on the pH neutralizer tank with a new bed of only Calcite? Calcite/Corosex blend? This would seem to allow longer periods of proper pH adjustment because of the volume of Calcite compared to just the small amount which is added in the mixed media bed now. Will Ferrous Iron or Ferric Iron will be filtered by the Calcite bed?
Will my 1.0 cu. ft. softener and its media remove any remaining Ferrous Iron or Ferric Iron that the pH media doesn't, without fouling it? Should I change the resin to a more iron tolerant one?Will a more frequent backwashing regimen be required because of the higher Iron content water which the softener may be subjected to. My current Hardness is 9 gpg/153.9 mg/L.
