water softener or birm to remove Fe/Mn?
Water tests for untreated water: pH 7.3, hardness 4.14 gpg, Fe 1.96 ppm, Mn 0.14 ppm, Turbidity 11. Started having problems with iron staining clothing etc. Since present treatment equipment is ancient (water softener/ cartridge filter) and we are planning on selling home soon, I've had 3 quotes for treatment equipment.
Quote 1: recommended water softener to remove iron, manganese. He had a portable water softener and when he ran my water through it, there was still some iron in it (ferric I assume since softener should remove ferrous right?). He suggested a water softener that uses salt and a cartridge filter before it for particulate iron. I asked about using a filter instead of a softener since it doesn't seem my water is too hard, so he gave me quote for a birm/calcite filter...would make the water a little harder, but not enough that I think I would need a softener too.
Quote 2 - 10" standard cartridge filter followed by a 1.0 cu ft metered controlled softener using potassium chloride. I expressed my concern it wouldn't remove the particulate iron but that is what the cartridge filter is for. (as in first quote)
3rd quote - iron/manganese reduction system 1 cu ft chemical free oxidation of ferric, ferrous, bacterial iron by air induction.(proprietary media blend?) Will require replenishment of ph Plus 1-2 times per year at dosage of 4 lbs/cu ft media. Is this also a birm?
Since it is less than 5 ppm Fe, I'm thinking the softener may be the most economical/easiest to maintain route.
Also hydrogen sulfide smell only in hot water...will chlorinating hot water tank fix this? Just started recently...could be seasonal I guess.
Your advice/thoughts would be appreciated!
