I'm in the first stages of choosing a replacement for the 30 year old iron filter in our newly-acquired rural home. We've got well water with these stats (1-3 had via a laboratory water test):
(1) iron=1.7ppm
(2) manganese=0.296ppm
(3) ph= 7.4
(4) hydrogen sulfide is detectable by nose but not heavy
My thought is a standard greensand filter (i.e., with permanganate). Re/the possibility of Pyrolox or MangOx, I measured the flow rate just after our well tank using the unscientific bucket method and got 15gallons/minute (I'm on a shared well without immediate access to the pump, if that matters).
Additional info: hardness=17.4g/g per laboratory test (though we got merely 5-7 on the store-bought test kit). So the system's got the softener after the iron filter. The softener is working well and getting the hardness level to about 3g/g. The unit to be replaced would appear to be merely a birm filter, since there's no attached supply reservoir and I'm guessing that the pyrolox-type media weren't around 30 years ago. Re/media amount and tank size for the iron filter, we're just two people.
Last thoughts: I hesitate to go the Pyrolox or MangOx route for fear of insufficient backwash flow rate. I'm also unsure of dissolved oxygen levels, though the lab results yielded 7.7mg/l on a sample held way too long and not tested on site. So greensand seems to me best. But what do the more experienced members think?
I look forward to hearing what you've got to say.
