    Bought a house that has a birm filtration system that isn't doing the job. Would like to replace the existing equipment with something that will work. Going to remodel the inside in a year or so and don't want the new bathrooms to orange like the current tiles.

    Based on reading here, I went and had NTL test my well water. There is Iron Bacteria (not tested, but my toilets have lovely black scum). Here is a summary of the test, with the complete test attached as an image.
    Iron 7.711 mg/L
    Manganese 0.513 mg/L
    Hardness 330 mg/L
    Turbidity 87 NTU
    Calcium 89 mg/L
    Lithium 0.013 mg/L
    Magnesium 27.51 mg/L
    Potassium 4.7 mg/L
    Silica 28.4 mg/L
    Sodium 14 mg/L
    Strontium 0.18 mg/L
    Zinc 0.082 mg/L
    Alkalinity 300 mg/L
    Total Dissolved Solids 400 mg/L
    Chloride 48 mg/L
    Acetone 0.05 mg/L
    pH 7.0
    Iron Bacteria is present

    Local place recommended an Ozone injection system to avoid Chlorine, another one recommended running two softeners in series. I see a hardness and iron problem and would rather address those with a filter and then soften after. All I know is what I've read here though, so please feel free to send me down the right path.

    Thank you,

    Sean

    I think for the amount of iron that you need a separate iron like this one http://rainfresh.ca/product/iron-removal-filter/ ( someone (s) on here will probably specify a preferred brand. ) then a water softener . how many people are in your household and we can give you an idea of the size softener that you need.

    Ummm, no. Ignore the "specs" on most equipment. It may technically work for a short amount of time but you are asking for trouble with that type of low end unit. Adding air to bacteria will do wonders for increasing it even higher.

    Iron 7.711 mg/L Very high
    Manganese 0.513 mg/L Very High
    Hardness 330 mg/L Moderate, easily treated
    Turbidity 87 NTU Expected due to high iron
    Calcium 89 mg/L
    Lithium 0.013 mg/L
    Magnesium 27.51 mg/L
    Potassium 4.7 mg/L
    Silica 28.4 mg/L High, not worth treating
    Sodium 14 mg/L
    Strontium 0.18 mg/L
    Zinc 0.082 mg/L
    Alkalinity 300 mg/L
    Total Dissolved Solids 400 mg/L Moderate, ok
    Chloride 48 mg/L
    Acetone 0.05 mg/L Likely due to new plumbing, this will usually drop quickly
    pH 7.0
    Iron Bacteria is present

    Chlorine injection, contact tank, to kill the bacteria and remove the majority of the iron, in order to properly design a system for you, we would need to know what type of well/distribution do you have. Can you post pictures.

    What is the gas tank for?

    Old school design, where is the birm tank? Can you post a picture of the plumbing there?

    Since you have bacteria, we would normally recommend chlorine or ozone injection. Followed by a KL system and a GAC to dechlorinate, softener, but this starts to get difficult as we are getting into so many tanks. Are you planning on replacing your old galvanized tank?

    Do we know that iron bacteria are in the water straight from the well or just have made a happy home in the toilets?

    I am open to replacing everything. The galvanized tank is 1974, the birm filter system and softener from 2007. It has never worked right. The "gas" tank is CO2 and not related to the water treatment, just happens to fit best right there. Used for carbonating water under the sink right above that location.

    Great question. I have no idea, is there a way to check? The splashed water is from me pulling water off the well to check flow. 4gal in 8 seconds or around 30gal/min.

    There are iron bacteria tests I'll do some looking if none of the regulars on here offer a tried and true test. Black slime can be many things Iron bacteria are usually stinky orange slime. They love our toilet tanks despite having a functional UV light in the system but they hate bleach or Iron out ( not at the same time.)

    It really comes down to budget vs. quality of water desired. Do you mind a little maintenance in order to get better quality water?

    Since you have not treated for iron bacteria in the past, a simple sanitizing of the entire plumbing and well system may be all that is needed.

    A simple and effective treatment method and something that could be added onto later if needed may be the way to go. A simple micronizer air injector before the galv. tank. (replace that with a new tank) then into a Katalox Light tank, then into a softener. Did they split the water to go to two Birm Filters?

    The two filters are run like two softeners. One runs then the other. Backwashes with clean.

    We did bleach bomb the well when I put in a new well pump, but the bacteria/black slime came back.

    Quality water I would like to have. Sick of having orange tiles in our master bathroom...

    Did you sanitize the plumbing when you sanitized the well? Everything must be completely disinfected or the bacteria can return in a short amount of time.

    If you just want to do it right, no problems, then a simple chlorine injection, contact tank, carbon tank, BB sediment filter then a softener should do the job.
