  • Start up here, water question

    just found out our well here in NH has high iron and manganese.

    what do others do to filter this crap out?

    any advice greatly appreciated!

    thanks!

    Because water quality varies so much from area to area, I would simply go to a specialist supplier of treatment kit and see what details they need and see what they advise - then you can get guarantees to go with the kit. What works in one situation, e.g. volumes and contamination levels, might not work very well, or work long term in another. There appear to be plenty of people advertising on the internet. For what it is worth, I think it would be worth a fair bit extra for an automated regeneration system - of whatever solution you go for - you will have enough on your plate without worrying about having to regenerate at prescribed intervals.

      Thanks!

      just one more thing for me to worry about.... I hope this doesn't complicate it too much... gotta love NH wells.

        I have brewed at a brewery where they used a reverse Osmosis system because the water was not perfect for brewing. We added back what was needed for the beer style.

          Pretreatment required

          RO is great for getting your mineral profile down, but with Iron/Manganese you'll need to pretreat the water before RO in any case. Manganese is tricky to remove--it depends on a lot of factors. In industrial settings, I've used potassium permanganate oxidizer in a greensand filter. This works for iron as well. However, there are other factors to consider, so in this case, I'd second the recommendation to find a local company with experience.

            Yes Pre-treatment is required

            Depending the the levels of Iron/Manganese in your water, if it's low enough, a water softener can filter it out. But, you will need a resin cleaner system in your brine tank. But I would definitely go with RO after that. If you have a water report send it over I will take a look at it for you.

              We're up to our elbows in a project right now at an aquaculture research station treating well water with Mn and Iron.

              The place to start is with a good water test. Nearly any contaminant is treatable - but we have to know concentrations of the contaminants. I'd not recommend Ward Labs for this purpose - at least not the typical beer brewing water tests I see.

              This is what we use to support the design/spec'ing of treatment:

                    You can try Second Wind Enviornmental. They do all sorts of systems and they are here in NH.

                      Just to avoid confusion...

                      If you've read this thread and are thinking RO is a good approach to treat iron and manganese... It's NOT.

                      These contaminants are common in well water, along with H2S, and are all very "treat-able" - but they need to be treated PRIOR TO delivering the water to an RO system. Some of the treatment approaches that leave excess sodium in the water (like a water softener) will likely require an RO afterwards.

                        What works good on my home system is filters. My well water has a high content of dissolved iron in it. leaves a red slime type coating on the pre filters. I use two different filters, a 5 micro pre and then a .5 micron that takes out the iron. The water before filtering has a metallic taste to it from the iron. After filtering metallic taste is gone. I brew a lot of lagers and after filtering, it makes great beer. My well water is acidic around 6.1 out of the tap. I don't have to treat it at all for the ph, mash brings it right in where it belongs with starting at 6.1.

                          Dissolved iron, a.k.a. Ferrous iron 2+ , can be brought out of solution - which turns it into undissolved ferric iron. Undissolved iron can be filtered out like any other particulate. To force this ferrous->ferric change an oxidant like chlorine, pot perm, peroxide, or even air is typically introduced, and then given some time to react in a holding tank. In very small/low flow systems the turbulence in the flow at a filter's surface will cause the same change. If this approach works for you - I'd say go ahead and use it. You'd have to do some testing to see how much un-reacted ferrous iron is passing through.

                          Iron issues in well water are commonly present with a couple of other issues: manganese, and hydrogen sulfide. The manganese can also be brought out of solution by an oxidant, and other means; and if you had H2S, you'd know it via the rotten egg odor.
