    Is this an atmospheric (un-pressurized) tank? If so, a UV recirc loop would be customary.

    About the only time we spec them is for pretreatment to an RO System, and boiler feed water.

    A softener can be used for dissolved (ferrous, Fe++) iron, as long as the iron concentration is low. But this really isn't the best approach. Have you resolved your situation?

    First - call your water supplier and determine what disinfectant they are using. Will be chlorine OR chloramines. Once we know that, then yes - the primary sizing criteria to treat chlorine (with...

    Dick - your Total Hardness is 584 ppm - or 34 grains per gallon. Typically anything over 10 gpg needs a softener before an RO, or you'll scale the membranes. Between 5 and 10 gpg a softener is...

    yes - I agree . An RO system that can produce 20 gpm (28,800 gpd) is overkill for a 10 bbl brewery. Hence the recommendation for an atmospheric holding tank. We can spec this all out for you,...
