It is used for a variety of commercial and residential applications to minimize the damaging impact of hard scale. The process involves flowing water, that contains calcium and magnesium (water hardness) ions, through a sodium charged resin media where the hardness ions are physically exchanged for sodium ions.
It is often expressed as ‘grains-per-gallon’ (gpg) where one grain of hardness is equivalent to 17.1 milligrams per liter (mg/l) or parts per million (ppm) of water hardness. By definition, water is “soft” when it contains less than one grain of hardness. The capacity of a softening devise is a measure of how many grains of hardness can be removed before becoming exhausted.
OptiPure softening systems utilize Strong Acid Cation (SAC) softening resin which removes specifically calcium and magnesium hardness minerals. Only these hardness minerals and some forms of iron are removed.
Ion exchange changes the physical characteristics of water, which may not result in the right water chemistry for some applications. And, it is most often used in a ‘system’ that includes sediment and chlorine, taste & odor reduction.
Softening systems are available in both of the compact QT and FX configurations with a range of capacities. OptiSoft systems are self-regenerating softeners for high capacity/high flow applications
QTSFT-3 softening system softens water and reduces sediment, chlorine, taste & odor. It is a recommended for use with espresso and specialty tea applications. Softened water is not recommended for coffee brewers.
