TDS: Softeners remove manganese best if the total dissolved solids (TDS) of the water is low. When TDS is high, other minerals in the water compete with the manganese for space on the resin and can even displace manganese which has attached to the resin. Water with <500 ppm TDS works best for manganese removal by a water softener.

Mar 20, 2017 · A poor ore and pig iron high in silicon and manganese require more power than a rich ore and pig iron low in silicon and manganese. This was also found to be the case in California.
