Notes:
(1) Total anions equal total cations
(2) Total hardness equals calcium plus magnesium (all as ppm CaCO3)
Sodium Cation Exchanger. See Figure 31. Use this treatment to

reduce water hardness without affecting the alkalinity. The exchanger tanks
are often hooked up in parallel, each unit being sized to handle service flow
while the other is regenerating.
