In line 2, it should be 17.1 g/cu.ft.
To figure, divide your ppm by 17.1, that will give you grains. Divide grains by
1000 and that will give you kilograins.
400/17.1/1000 = .0234 kg
At 10 gpm
= .234 kg/min or
14.04 kg/hr
Need to know the ration of anions to cations now. Assume 50/50
Now 7 kg/hr cation, and 7 kg/hr anion. Assume resin capacity of 14 kg/cu ft
anion and 21 kg/cu. ft cation.
Require 1/3 cu.ft cation resin per hr
Require 1/2 cu. ft anion resin per hr.
Double it to be safe and calculate for one regen each 12 hrs.
