Figure A-15. Amberlite IR-120 plus iso-capacity data regeneration-5 Ibs. H2S04 (66 Be)/cu. ft.
With a 5-pound H2SO4 (66 degrees Be)/cubic foot regeneration level, the book capacity = 15.1 kilograins/cubic foot.
The alkalinity correction factor can be found in figure A-19.
Then
The corrected capacity = 12.4 kilograins/cubic foot.
Then
Use equipment factor = 0.8.
.
. . Design Capacity = 9.9 kilograins/cubic foot.
