Mixed Bed Resin Capacities

These capacity numbers are for new resin. For regenerable applications, it is recommended that a dosage of 12 lbs per cubic foot of hydrochloric acid be applied to the cation resin portion and 13 lbs of sodium hydroxide per cubic foot be applied to the anion portion of the mixed bed resin to get about 80% of the as-new resin capacity and provide self-neutralizing waste.

Total Capacity = 9.6 kilograins per cubic foot

Capacity to 1 megohm endpoint = 7.2 kilograins per cubic foot

Capacity to 15 megohm endpoint = 3.6 to 5.0 kilograins per cubic foot
