Regeneration
| Regenerant | Concentration | Level (100% basis) | Temperature (max.) |
|---|---|---|---|
| NaOH † | 4% | 80 – 96 kg/m³ (5 – 6 lb/ft³) | 60°C (140°F) |
| Na₂CO₃ | 5% | 112 – 128 kg/m³ (7 – 8 lb/ft³) | 60°C (140°F) |
| NH₄OH | 5% | 80 – 96 kg/m³ (5 – 6 lb/ft³) | 60°C (140°F) |
† NaOH is recommended. ‡ Regeneration level may be lower for counter-current regeneration systems.
Hydraulic Characteristics
Bed expansion as a function of backwash flowrate at 25°C (77°F) is shown in Figure 1. Pressure drop data as a function of service flowrate and viscosity is shown in Figure 2.
