Features:
- Complies with USDA & FDA regulations (paragraph
21 CFR173.5) for potable water applications.*
- Macroporous structure
- Uniform particle size, low pressure drop
- Superior physical stability
- Low color throw (APHA No. 50 Max. as shipped)
* For potable water applications, the resin must
be properly pre-treated, usually by multiple exhaustion and regeneration
cycles, to insure compliance with extractable levels. |

| PRESSURE DROP — The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at various temperatures. |
| |
 |
| |
| BACKWASH — After each cycle the resin bed should be backwashed at a rate that expands the bed 50 percent. This will remove any foreign matter and reclassify the bed. The graph above shows the expansion characteristics of ProSoft™ High Porosity in the sodium form. |
