Features:
- Complies with FDA regulations (paragraph 21 CFR173.5)
for potable water applications.*
- Uniform particle size, low pressure drop
- Superior, physical stability
- Organic fouling resistance, high operating capacity
* 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 to 75 percent. This will remove any foreign matter and reclassify the bed. The graph above shows the expansion characteristics of ProSelect™ General Purpose in the chloride form. |
