| APPLICATIONS: |
| ProSoft™ High Porosity is ideally suited for use in severe operating conditions,
especially where standard grade resins are known to fail due to thermal, osmotic, or oxidative attack. It has
a high level of DVB which gives it a longer service life when softening aggressive waters where moderate
de-crosslinking isanticipated (such as a hot process softener). It is intended for use in water softening,
deionization, and chemical processing applications. |

| 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 ProSoft™ High Porosity. |
