| APPLICATIONS: |
| ProSoft™ Fine Mesh is ideally suited for use in industrial softening applications
because of its high capacity, uniform particle size, and good physical stability. It is intended for use in
all water softening, dealkalization, 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 25 to 50 percent. This will remove any foreign matter and reclassify the bed. The graph
above shows the expansion characteristics of ProSoft™ Fine Mesh in the sodium form. |
