| 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™ Nitrate in the chloride form. |
