Hydraulic Properties

Pressure Drop: The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at varioustemperatures.

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 Pure PC200.
