Hydraulic Properties
（1）Pressure Drop:
The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate, at various temperatures.
（2）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 below shows the expansion characteristics of DL 510 in the sodium form.
