ResinTech CG8-F is a premium grade, high capacity, gelular, sulfonated, polystyrene cation resin supplied in the sodium or hydrogen form as moist, tough, uniform, spherical beads. ResinTech CG8-F is intended for use in all water softening, dealkalization, deionization and chemical processing applications.
The chart below shows the expected pressure loss per foot of bed depth as a function of flow rate, at various temperatures.
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 chart below shows the expansion characteristics of ResinTech CG8 in the sodium form.
