Softening Resin
SWT logo ProSoft™ Gold

SWT found a way to save you some money here and still get the job done. A 7% crosslinked softening resin that is for low or non-chlorinated waters — ProSoft™ Gold is perfect for well water and non-turbulator applications. It has excellent exchange capability, and every bag is prewashed and rinsed so that you don't have to do it in the field.

Features:

  • Complies with USDA & FDA regulations (paragraph 21 CFR173.5) for potable water applications.*
  • Uniform particle size, low pressure drop
  • Superior physical stability
  • Low color throw (APHA No. 50 Max. as shipped)

* For potable water applications, the resin must be properly pre-treated, usually by multiple exhaustion and regeneration cycles, to insure compliance with extractable levels.

 
1132 - ProSoft Gold Pressure Graph
 
PRESSURE DROP — The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at various temperatures.
 
1132 - ProSoft Gold Backwash Graph
 
BACKWASH — After each cycle the resin bed should be backwashed at a rate that expands the bed 50 percent. This will remove any foreign matter and reclassify the bed. The graph above shows the expansion characteristics of ProSoft™ Gold in the sodium form.
