Industrial Water Softener Sizing Calculator

The following calculations can be used as rough guides for industrial water softener sizing. If you have a unique application, please see the specialized water softener calculators:

There are many variables in sizing industrial water softeners beyond the scope of the water softener calculator below. Water pressure, temperature, flow rate and cubic feet of resin per tank are all variables that also have effects on water softener sizing and are not considered here. These guides are to be used for quick estimates only.

For detailed industrial water softener sizing including configurations (e.g. single, twin parallel, twin alternating, triples, quad softeners), control types (timeclock, metered, PLC, progressive flow, additive flow) or pretreatment for reverse osmosis, deionization or other ultra high purity water treatment equipment, it is important that you email or call Nancrede Engineering at 888-56-WATER (569-2837). Our engineers are the same people you get in the field when there is an issue or when you call our free, unlimited technical support. Contact us right now, and we’ll find the perfect system that will save you energy and salt.


General Industrial Water Softener Sizing Guide

Average Gallons Per Day (GPD) Flow Rate:
Peak Continuous Flow Rate GPM*:
Desired Hours Between Regenerations:
Hardness of Water (Grains Per Gallon):
Capacity per Cubic foot of Resin (Grains):
 
   
Total Gallons of Water Used Per Regeneration:
Cubic Feet of Water Softener Resin Needed Per Tank:
Inch Valves (estimate):

* Peak Continuous GPM is not instantaneous peak flow rate. It represents a continuous high flow rate at peak times of the day (e.g. for 30 minutes or more).

** Instantaneous peak flow rate is the maximum GPM for a short time (e.g. 1-5 minute period).
