Industrial Water Softener Sizing Calculator

How do you calculate the size of an industrial water softener? See our full list of industrial water softener sizing calculators or use the general water softener size calculator below. These calculations can be used as rough guides to determine the proper industrial water softener size for your application.

If you need information about your water to complete the calculator, note that we offer free basic water testing to qualified engineers and industrial, commercial, and healthcare organizations. Note that if you looking for water softeners for healthcare facilities or hotels, please see the specialized water softener size calculators below:

General Industrial Water Softeners: Calculate the Proper Size with our 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 Between Regenerations:
Cubic Feet of Water Softener Resin Needed Per Tank:
Inch Valves (estimate):

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

For detailed industrial water softener sizes and 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 Industrial Water Solutions at 800-820-9021. Our engineers have practical experience – they 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 best industrial water softener system that will save you energy and salt.

Do you need industrial water softener repair or maintenance? Industrial Water Solutions also offers preventative maintenance, engineering consultation, and repair for industrial water softeners. We also offer industrial water softener leasing, financing, and build, own, operate options. Let us know if you would like information on how these services can help you reduce water softener downtime and capital risks.

* 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).
