To maintain a continuous flow of clean, soft water in your commercial business or industrial facility, it’s important to check that you have the correct size water softener. Water softeners vary in size and depending on a number of factors, your water softener may be too big or too small for the commercial business you’re running. Having the wrong water softener size can lead to various issues with inefficiency, frequent servicing and more that can end up costing money and resources in the long run. That is why it is critical for you to take water softener sizing into consideration to ensure your water treatment system is fully optimized for your business. Whether it’s during a routine maintenance check or while you’re considering purchasing a water softener system, be sure to do your research or ask your water softener specialist about commercial water softener sizing.

What Size Water Softener?

There are several factors that play into determining the proper water softener size and certain criteria may apply on a case-by-case basis. However, the following are the general key factors to consider in finding out what size water softener your commercial business should implement.

Flow rate (Gallons Per Day)Flow rate refers to the possibility of how quickly water will need to travel throughout your facility and during peak times.
Water Hardness (Grains Per Gallon)Water hardness is the measurement of calcium and magnesium found in the water supply in grains per gallon.
Total GPD (Grains Per Day)Total GPD refers to the daily softening requirement measured in grains per day.
VolumeHow much water per day at peak times.

We use these factors to figure out water softener size with a simple equation:

Flow Rate × Water Hardness = Total GPD

The Total GPD will allow you to determine what size water softener is needed based on the water softener system’s grain capacity. Keep in mind, this is an estimated calculation. You should consult a water softener expert when looking into water softener sizing for your commercial business or industrial plant.
