Commercial & Industrial Water Softeners

Mueller Water offers two premier water softening systems tailored to meet diverse application needs: the Fiberglass (Series WSF) and Steel (Series WSS).

The Series WSF is ideal for commercial environments where corrosion resistance and low maintenance are critical. Its lightweight, non-corrosive fiberglass design ensures long-term durability and easy installation, making it perfect for areas with aggressive water conditions. Common applications include restaurants, schools, office buildings, hotels, light manufacturing, and multifamily settings.

The Series WSS, crafted from durable steel, is built to withstand high pressures and demanding industrial conditions. With protective coatings for enhanced corrosion resistance, this system is the go-to choice for heavy-duty applications in laundries, healthcare facilities, hospitality, power plants, and manufacturing environments.

Water softening prevents scale buildup, enhances cleaning efficiency, prolongs equipment life, and improves overall water quality. Choose the water softener that best suits your environment and operational needs, and ensure your system's longevity with Mueller's trusted expertise.

Frequently Asked Questions

How do you size a commercial water softener?
Sizing a softener depends on water hardness and daily water use. (1) Measure hardness in grains per gallon (gpg); divide ppm by 17.1 to convert. Across much of Texas, hardness runs 15–25+ gpg. (2) Add about 4 gpg of compensated hardness for every 1 ppm of dissolved iron. (3) Estimate daily water use (about 75 gallons per person per day for domestic use, or use metered data for commercial). (4) Multiply compensated hardness by gallons per day to get the daily grain load. (5) Size resin volume so the unit regenerates every 3–7 days; use twin-alternating tanks for continuous commercial demand. (6) Verify the rated service flow (gpm) meets peak demand.
What is the difference between fiberglass and steel water softeners?
Fiberglass softeners (Mueller Series WSF) are corrosion-resistant, lightweight, and low-maintenance — ideal for restaurants, schools, office buildings, hotels, light manufacturing, and multifamily settings. Steel softeners (Mueller Series WSS) handle higher pressures and demanding industrial conditions with protective coatings for corrosion resistance — used in laundries, healthcare facilities, hospitality, power plants, and manufacturing.
How hard is water in Texas?
Across much of Texas, water hardness runs 15–25+ grains per gallon (gpg), classified as "very hard" by US Geological Survey standards. The Edwards Aquifer supplying San Antonio is among the hardest in the state. Hardness this high requires correctly sized softening to protect plumbing, boilers, cooling towers, and process equipment from scale.
How often should a commercial water softener regenerate?
A properly sized commercial softener should regenerate every 3 to 7 days. More frequent regeneration wastes salt and water; less frequent regeneration risks hardness breakthrough. Continuous-demand applications should use twin-alternating tanks so soft water is always available during regeneration.
