How do you size water softener?

Best Answer

Water softeners are sized by considering several factors: the peak flow rate (gallons per minute), Plumbing size in the building, the hardness (measured in grain of hardness per gallon) of the incoming water, and peak daily water usage.

If the diameter of the cylinder is too large, a phenomenon called channelling may occur which causes the water softener to malfunction. If the diameter of the cylinder is too small, the flow rate through the softener can be restricted which can cause an excessive pressure drop across the system.

The overall capacity required (in grains) is determined by the required amount of water to be treated between regeneration cycles (in gallons) times the hardness of the feed water (in grains per gallon).

If the overall capacity of the water softener is too small, the system will regenerate too often. In a single tank unit, insufficient capacity can cause the softener to regenerate at the wrong time of day, which will either bypass the unit or cut off the product water supply, depending on the model. In a dual alternating unit, this problem is eliminated by having one tank in service while the other is regenerating. However, operating costs can be much higher for a unit that is too small for the application.

If the overall capacity is too large, the system will be needlessly expensive.

Additional factors such as chlorine or iron in your feed water can significantly affect the system that you should choose. It is generally best to consult an experienced water treatment professional to determine the correct system for your application.

What is the difference between commercial water softeners and water softeners?

Commercial Water Softeners are designed for extensive use and minimal repair. A water softener is designed to remove Calcium, Magnesium, minimal to moderate iron, and manganese out of water. Commercial Water Softeners are designed for easy repair. They are more expensive, but very simple when it comes to pulling motors, changing valves, and replacing switch boards. A "water softener" that you buy off the shelf or from a dealer is a softener that is designed to take far less load, or "burden", and thus it often needs replacing. The word I am looking for in a Commercial Water Softener is "serviceable". Commercial water softeners are made to be serviced and work year after year. Yes you can service consumer grade softeners but they are not designed to be serviceable - or we would all service our own. The Softener Industry designs Commercial Softeners so they are easy for the them to service, but still bill-able to you. When pulling a consumer grade softener apart you find - bearings and wheels. But if you take the face off commercial models - the motor comes out easily (just unplug it) - the valve takes a little more time, but replacing the computer board is as easy as unplugging the wires. For Residential use - a commercial water softener is a minimal repair softener system, with prolonged life. If you are using a commercial water softener for commercial purposes - because of industrial use, it will need scheduled services. When compared to consumer grade softeners - commercial water softeners are excellent performers.
