How Soft Water and Hard Water Behave Differently

Hard & Soft Water

Some people think that all water is the same regardless of where it comes from. The truth is that water quality varies widely throughout the country. Some water may be deemed ‘hard’ or ‘soft,’ and that can have a significant impact on your daily life. Read on and discover the difference between hard and soft water.

Hard vs. Soft Water

According to the U.S. Geological Survey, 85 percent of water in the United States is “hard,” meaning it contains high amounts of calcium and magnesium because it comes in contact with rock and soil. Soft water, on the other hand, contains relatively few elements, and in some cases none at all. Soft water can occur naturally or be produced with treatment devices that reduce elements of water hardness.

Bathing

Certain minerals in hard water make soap and other cleaning products less effective, hampering their ability to properly lather. Hard water also creates soap and buildup in the showers, requiring more intense cleaning effort and increased use of chemicals to clean the bath.  Soap lathers easily when you have soft water, meaning you can use less (and save money on personal hygiene products), plus you won’t have to spend all your free time scrubbing hard water stains from your bath fixtures.

Cleaning

Similar to your bath soap, minerals in hard water interact with detergents that you use to clean your home and your laundry. This impacts its ability to clean dirt and stains, and requires that you use more detergent to clean your clothing. With no minerals to interact with your detergents, soft water can decrease the need for detergent by up to 50 percent.

Energy Usage

Gas water heaters using only hard water will consume more energy than those that use soft water, lowering the system’s energy efficiency and increasing water heating costs. In addition hard water residue can build up in a water heater over time and lead to deterioration sooner than if you had soft water. Soft water cuts overall energy cost and helps preserve the life of your home appliances.

Pipes and Stains

Hard water can cause buildup in pipes and the heater, which impedes water flow and can eventually block the pipes entirely, leading to potential flooding and/or expensive pipe replacements. It can also cause your small appliances around the house to deteriorate faster, such as your dishwasher and washing machine. In the long run it will cost you a lot more to pay to replace these things more often than if you paid for water softening technology.

A water softener removes the calcium and magnesium from the water and will protect your appliances, reduce cleaning time, and will help skin and hair to be softer and less dry.  A Kinetico water softener also uses no electricity, uses 70% less salt and will provide a couple of decades or reliable, trouble free service.

Kinetico’s Hard Water Vs. Soft Water Science Project Idea

Kinetico Utah - Soft Water Science Project Idea Utah

Have you ever wondered about the science behind a water softener? At Kinetico of Utah we are education advocates and love to have fun while learning! Here is a great way for you and your family to get an inside peek at some of the science behind soft water. The first thing that you will need to have is our Kinetico Utah Water Softener Words and Definitions list.

Water Softener Words and Definitions List

Soft water – water that is free from hard minerals like magnesium and calcium.

Hard water – water that contains magnesium, calcium.

Calcium – a silver-white metal found in limestone and chalk.

Epsom salt – a type of Magnesium.

Ion Exchange-the process of reciprocal transfer of ions between a solution and a resin.

Magnesium– a light silver-white metal used in lightweight alloys, flares, and fireworks.

Salt – a crytalline compound called sodium chloride. An element that gives liveliness and is also a preservative.

Soap – a substance usually made by treating a fat with alkali, as sodium or potassium hydroxide.

Distilled water – water from which impurities have been removed such as; dissolved salts and colloidal particles; chemically pure water.

Now that you have read and understand each of the above water softener words we will get started! We are going to start with an easy science project that we found on scifun.org that you can do at home with your family. Get ready to experience some of the science behind Hard water vs. Soft Water.

You will need:

Distilled water  (2 cups)

Epsom salts (1 Tsp)

2-liter plastic soda pop containers, with screw caps. (2 containers)

Liquid dish soap (do not use soap intended for dishwashers) (several drops)

Instructions:

1. Empty and clean the 2-liter plastic containers (on 1 bottle use a sharpie and write Hard and on the other container mark it Soft)

2. Pour (1 cup) of distilled water into each of the empty soda-pop containers.

3. Add (1 teaspoon) of Epsom salts only to the bottle marked Hard.

4.   Swirl the bottle until the Epsom salts dissolve.

5.   Add several drops of liquid dish soap to both bottles.

6.   Seal the bottles with their caps.

7.   Shake both bottles.

After following the instructions you will see two different results!

The bottle marked Hard represents hard water. In this experiment, you created hard water by adding a small amount of Epsom salt to distilled water. Hard water is found in your home before it is treated with a water softening system. Calcium and magnesium in water interfere with the cleaning action of soap and detergent by creating a barrier (soap scum). If you have hard water in your home you will use about 50-80% more soaps and detergents to get things clean! Hard water has a hard time creating bubbles, and that means your laundry doesn’t get as clean and you will be taking more expensive bubble baths!

Look at the container marked Soft. This bottle represents Soft water and will have more bubbles! Soft water does not contain hard minerals, allowing the water to work with the soap which increases the cleaning capacity of detergents and creates more bubbles! Home water softening systems help protect plumbing and appliances by decreasing the buildup of lime scale deposits. Laundry cleaned with soft water is softer and cleaner. Bubble baths get bigger and better. A Kinetico Quality Home Water Softener saves you more time and money, time and money that you can spend on the people you love most!

How Much Salt is Added to Soft Water

man drinking water

One of the most common questions about water softeners is how much salt or sodium is added to my water. Generally it’s much less than people think. There is a very simple formula to calculate how much salt it added to the water.

Grains of hardness (gpg) x 1.89 = mg added to an 8oz glass of water. If your water is 15 grains hard you would have about 28 milligrams (mg) of added sodium in the water.

Grains per gallon (gpg) is the measurement used to calculate hardness and the scale goes as follows:

Less than 1 Grain Soft
1.0 to 3.5 Moderately Hard
3.5 to 7.0 Hard
7.0 to 10.5 Extremely Hard

If your water is 15 grains hard then you would have about 28 milligrams (mg) of added sodium in the water.

Even for people who are on a low sodium diet this amount of salt shouldn’t be a problem. Most of the sodium we eat comes from processed foods and table salt. If you compare the amount of sodium already contained in foods we think of as having low amounts of salt the amount added by a water softener is very low. As an example, an 8oz glass of milk will contain 125mg of sodium and a slice of white bread will have about 120 mg.

To find out how hard your water is contact a water softening company and they can test it for you, or contact you local city water department and they can tell you the number of grains per gallon of hardness you have in your water.

For those who don’t want to drink soft water there are a couple of solutions. The first is to install a water purifier that will remove the sodium. Reverse osmosis is the most effective method. Another option is to bypass the drinking water in the kitchen so it remains hard water.

Soft water is simply water that is free of calcium and magnesium. A water softener works by removing the hard minerals and replaces them with sodium through a process known as ion exchange.
