All the Different Methods of Water Softening Explained

Imagining life without water is impossible. We all perform different daily chores with water like laundry, washing utensils, bathing, cleaning, and drinking. If water is impure it needs to be purified. Water hardening is due to two components: Calcium (Ca) and Magnesium (Mg) due to which all the household tasks become difficult. If you are looking for different methods to soften hard water, this guide will help you in the same.

Before we jump to water softening methods, let’s take a quick look at what hard and soft water is?

Hard & Soft Water:

Hard water is when it contains a large number of minerals in it.  Calcium carbonate, magnesium, manganese, and iron are a few minerals that tend to water hardening.

Hard water creates troubles in everyday chores. Scaling, laundry stiffness, white films on utensils, boilers, heaters, and clogging of pipes are some issues. Cleaning becomes difficult with hard water. Water consumption increases as detergents do not get washed quickly. Taste different, leave spots on surface and tiles. Hard water decreases the life span of the machinery.

Soft water contains a minimal amount of minerals or one must say the correct amount of Ca and Mg that is healthy. The major source of soft water is rainwater.

Water Softening:

A process by which hard water can be converted into soft water by eliminating calcium and magnesium from water is known as water softening. You can DIY a water softening process at home. For that, you can go through the following methods that can be executed at home. If you are looking for water softeners, check “here” to know how to choose one for your home.

Different Methods of Water Softening:

  • Ion Exchange Water Softening: The most common and efficient method of water softening is an ion exchange method. It involves the exchange of minerals (Ca & Mg) through sodium ions.

The sodium ions come from brine solution which performs a rigorous process for water softening.


  • Distillation Method:  The water is heated inside a container until evaporation starts. The evaporated water is fed through a cooling tube to store in a tank. Vapors condense and transform into a liquid state. The water is soft pure water with no impurities (minerals).

This method is cheap and can be executed easily at home. However the quantity of water is very low, that is good for drinking purpose.

This water should not be consumed on a daily basis as it lacks essential minerals needed for the body. (For office water coolers, alkaline filters can be installed to re-mineralize water)

  • Reverse Osmosis (RO): Reverse Osmosis is a process to push water through extremely fine filters under pressure of 35 psi for filtering impurities and attain water pH balance. Hard water containing minerals, chemicals or organic dissolved solids all gets removed in this water softening process. The impurities flow out through drainage pipe and soft water is stored in the water coolers.

  • Chelation (Water Conditioning):  Chelation means conditioning water hardening ions and chemicals that contribute to lime scaling. It is an illustrious process for descaling limescale making water fitting for household use.

This process is environmentally friendly as no water or electricity wastage is there. No sodium and negligible maintenance make it affordable and handy.


Water softening is an essential task when you live in an area where hard water is the only alternative. It helps you eliminate complications and excessive minerals consumption.
