DECALCIFICATION OF WATER: What is Meant by Decalcification of Water and How is it Done?

You would have often heard the term ‘hard water’ or ‘calcified water’ and might have experienced its harmful effects as well. Hard water is the water that is enriched with chlorides, bicarbonates and sulfates of calcium and magnesium ions. Such water is unacceptable to be used for different chores and hence, needs to be decalcified. Let’s take a look at this process and understand how it is done.

What Does ‘Decalcification of Water’ Refer To?

Decalcification of water refers to the process in which the positive magnesium and calcium ions and their salts are removed from water. Whenever these ions enter water, they combine with the carbon dioxide present in water and create ‘calcium hydrogencarbonate’ that results in the production of an unpleasant white colored scum in the water. This scum is often referred to as ‘scale.’

This scale is a major threat to common household and industrial chores. It prevents you from drinking water, bathing, cleaning, washing and laundering. Moreover, it starts building up in pipes and damages them. This disrupts the industrial processes and results in numerous problems.

Hence, to avert all these troubles, it is very important to get rid of the troublesome calcium and magnesium ion. With the help of decalcification of water, these cations and their salts are eliminated from water and all related issues are resolved.

Understanding the Process of Decalcification of Water

Decalcification of water is done in a number of ways. The main aim of this process is to take out calcium and magnesium ions from water, so they do not form scale. This goal is achieved by using a water softener. Different water softeners employ different techniques for getting rid of these ions.

One commonly practiced technique of removing these ions is by using the ‘ion exchange’ process. In this process, different salts are added to the mineral tank of the water softener, and when hard water passes through this tank, the positive ions of the salt replace the magnesium and calcium ions. For example, if you are using sodium chloride pellets, then the sodium ions will take over the magnesium and calcium ions, hence, the hard water will no longer remain hard.

Besides, sodium chloride, potassium chloride can also be used.

Apart from the ‘ion exchange’ water softeners, there are magnetic and electronic water softeners in the market. They are also known as ‘salt-free’ softeners. In these softeners, nano technology is exercised for the decalcification of water. These softeners alter the entire structure of these ions, making them incapable of forming scale.

Which Softener Should You Get for Decalcification of Water

If you are looking to buy a water softener for your home, then it will be wise to purchase an ion exchange softener as it consumes less energy and is effective too. However, if you want one for your factory, then it is better to invest in a fine quality electromagnetic or electronic softener as they are faster and more efficient, hence suitable for factories.
