Water after softening is not sterile, and understanding why this is the case requires some knowledge of the water softening process. Water softening has absolutely nothing to do with water demineralization. Basically, water softening works by removing the calcium and magnesium ions that are responsible for water hardness.
Water softening is done through a process called ion exchange. This is the process by which the calcium and magnesium ions in the water are replaced by other ions, usually sodium or potassium. This happens on an ion exchange resin - a special material that has the ability to attract and retain certain ions while releasing others.
The role of pre-filtration
Prior to the softening process, the water usually passes through a pre-filter that removes large mechanical particles. In addition, the chemical composition of the filtered liquid does not change. Water after softening is not sterilized because it still contains many other minerals that are important to us.
Preparation of coffee and tea with soft water
One of the many uses of softened water is the preparation of coffee and tea. Why? Because water with a minimum degree of hardness is recommended for this type of hot drinks. When water is hard, minerals can affect the taste and quality of drinks.
Soft water allows you to fully reveal the taste of coffee and tea. Water that is too hard can obscure the delicate flavors, altering the final effect. Soft water makes drinks more expressive in taste, leaves no residue on the dishes and has a better appearance - just like those from the best coffee shop.
Sterilized softener water
Water softening is designed to improve water quality by removing certain minerals that cause water hardness. However, this process does not mean that the water after softening is sterile. Softened water is still full of other minerals that are crucial for our health and good quality drinking water.
Of course, as with everything, balance is key. Both hard and softened water have their place in our homes and our lives. It's important to understand how and when to use each for optimal benefits for our health, comfort and well-being.
