The so-called “hard water” is defined as water with high mineral content, which is formed when it passes through chalk and limestone deposits that consist of calcium and magnesium carbonates.
There are some health benefits from drinking hard water. However, this type can bring about critical problems when used in industrial settings. Water hardness should be monitored when it comes to such environments, in order to prevent costly breakdowns in related equipment – like boilers and cooling towers.
When it comes to households, it is easy to see if there is hard water. Limescale is formed in kettles and heaters, or no foam is formed when soap is combined with water. The end users can resort to softening to minimize the adverse effects given by hard water. Before looking into this process, they should know more about soft water. So here follows:
Soft Water Facts
It refers to water with low concentrations of ions, specifically calcium and magnesium ions. Soft water happens naturally where the rivers’ drainage basin is formed of hard, impenetrable, calcium-deficient rocks. An example of such place is Western Highlands in Scotland.
To others, soft water is the type of water produced by means of a softening process.
This is not that accurate though, since the correct term for this type is actually softened water. High levels of sodium and bicarbonate ions may be present in softened type in such cases.
There is no soap scum formed when washing with soft water, and this happens because it only has few calcium ions.
Also, soap can easily lather when mixed with water. Just the same, there will be no calcium deposits produced in the heating systems. There are only two types of water, so if it is not soft, it is hard.
The water is considered soft when it follows the requirements of a particular state or country of residence. In the United Kingdom, as an example, if the water hardness is below 50 mg / l of calcium carbonate, it is regarded as soft. If it is above this number, then it is considered hard.
When it comes to the US, water is classified as soft when it has below 60 mg / l of calcium carbonate. The majority of US states have hard water because of the ancient sea beds with high concentrations of limestone. That is why the people here want a softening treatment for their water.
