Why Hard Water Could Be a Hidden Danger to Your Home? Discover the Secrets of Water!
Hard water is common in many homes, but are you aware of the hidden dangers it can cause? Minerals such as calcium and magnesium contained in hard water not only affect the quality of life, but may also pose a potential threat to the home's plumbing system and personal health.
What problems does hard water cause?
Hard water is high in metal cations such as calcium and magnesium, which can cause a variety of problems. First, hard water can cause scale to form, which not only affects the service life of water pipes, but can also promote electrochemical corrosion and affect the home's plumbing system.
The accumulation of scale will make the pipes narrow, affect the water flow rate, and even cause blockage of the pipes.
Secondly, soap is less effective when washing with hard water. This is because the calcium and magnesium ions in hard water react with the ingredients in soap to form precipitates that are difficult to dissolve, which is why soap residue is often found in bathtubs and showers.
How to improve water quality?
One way to improve hard water is to use a water softener. These devices can effectively remove calcium, magnesium and other ions from water. The most common water softening methods include ion exchange and reverse osmosis technologies.
A water softener uses sodium or potassium to replace calcium and magnesium in the water, thereby reducing scale formation.
Also, there are other methods such as adding chemicals like washing soda, while distillation and rainwater harvesting are two non-chemical water softening techniques.
While the sodium content of water increases during the water softening process, it does not usually cause a significant impact on most people's daily health. According to research, even if the sodium content in daily drinking water is about 278 mg/L, this only accounts for 22% of the daily sodium intake recommended by the Centers for Disease Control and Prevention.
However, for those who need to limit their sodium intake, special attention should be paid to the quality of the water they drink.
In addition, the high hardness of hard water is often associated with the early development of skin conditions such as eczema, but further research is needed to determine the cause and effect relationship between them.
Environmental impact
Hard water treatment can also have environmental impacts, particularly in agricultural irrigation. Softened water may lead to the formation of alkaline soils due to its higher sodium content.
Therefore, caution should be exercised when using water produced by traditional water softeners for irrigation.
Several non-chemical devices have been proposed as alternatives to traditional water softeners to address water quality issues in a more environmentally friendly manner.
