Hard water is not hazardous to our health. In fact, hard drinking water generally contributes a small amount toward total calcium and magnesium that a human dietary needs. In instances that dissolved calcium and magnesium were very high, water could be primary contributor of calcium and magnesium to the diet.
But not everybody knows that it must be softened. Majority of the households might wonder why clothes washed in hard water often look dingy and feel harsh and scratchy. Yes, this is due to the hard minerals combined with some soils to form insoluble salts, taking them difficult to remove. Thus, continuous laundering in hard water can damage fibers and shorten the life of clothes by up to 40 percent.
Not only has that, bathing with soap in hard water left a film of sticky soap curd on the skin and in washing dishes, especially in a dishwasher, hard water may cause spotting and filming on your crockery. And these definitely posed a serious problem to each and every household.
Hence, it would be ideal solution to leave the calcium in the water, but alter its state so that it couldn't form lime scale. And definitely, the solution is either to filter the water by distillation or reverse osmosis to remove the calcium and magnesium, or to use a water softener. Filtration is definitely expensive to use for all the water usage in a house and therefore a water softener is the most affordable solution that every household has to consider.
So what can water softener do? The idea on how a water softener works is really simple. Sodium ions will replace the calcium and magnesium ions and the problems on hard water is eliminated because sodium does not precipitate out in pipes or react badly with soap. Thus, to do the replacement, the water in the house shall run through a bed of small plastic beads or a chemical matrix.
Soft water is definitely safe for drinking because softened water still contains all the natural minerals that each and everyone needs. It’s only the calcium and magnesium ions which were taken off and some sodium is added during the softening process. It is likewise advisable that softened water contains only up to 300mg/L of sodium. Thus in areas with extreme hardness the softened water must not be used for the preparation of baby-milk, because high sodium content after the softening process has been carried out.
