Hard Water Vs. Soft Water

December 7, 2016

We often talk about the hard water and soft water in our daily life. Hard water may cause scale building up in the home appliances while soft water will improve the experience of water use, especially when taking shower and washing faces. As a result, many people prefer soft water and often use some water treatment devices to treat the water. Such devices are more needed for the residents in the old lane compounds like French concession where the aged pipes account for most of the hard water issues.



What causes hardness in water?

The chemical difference between the two types of water basically comes from the mineral content. Hard water contains a large amount of these dissolved minerals, such as magnesium, iron, and calcium. Having never experienced soft water, it is often difficult to appreciate a difference, but many people who have installed water softeners and made the switch swear by the superior nature of soft water.



Effects of Hard Water

Though lack of solid proof, hard water is suspected to link to some adverse effect to human like cardiovascular diseases and lithiasis. Hair washed in hard water can feel sticky and look dull. Studies also suggest that hard water can cause an increase in eczema in children. Aside from the health effects hard water can also cause many inconveniences to our life. It can leave spots and film on dishes and bathtubs and be more damaging to household appliances. It can leave deposits, called “scale,” that clog plumbing and impair the flow of heat in boilers, leading to overheating.




Why soft water

Soft water contains little to no magnesium and calcium. It actually feels soft on your skin and may even have a silky, almost slimy texture. While this can make it soothing to bathe in, it can also leave your skin and hair feeling like there is a film left over. When soft water is used to wash hair, it will greatly reduce the use of shampoo and shower gel as very little shampoo will generate lots of bubbles.



How to soften water

Hard water can be “softened” by reducing the concentration of calcium, magnesium and other minerals. Temporary hardness of water can be treated either by boiling it or by adding lime (calcium hydroxide). Permanent hardness of water can also be treated with water softener composed of ion-exchange resins and salt in which hardness ions are exchanged for sodium ions.
