What are water softeners?
The water softener is a device that softens water by removing calcium and magnesium contained in hard water through the exchange of positively-charged ions in the resin. Scale (crystallization of minerals) resulting from continuous use of hard water can build up in water heaters, dish washers, washing machines, and pluming, impairing the efficiency of such products and lessening their product life.
With soft water, however, scale build-up will not occur, and damage to the above products will be minimal, making it possible to significantly cut costs in various ways.
Benefits of water softeners
<Shower and bath>
Washing your body with soft water makes your skin smoother and more supple than with hard water.
Soap and shampoo lather better, with enhanced cleansing power.
<Skin and hair>
After washing your face with soft water, your skin is left feeling supple without being stiff.
Doing housework with soft water helps prevent dry and chapped hands.
Soft water helps reduce dryness and dehydration of skin after a bath.
Soft water makes it easier to shave one’s face, minimizing razor burn such as skin rash.
Soap and shampoo lather better in soft water, preventing itchiness of scalp and dryness of hair for increased glossiness.
<Cleaning (dishes, kitchens, toilets, bathrooms)>
Soap and shampoo lather better in soft water, with enhanced cleansing power.
With soft water, only small amounts of detergent will be needed to wash dishes. Dishes will be sparkly clean.
White flakes (scale resulting from hardness of water) will not form in kettles or water pots.
Soft water extends the life of electric water pots and rice cookers.
Soft water helps prevent the build-up of water stains and hot water scale on kitchen faucets and sinks.
It will be relatively effortless to clean bathtubs, washbasins, and toilets since they do not get as dirty.
Soft water helps deter the formation of mineral residues (soap scum), thus substantially boosting the cleansing power of detergent. As a result, clothes will come out cleaner and whiter, with less yellowish tinge. It is more economical to use soft water because less detergent will be needed to do laundry.
(Mineral residues, or water-insoluble soap scum, are formed when soap bonds with calcium and magnesium present in tap water.)
What is ion exchange?
When mineral-laden water passes through the ion exchange resin, minerals that account for hardness of water (positive ions) such as calcium and magnesium ions will attach themselves to the resin, replacing sodium ions contained in the resin in the process. This is a chemical reaction called ion exchange, in which hard water is converted to soft water. Continuous treatment of hard water will eventually lead to saturation of the resin with “hardness” minerals, causing a decline in ion exchange activity. Consequently, the resin’s water softening ability will be diminished. However, by injecting salt (NaCl) water into the ion exchange resin, sodium (Na) ions contained in salt water will replace the calcium and magnesium ions that have accumulated in the resin, thereby restoring the resin’s water softening capability. (The “hardness” minerals will be discharged in the process). This is called regeneration of resin. By repeating this process, hard water can be continuously converted to soft water.
What kind of maintenance is required?
Since our products are automatically operated, maintenance is very easy. All you have to do is to add salt to the tank once a month (the frequency may vary depending on usage). Then, the automatic timer for measuring water usage will start the regeneration process by circulating sodium solution (salt water). Repetition of this operation ensures constant, steady supply of soft water.
