SOFT WATER AND HARD WATER
- What is a water softener?
A device that supplies soft water by using ion exchange resin to absorb and remove the main
cation ingredients in hard water, including calcium, magnesium, iron and manganese. These
hard water ingredients have a negative effect in our lives as they cause skin problems, lower
washing efficiency, abrade fibers, corrode pipes and generate slime. When ion exchange resin
becomes saturated, it can no longer absorb and remove these ingredients. However, you can
use it semipermanently by repeated regenerations using sodium chloride solution (NaCl).
Skin problems
Lower washing efficiency
Fiber abrasion
Pipe corrosion
Slime
Soft and hard water refer to the degree of softness of the water. Soft water refers to water that is soft while hard
water refers to water that is hard.
* Water supplied to each household has a certain degree of softness as well as the water source (whether it is
underground water or running water). Underground water from areas with more limestone strata contains
more calcium. Therefore, it is considered as hard water too. Calcium, magnesium, iron, silica, etc. are dissolved
in water inside the earth and make the water hard. While underground water in areas with more limestone
strata contains calcium and is hard.
■
Rain and snow are originally soft water. While soaking into the earth, it becomes hard water as
it dissolves all kind of minerals, particularly calcium and magnesium. Water from wells or
underground has very high hardness as it contains high mineral content.
■
White powder appears on the walls, floor or kettle surface while boiling hard water. The main
ingredients in this powder are concentrated and solidified hard water components, which are the
same as those remaining on washbasins, baths or taps.
■
An easy way to compare soft and hard water is by using soap but soap dissolves well in soft water
and cleans less effectively without feeling smooth, but soft water dissolves well even if you use a
small amount and feels smooth after washing/cleansing.

This Coway water softener removes hard water components from water source to make soft water.
- This Coway water softener removes hard water components from source water using ion exchange resin to make soft water.
- Regeneration refers to the restoration of the performance of the ion exchange resin, which weakens after it has
absorbed a lot of hard water ingredients, and is an important process in restoring the softener’s performance.
