A water softener system is a unit that is used
to soften water, by removing the minerals that
cause the water to be hard.
Water softening is an important process, because
the hardness of water in different applications
is reduced during this process.
When water is hard, it can clog pipes, damage
boilers, heat exchangers, and many other
devices. Water softening can prevent these
Hard water causes a higher risk of lime scale
deposits in industrial, commercial and household
water systems. Due to this lime scale build-up,
pipes are blocked and the efficiency of hot
boilers and tanks is reduced. This increases the
cost of domestic water heating by about fifteen
to twenty percent.
Another negative effect of lime scale is that it
has damaging effects on household machinery,
such as laundry machines.
Water softening using CWG water softener
system expands the life span of each household
machine, such as laundry machines, and the life
span of pipelines. It also contributes to the
improved working, and longer lifespan of solar
heating systems, air conditioning units and many
other water-based applications.
What do water softeners
Industrial water softeners are specific ion
exchangers that are designed to remove ions,
which are positively charged.
Softeners mainly remove calcium (Ca2+) and
magnesium (Mg2+) ions. Calcium and magnesium are
often referred to as 'hardness minerals'.
Softeners are sometimes even applied to
remove iron. The softening devices are able to
remove up to five milligrams per liter (5 mg/L)
of dissolved iron.
Softeners can operate automatic,
semi-automatic, or manual. Each type is rated on
the amount of hardness it can remove before
regeneration is necessary.
Commercial water softeners collect hardness
minerals within its conditioning tank and from
time to time flushes them away to drain.
Ion exchangers are often used for water
softening. When an ion exchanger is applied for
water softening, it will replace the calcium and
magnesium ions in the water with other ions, for
instance sodium or potassium. The exchanger ions
are added to the ion exchanger reservoir as
sodium and potassium salts (NaCl and KCl).
How long does a water
A good water softener system will
last many years. Water softeners that were
supplied in the 1980's may still work, and many
need little maintenance, besides filling them
with salt occasionally.
For water softening, three types of salt are
- Rock salt
- Solar salt
- Evaporated salt
How often should one
add salt to a softener?
Salt is usually added to the reservoir during
regeneration of the softener. The more often a
softener is regenerated, the more often salt
needs to be added.
Usually water softeners are checked twice a
month. To guarantee a satisfactory production of
soft water, the salt level should be kept at
least half-full at all times.
