| Water Softeners
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 negative effects.
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 Pure Aqua 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 do?
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 softener last?
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.
Softening salts
For water softening, three types of salt are generally
sold:
- 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.
