http://www.isopurewater.com/Water-Softeners_c_937.htmlMany people confuse water
softeners as a form of water filtration. Water softeners exchange calcium
and magnesium ions for other salt ions like sodium or potassium. Calcium and magnesium ions create something
called “hard water” and it is not aesthetically pleasing to the eye. People
will find white spots on the glass or a hard thick white lime build up on the
faucet. This can cause problems for the home with the pipes, showers, and
appliances like the dish washer or coffee machine. Water softeners can stop and reverse the
effects of scale build up.
filtration systems are systems that remove contaminants or particulates
such as carbon filtration, sediment filtration, iron filtration and so on. The most common question I hear is “can my
water softener be used to remove Chlorine?”
The answer is no, it can’t do anything other than exchange ions to
create soft water. Water filter systems
help improve the actual water quality and typically fix things that typically
cannot be seen by the naked eye like chlorine, pesticides/herbicides, or
Water filtration systems are best used as a pre-filtration
to any softener to not only extend the life of the softener but to give your
home a full range of filtration and water conditioning. Water filtration systems like a carbon filter
will extend the life of a softener’s resin by removing the chlorine in the
water. Chlorine can easily damage and breakdown the softener’s resin which
reduces the life of the softener and will cause you to change out resin earlier
Iron tends to work too well on softener resin and can “foul”
the resin quickly and there for it needs to be removed before it enters a water
softener. Levels higher than 0.3 ppm
recommend having the iron filter in order to prevent fouling. Iron water filter systems using Filox/Pyrolox,
Birm, or Greensand are a must as a pre-filter for a softener.
A very standard setup is using a carbon filter with a water
softener on a home with city tap water.
Homes with well water may need extra filtration with an iron filter if
the iron levels in the water are over 0.3 ppm of iron. It’s always best to check your iron levels
before installing any system in the home. If you have any questions, always
call a professional for some advice before purchasing any unit.
