Water Filtering and
Purifying Systems
Water purification
methods range from simple filtering at the tap to reverse osmosis,
distillation, ionization, ultraviolet radiation, and other, more complex
methods employed by municipal water treatment plants.
A water filtering system may use a salt
water filter or a carbon water filter or a combination of these in
conjunction with various other methods of water purification. You may
want to keep it simple and just filter your drinking water at the
kitchen faucet. On the other hand, you might want to explore ways to
further purify your water.
First, whether you are on city water or private well water, have your
water tested professionally. Obtain a report detailing exactly what is
in your water. This way you can choose a water filtering system that is
best for removing the specific types of contaminants in your water. You
may do the research yourself or consult with a professional water expert
for a recommendation.
In reverse osmosis (RO), a very fine membrane that is only 0.0001 micron
per hole removes everything from the water. This system, also called
ultra-filtration, was originally developed by the government to
desalinate sea water. In the household, it is usually installed under
the sink. It often requires professional maintenance, as a technician
may need to periodically check to see if the membrane needs replacing.
Ionized water filters use positive and negative electrodes to split the
water into two types of water: alkaline and acidic. Alkaline ionized
water is used for cooking and drinking, while acidic ionized water is
used on the skin for bathing. Acidic ionized water kills many different
types of bacteria, including E. Coli. Some people report health benefits
from using ionized water.
A magnetic water filtering system passes the water through a magnetic
field to condition it. This method is controversial, as it does
rearrange the ions but the effect is not permanent. This system is
typically installed where the water enters the house. The system is
based on the work of Viktor Schauberger, a water researcher. It softens
hard water but does not filter out minerals.
