RO Water System Ensures Removal Of Many Contaminants
By James J Dixon
A reverse osmosis water filter, or RO water system,
can be an effective filtration device. The process uses
pressure to force water through a membrane that retains
contaminants on one side of the filter and allows the
treated water to pass through to the other side.
This process is more widely known for removing salt
from sea water to get fresh water, also called desalination.
RO is also used to purify fresh water for medical and
industrial processes. Let’s take a closer look
at the stages of RO filtration, to allow you to review
your options and give you an idea of whether it is right
for your home.
A sediment pre-filter is used to extract larger contaminants
like dirt, sand, dust, grit and rust particles from
the water when present. An optional secondary carbon
pre-filter is used to extract most of the organic chemicals
and chlorine; providing enhanced taste and reduction
of odor while helping to protect the reverse osmosis
membrane, which can be vulnerable to chlorine.
Disinfecting The Water With Ultraviolet Light(UV-C)
A RO membrane is normally made from a thin film composite.
An optional carbon post-filter is used to capture any
chemicals that are still present. This step also helps
guard against any tainting which might occur within
the device’s water storage tank.
Another option, an ultraviolet light (UV-C), is incorporated
into the process to disinfect the water of any organisms
that may have escaped the reverse osmosis membrane.
A RO water system can be bulky, which means it will
take up a lot of cabinet space under or near the sink.
Here are a few other shortcomings of reverse osmosis
water filtering systems.
Require A Professional Plumbing Service For Installation
Unlike faucet, countertop or carafe filters, reverse
osmosis filters require plumbing modifications and need
to be installed by a professional. If you don’t mind
modifying your plumbing and giving up some cabinet space,
then a RO filtering system may be the perfect choice
for you.
A reverse osmosis water treatment system must occasionally
be sanitized with chlorine, a chemical that is highly
undesirable and which in many cases is filtered out
by other systems.
Though chlorine is nearly universally used by city
and municipal water systems, it has been shown to cause
cancer. Using it to clean the filter that you will use
to filter out such things seems to be counter intuitive.
Flushes Away Three To Four Gallons Of Water
A RO water system may not be appropriate for everyone,
since by its very nature it is a wasteful process; it
flushes away three to four gallons of water for every
one gallon of clean water that passes through.
If your water has a poor taste or smell to it, then
you could consider a carbon-based, multi-stage filtering
system that incorporates reverse osmosis into the process.
Whether you choose a reverse osmosis system or a system
that incorporates several types of filters into one
unit, do your research before you buy; water filtering
systems can be very expensive.

Little Known Water Filtration Facts.....
Modern conveniences are great. It was a big deal twenty
years ago to be able to buy bottled water. Many older
generations were appalled at the thought though. Who
would pay for a bottle of water when it was free from
the tap?
But that was before people began to worry about the
contaminants in their water such as lead and zinc. Things
that modern water filtration systems now remove. People
truly wanted to be drinking healthier water and so these
filtration systems became popular as the reality of
what plastic does to landfills sank in.
