Know The Best Water Purification Process

Once upon a time, the water available in
nature was pure ? free from all sorts of
contaminants and rich in all essential
minerals. But nowadays, due to a rise in
pollution, natural water has become a
rarity. The utmost need today is to use
an efficient water purification process
to get back the same purity and taste as
that of the natural water.

The water which is supplied to our homes
is full of pollutants like pesticides,
chlorine, bacteria, cysts etc. Drinking
such contaminated water is just not
right. This can lead to various
ailments.

Understanding this, we know the need of
the hour is to have a good and efficient
water purifier system which can remove
these contaminants and purify the water.
Broadly speaking, there are three types
of water purification process used in
the commonly available water purifiers:-

(i) Reverse Osmosis

Reverse osmosis water filters work by
forcing a huge amount of water to pass
through a fine semi-permeable porous
membrane. The water molecules being
smaller than the size of these pores,
rush through this membrane leaving
behind the contaminants which are larger
in size.

They are efficient in producing clean
and pollutant-free water but the basic
problem with these filters is that they
remove everything from the water- even
the essential minerals found in the
natural water. These minerals are
magnesium which helps in strengthening
the immune system; calcium which helps
in increasing the strength of teeth and
bones etc.

Consuming water which is lacking in
these minerals can cause digestive
problems and later result into mineral
deficiencies as well. Removing these
minerals from drinking water and then
taking supplements for them is not a
logical solution.

(ii) Mineral Revitalization

The water filters based on mineral
revitalization are actually one step
addition to the water purification
process used in reverse osmosis. These
filters have an extra unit attached to a
RO based water filter and are primarily
designed to take care of the problem of
RO based water filters.

First the RO filter strips out
everything from the water (the
contaminants and minerals), and then the
extra unit used in these filters,
artificially adds the minerals back into
the water.

This helps in retaining the natural
taste and odor of the water. But don?t
you think, it is a little illogical to
pay additional costs for these filters
just to get back something which you
already have. If minerals are required
in the water, why remove them in the
first place?

(iii) Ion exchange and carbon filtration

These water purifiers are generally
equipped with two filters and have two
stages processing of the water. First
stage uses ion exchange technique to
remove chlorine from the water. It also
enhances the pH balance in the water.

The second filtration stage uses carbon
filtration technique to remove all
chemical and synthetic contaminants. It
also removes all by-products of chlorine
like Trihalomethanes (THMs), Volatile
Organic Chemicals (VOC's) which are
toxic vapors and have adverse effects
even if inhaled or absorbed in the skin.

These multi stage water filters are the
best water purification process which
removes all type of organic and
synthetic impurities from the water
while retaining the essential minerals
at the same time.

Before buying a water filter, select the
water purification process which is best
for you. Whatever filter you select,
make a choice today and ensure clean and
pure drinking water.
