We are surrounded with almost 85% of water, hence it is decided that no
matter how much we fight for the absence of enough food products for all but we
can never go without getting water. There is enough of it for all of us.
Although there is a lot of water throughout the world, still we crib about the
quality of water that we generally take in. You can live without having food
for over a few months but you cannot survive without taking in water for over a
week. It is very important for us not to waste it and try to use every single
drop of water, this way we will be able to save quite a bit of it and utilize
it wisely.
Earth is enveloped with 1/3 rd. of water and the oceans, seas,
river, etc. embody most of the water. So it is better to utilize the vast
amount of water that is already available in huge amount. Many people have got
big doubt whether the sea water can get transformed into usable or rather
drinkable format. Well, yes the sea water can be easily converted into
consumable format by a process called Desalination.
It is known to all that the sea water is extremely salty in taste due to
the presence of salty particles in them. These salty substances make the water
undrinkable. In order to make this saline water drinkable, it is
important to eradicate the salty particles from the water. Desalination is a
process by means of which the salts and minerals that are generally present in
the sea water get removed. Although there are different processes of removing
salt from water, still the process of desalination is the commonly used
technique.
The process of Desalination is very useful because,
(a) The sea water can be
utilized properly.
(b) Sea water becomes an additional
source for the extraction of drinkable water.
(c) Groundwater can be prevented from
getting dried up. Otherwise we tend to use up all the underground water. It is
always better to utilize all the water that is available in the water bodies
that have got enough water rather than digging up the wells.
High pressure is required to wash off the salty particles out of the
water through a substance. This substance should be a semi-permeable membrane
(say plastic) that allows the liquid to pass through it. When the water gets
passed through the plastic membrane, the salt particles that are left behind
form the residue. This process is also known as reverse osmosis.
The water plants that are designed to provide mineral water to the society also converts the saline water into drinkable water by means of
reverse osmosis.
