The use of water for medical purposes
The water
which is free of gems is used for medical purposes. This water is carefully
purified. Usually there are two ways to clean water. In the first method water
is passed through a very thin filter paper. Like this the harmful germs remain
in the paper. And in the second it is kept in a tank for some time. During this
water is continuously heated. Like this the germs in water die. That distilled
water is mostly used in syringes. Apart from that, this water is used to make
medicine solutions. Which are inserted in skin through syringes. In the distilled
water which is provided to hospitals, they mix disinfectants for safety. So that
it will stay safe from germs coming from outside.
The water
obtained from different sources contains unhealthy or harmful substances. In which
there are particles of sand, disease-causing particles and many other unsafe
particles which make water unhealthy. This type of water can be cleaned through
many different ways (which will be told next). Usually these germs enter water
through air, surface of the earth or from the holes present under the surface
of the earth.
Water purification
Where pollutants
enter water through various sources. Right there, many forces that clean the
water which have germs naturally. In these forces, there is sunlight which
cleans the running water on the surface of the earth from germs. While the second
source is time. With the passing time the germs present in the water die. And the
dead bodies of those germs combine into sand or soil and settle down in river,
bay, lakes etc. The process of cleaning water present under the surface of the
earth naturally is called “distillation”. The water free from germs is
drinkable. The water we drink and is available in our houses is also cleaned
from many different ways.
