Necessity
of water purification
Water is essential for
our life. Our brains consist of 90% water and our blood is 83% water. Water
supplies oxygen and nutrients to our cells, moisturizes our lungs, regulates
our body temperature and protects our joints. Water purifiers are used to purify water.
There are two types of water
purification process
1.Reverse Osmosis (RO)
2.Ultra Violet (UV)
Reverse Osmosis is a
technology that is used to remove a large majority of contaminants from water
by pushing the water under pressure through a semi- permeable membrane.
Elements removed by RO
are dust particles, colloids organics,bacteria,pyrogens,more
than 99% of dissolved salts(ions) and many more.
Ultra Violet (UV) :Ultraviolet light is an invisible form of electromagnetic radiation that has a
shorter wavelength than the light humans can see. It carries more energy than
visible light and can sometimes break bonds between atoms and molecules,
altering the chemistry of materials exposed to it. UV light can also cause some
substances to emit visible light, a phenomenon known as fluorescence.
Solar water purifiers
work by using sunlight to change contaminated water into fresh-smelling,
good-tasting and safe drinking water. As the sunlight raises the temperature of
the water, the water is vaporized and leaves the dust particle behind.
How do Solar Water Purifiers
Work?
Solar Water Purifiers collect
water in some kind of covered bin. As the sunlight raises the temperature of
the water, the water is vaporized and leaves the contaminants behind. The water
goes through condensation under the glass or plastic cover and drops of water
collect in a pure water channel. The drops are then delivered into a clean bin
from which we can then drink clean water.
Solar water container
store and purify drinking water. And it’s done with the help of solar energy,
requiring no electricity from batteries or mains.
