Posted on

Ozone is a rare formed oxygen. It has 3 oxygen atoms in it, arranged in a tiny triangle. The 3 atoms don’t get along well in this arrangement, so after some time ozone breaks up to release an atom. This atom can be quite dangerous, because it will react with almost anything.

We all have heard of the ozone layer and its depletion around our atmosphere.

But there is a lot of ozone right around us and not just in the sky.


Ozone the pollutant: Ozone is formed when sunlight breaks up the nitrogen oxides that come from cars and factories. Since it is reactive and can cause rusting and corrode metal objects. It is also a greenhouse gas and if you inhale ozone it cause irritation and itching of nose and lungs.

Ozone – the Purifier:

Interestingly what makes ozone bad also makes it good, since it releases reactive oxygen atoms, you can use it to kill deadly bacteria in your drinking water. Water contains bacteria that can cause disease like dysentery, cholera, typhoid etc.

When you bubble ozone through water, the oxygen in it react with the cell walls of the bacteria in water. This makes the cell wall weak and bacterium burst upon.

Uses of Ozone

1. Ozone is also used for killing bacteria in fruit juices, cooking oil and other liquid foods.

2. In some warehouses, ozone is released in a sealed room where fruits and vegetables are kept. This way bacteria and fungi die and fruits don’t rot.

3. Ozone is also used to clean swimming pools and even municipal water supply.

The nice thing is that the reacted oxygen bubbles out leaving nothing behind. So you are left with a pure and safe glass of drinking water. !!!
