Q. 29

Explain traditional ways of purifying water to make it fit for drinking.

Answer :

There are different ways of purifying water like:

Boiling


Filtration


Distillation


Addition of Chlorine tablets


Boiling: Boiling water is the safest method of purification. Boiling is enough to kill pathogenic bacteria and other harmful microorganisms.


Filtration: In this method, water is purified by passing it through a filter which is some kind of a membrane. Filtration collects the suspended impurities in water and purifies it.


Distillation: In distillation, water first gets boiled into vapor and it is then condensed back into liquid in a separate container, thus making it pure.


Chlorination: Chlorination is a commonly used chemical method for purifying water. It is done by adding chlorine tablets or bleaching powder to the water.
