24 hours Water treatment is the process of cleaning water.
Treatment makes the water safe for people to drink.
Because it is a good solvent, water picks up all sorts of natural pollutants. In nature, water is not always clean enough for people to drink. In the 1850s, with the invention of the microscope, we first became aware of germs in our water. In 1902, Belgium was the first country to use chlorine to clean or treat water in a public water supply. Today, almost every city in the world treats their drinking water.
