The relationship between water quality and health has always been known. Clear waters were considered clean waters while swamps were considered dirty areas and unhealthy waters.

Water disinfection has been used for a long time.

Two basic rules can already be found in ancient times (since 2000 BC) which said that waters should be exposed to sunlight and filtered with charcoal. Impure water had to be boiled and a piece of copper introduced seven times, before filtering the water. There are descriptions of ancient civilizations in reference to boiling water and storing water in silver containers. To carry out water purification, copper, silver and electrolysis techniques were used.

Disinfection has been used for many centuries. However, disinfection mechanisms were not known until a few hundred years ago.

In 1680 Anton van Leeuwenhoek developed the microscope.

The discovery of microorganisms was considered a curiosity. It would be another two hundred years until scientists used this invention, the microscope, for the identification and comparison of microorganisms and other pathogens.

The first multiple filter was developed in 1685 by Italian physicist Lu Antonio Porzo).

In past centuries man has suffered from diseases such as cholera. It was said that these diseases were caused by punishments from God or due to the impurity of the air that was a consequence of a change in the alignment of the planets.

In 1854 the cholera epidemic caused a large number of deaths in London. English doctor John Snow discovered that the cholera epidemic was caused by the pumping of contaminated water. The spread of cholera was prevented by closing all pumping systems. After this event, scientists have carried out studies and research on the presence of microorganisms in the water and the method of elimination for the supply of water suitable for consumption.

In the century the effects of disinfectants on water for its treatment and disinfection were discovered. Since 1900, disinfectants have been used extensively by water companies to prevent the spread of diseases and improve water quality.
