Ozonation

Ozone is a very unstable gas, being made up of three oxygen atoms. It is this instability that makes it a powerful oxidant. By oxidizing all organic substances, ozone destroys pesticides and pathogens (viruses and bacteria).

Water is brought into contact with the ozone from the production units in a tank with several compartments into which ozonated air is driven.

Ozone that has not reacted is recovered and sent to the pretreatment unit.
