Ozone (O3) is a powerful oxidizing agent used in water treatment including the oxidation of organic chemicals. SEKO's professional ozone probes are a trusted solution for industry professionals worldwide.

Ozone is currently the second most widely used disinfectant for drinking water after chlorine, although its use is almost exclusively limited to industrial countries that have efficient water networks.

Therefore, it is used to pretreat the source of water at the origin and subsequently allow chlorination with a lower dose of chlorine in the distribution system.

Although ozonation has the power to effectively disinfect water, this method is not suitable for most applications in developing countries due to the high cost and the need for maintenance infrastructure.
