Ozonation: an advanced process for water oxidation and disinfection
Ozonation is a water treatment technology based on the use of ozone (O₃), a powerful natural oxidant.
It enables complete water disinfection and the elimination of numerous organic, microbiological, and chemical pollutants without adding harmful residues.
This process is used in industrial water treatment as well as in drinking water production, pharmaceutical laboratories, and demanding agri-food processes.
At SFEC, we provide ozonation systems tailored to your water treatment lines or production facilities.
Our solutions meet the specific purity, safety, and performance requirements of each sector.
Our objective: to guarantee disinfected water, free from chemical by-products, while preserving your facilities and the environment.
Operating Principle of Ozonation
Ozonation relies on the generation of ozone from pure oxygen or dry air, followed by its controlled injection into the water to be treated.
Ozone acts instantly as an oxidant and disinfectant before naturally decomposing into oxygen.
Ozone Production
Generation by corona discharge from oxygen or air.
Injection and Contact
Diffusion of ozone into water via an optimized mixing system.
Oxidation Reaction
Destruction of microorganisms and degradation of organic pollutants.
Degassing and Residual Ozone Destruction
Total safety before discharge or reuse.

Questions and Answers
Does Ozonation Replace Chlorination?
Yes, in many applications, ozone offers more effective disinfection without chlorinated residues.
Does Ozone Leave By-Products in the Water?
No, ozone naturally decomposes into oxygen, without generating persistent by-products.
Is Pre-Treatment Required before Ozonation?
Yes, prior filtration or clarification improves the efficiency of ozone/water contact.
Can Ozonation be Used for Wastewater?
Yes, it is effective for tertiary treatment and the reduction of recalcitrant organic compounds.
What Maintenance is Required?
Regular maintenance of ozone generators, sensors, and destructors ensures performance and safety.
