What Is Ozonation and How Does It Purify Water?

Ozonation is a highly effective process for water treatment that uses ozone gas to remove contaminants, disinfect, and improve water quality. The techniques of ozonation of water involve generating ozone and introducing it into the water for oxidation and disinfection. Ozone is typically produced using ozone generators, which convert oxygen from the air into ozone through methods like corona discharge or ultraviolet light.

Once generated, ozone is dissolved in water using different techniques such as venturi injectors, diffusers, or bubble columns. These methods ensure proper mixing and maximize contact between ozone and water. The process is particularly effective in destroying harmful microorganisms like bacteria and viruses, as well as breaking down organic and inorganic pollutants, including pesticides and heavy metals.

Techniques of ozonation of water are widely used in municipal water treatment plants, industrial processes, and even in residential systems for clean drinking water. One of the significant advantages of ozonation is that it leaves no harmful residues, as ozone naturally decomposes into oxygen. However, proper handling and monitoring are essential to ensure safety and efficiency.

In addition to drinking water treatment, ozonation techniques are applied in wastewater treatment, swimming pools, and aquaculture to maintain high water quality. With its ability to provide chemical-free and eco-friendly disinfection, ozonation is becoming an essential technology in modern water management.
