Ozonation is a process that involves the use of ozone gas (O3) to purify air or water. Ozone is a powerful oxidizing agent, which means it can break down pollutants, bacteria, and viruses effectively. This method is often used in water treatment facilities to eliminate harmful microorganisms and improve water quality. In addition to water treatment, ozonation is also applied in various industries, including food processing and air purification. By using ozone, businesses can reduce the presence of harmful substances and enhance the safety and freshness of their products without leaving harmful residues.
