Ozone is a powerful oxidizing agent that has been widely studied and used for its disinfecting properties. When it comes to water treatment or sanitation processes, ozone is effective against a broad range of contaminants, including bacteria, viruses, and various organic compounds such as phenols.

For bacteria, ozone acts quickly to disrupt cellular membranes and inactivate these microorganisms, making it a preferred choice for disinfection in various settings. Its efficacy against viruses is also noteworthy; ozone can denature the proteins of viruses, rendering them inactive. This is particularly important in settings such as drinking water treatment, where controlling viral pathogens is essential for public health.

In addition to microorganisms, ozone is capable of breaking down complex organic molecules, such as phenols, which are often found in industrial waste and can be toxic or harmful at low concentrations. By oxidizing these compounds, ozone reduces their harmful effects and aids in improving water quality.

Given its multi-faceted effectiveness against amoebic cysts, bacteria, phenols, and viruses, ozone indeed has a broad spectrum of activity, making it suitable for addressing various contaminants in water treatment and sanitation processes.
