What is the term for source water treatment that utilizes ozone?

The term associated with source water treatment that uses ozone is preoxidation. This process involves the addition of ozone to water to oxidize undesirable contaminants before the water undergoes further treatment. Ozone is a powerful oxidizing agent that can effectively remove organic compounds, particulates, and certain inorganic substances from the water.

Using ozone in preoxidation can enhance the removal of sensitive contaminants and improve the overall quality of water by breaking down complex molecules into simpler, less harmful ones. This treatment step is often crucial in preparing the water for subsequent processes, like filtration or disinfection, ensuring these later treatments are more effective.

The other terms mentioned—prestorage, carbonation, and filtration—refer to different processes that do not specifically involve the use of ozone for treating source water. Prestorage involves holding water for a period before treatment, carbonation refers to the addition of carbon dioxide to water, and filtration is the physical process of removing particulates from water, none of which include the use of ozone.
