Ozone for Drinking Water

Ozonation is a water treatment process that disinfects and purifies drinking water using ozone. It is commonly used in municipal water treatment plants and bottled water production. Ozone, generated from oxygen, is injected into the water to eliminate pathogens and remove unpleasant tastes and odors, ensuring safe and high-quality drinking water.

What is ozone treatment for drinking water?

Ozone treatment is a water purification process that uses ozone (O₃), a powerful oxidizing agent, to disinfect and remove contaminants from drinking water. It is effective against bacteria, viruses, and other pathogens.

How does ozone treatment work?

Ozone is generated on-site and injected into the water. The ozone molecules react with and oxidize contaminants, breaking them down into harmless substances, and then decompose back into oxygen, leaving no chemical residues.

What are the benefits of using ozone for drinking water treatment?

Ozone is a highly effective disinfectant that can eliminate a wide range of pathogens. It also improves water taste and odor, removes organic and inorganic impurities, and does not leave harmful by-products.

How is ozone generated for water treatment?

Ozone is typically generated using ozone generators, which produce ozone by applying a high voltage to oxygen or air. The ozone is then dissolved into the water through diffusers or contact chambers.

What contaminants can ozone remove from drinking water?

Ozone can effectively remove bacteria, viruses, protozoa, algae, biofilms, organic compounds (like pesticides and pharmaceuticals), iron, manganese, and sulfur compounds.

How does ozone compare to chlorine in water treatment?

Ozone is a stronger oxidant than chlorine and can eliminate a broader range of pathogens without forming harmful disinfection by-products like trihalomethanes (THMs) and haloacetic acids (HAAs) that chlorine can produce.

What are the environmental benefits of using ozone for water treatment?

Ozone treatment reduces the need for chemical disinfectants, minimizes the formation of harmful by-products, and improves overall water quality without contributing to chemical pollution.

What equipment is needed for ozone water treatment?

Key equipment includes an ozone generator, an ozone contactor or diffuser, ozone monitors, and safety devices to manage and control the ozone concentration in the water and ambient air.
