Ozone was first used in water treatment in the late 1800s and is more widely used in Europe and Asia than the United States.
Ozone (O3) is an inorganic molecule composed of three oxygen atoms, formed by the method of Corona or Electric discharge similar to a lightning strike. It is a bluish gas with a very distinctive odor and is one of the strongest oxidizing agents found in the world today.
Ozone is used as a stand-alone technology in some cases. It can also be combined with hydrogen peroxide (H2O2), ultraviolet light or active chlorine to perform an advanced oxidation process (AOP). This AOP produces highly reactive hydroxylradicals (•OH). These reactive species are the strongest oxidants that can be applied in water. They are used to address contaminants with high chemical oxygen demand (COD) or non-biodegradable molecules. They also improve the overall quality of the water.
Ozone is created using an ozone generator. This exposes a stream of air to either UV light or to a high voltage electrical discharge, the method known as corona discharge. We use the corona discharge method which is typically preferred and takes place by breaking apart the two oxygen atoms of an oxygen molecule, then charging one of those atoms to another oxygen molecule, thus creating ozone molecules. Ozone must be created. It cannot be stored or packaged because of its instability.
In a water treatment application, the raw water passes through a venturi injector, which creates a vacuum and pulls the ozone gas into the water. Since the ozone will react with other contaminants or metals to create insoluble metal oxides, post filtration is sometimes required.
Which is better?
Both ozone and chlorine can be used to treat these organisms. Chlorine has long been the default choice. It is a powerful oxidizer and is very effective at treating many pathogens such as Legionella, C. diff, coliform, and cryptosporidium in water systems. However, factors such as environmental issues, maintenance issues, long-term cost, particulate removal effectiveness, and health issues have made ozone the preferred choice for many.
Ozone, like chlorine, is an oxidizing agent effective at eliminating bacteria in water. It is recognized as among the strongest and fastest commercially available disinfectants and oxidants for water treatment. While chlorine does kill many microorganisms, it cannot treat all water-borne pathogens if used at EPA approved doses. On the contrary, ozone can while remaining well within EPA regulations. When ozone decomposes in water, the free radicals that are formed, hydroperoxyl (HO2) and hydroxyl (OH) and play an active role in the disinfection process. Bacteria are destroyed by protoplasmic oxidation, which results in cell wall disintegration.
