Treatment for drinking water production involves the removal of contaminants from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, and minerals such as iron and manganese. Ozone (O3) gas is commonly used in this contaminant removal industrial process as an effective and economical oxidizer. 

 
Teledyne API carries a complete line of Industrial Process O3 instruments to meet all of the process and safety needs in this application. ​
