An ozone generator for drinking water is a device that produces ozone (O3) gas, which is used to treat and disinfect water intended for human consumption. Ozone is a powerful oxidizing agent and a natural disinfectant that can effectively eliminate a wide range of waterborne contaminants, including bacteria, viruses, parasites, and organic compounds. Ozone generators for drinking water treatment are commonly used in municipal water treatment plants, particularly for improving the quality of source water (such as surface water from rivers and reservoirs) before it is distributed to the public.

Ozone generators for drinking water treatment can be used in conjunction with an RO (reverse osmosis) plant to enhance the effectiveness of the treatment process. The ozone is injected into the water prior to the RO process to destroy any microorganisms that may have passed through the pre-treatment and filtration stages. This can help to reduce the burden on the RO membranes and improve their lifespan, as well as enhance the overall quality of the treated water.
