The Application of Ozone in Drinking Water Disinfection

Currently, ozone is widely used in the sterilization and purification of drinking water.

 In developed countries such as those in Europe and America, ozone is mainly used for sterilization in the production and packaging processes of drinking water.

 Current data shows that about 80% of water treatment plants in developed countries use ozone for water purification, while in China, about 40% of drinking water plants use ozone to disinfect water bodies. Compared with other water purification methods, ozone has stronger oxidizing power, can remove more bacteria and pollutants from water, and has no harmful residues, no secondary pollution, no unpleasant odors, and does not affect the taste of water.

The shelf life of bottled drinking water and beverages depends on the effectiveness of microbial elimination. 

It is difficult to completely eliminate microorganisms from water using only ultrafiltration and ultraviolet disinfection processes.

 When ozone is used, it can not only completely kill microorganisms but also remove soluble salts such as iron and manganese from the water. 

It is worth noting that if the original bromine content in the water is high and the ozone dosage is inappropriate, it will generate disinfection by-products called bromate. Bromate is a type 2B carcinogen.
