Water Disinfection Using Ozone vs UV Sterilization

The problem of safe and clean drinking water is one of the biggest issues facing both developing and developed nations. Everyone in the world should have access to clean, drinkable water, as it is one of the most valuable commodities in the world. Despite the fact that an increasing number of countries are modernizing, becoming more technologically advanced, the number of people who have access to purified, clean water has not grown correspondingly. Lives and health are at risk when not enough disinfected water is available. In view of the UN’s declaration that access to clean water is a fundamental human right, it is imperative that governments invest in clean water. There are two main methods used in water disinfection such as ozone generators and UV radiation.

It isn’t as simple as purifying our water sources to provide clean, potable water for all. It is imperative that this process minimize the presence and usage of Disinfection By-Products (DBPs) during the process. In addition to impurities, unsafe water can contain allergens, bacteria, and viruses, which can lead to many even deaths in humans and diseases. Decontaminating water can be a complex process that involves many difficulties to overcome.

It has been proven that ozone is a valuable tool for disinfecting water, as it decreases the amount of DBPs that are released into the environment. Oxidizing agents such as ozone can quickly destroy, remove and contaminate them from water without producing harmful byproducts that are the environment and harmful to humans.  Restaurants and central kitchens follow several sanitation procedures. The level of sanitation can vary from one to another. Among the most common disinfection methods are ozonation and UV radiation, which are used for a variety of industries, including food and beverage, healthcare, water lines, and other fields.  

What is Ozone sterilization?

Bacteria and organic compounds are oxidized by oxidizers such as ozone. Ozonation is effective in removing infection-causing bacteria and viruses. As a result of its highly reactive properties, ozone used for disinfection breaks down instantly to oxygen, leaving the surface completely free from additional compounds or ozone. Using ozonation, however, leaves no aftertaste, as chlorine does. As a matter of fact, it has been used extensively for its ability to remove odors.

When comparing UV radiation with ozonated water, ozonated water comes out on top. 

Ozone’s disinfection rate is more than 11 percent higher than UV irradiation according to a study published by China’s National Key Research and Development Program. As a result, ozonation is responsible for the oxidation of both inorganic and organic compounds. The result of this is that ozone is more effective than UV irradiation in reducing pesticide toxicity.

Electrolytic ozonation is a good way to make ozone, since it requires very little energy. Adding electricity to water releases ozone at a concentration of up to 28% ppm, a toxic gas that is deadly to bacteria, viruses, and other microorganisms, but safe to consume. This cutting-edge technology now makes electrolytic ozone affordable, reliable, and easy to maintain. A high-tech method of ozone creation removes nitrogen oxide from the atmosphere without releasing high-purity reactive ozone.

Electromagnetic radiation (EMR) includes ultraviolet (UV) light. Ultraviolet light can be divided into three categories. UV-A and UV-B are forms of radiation that pass through the atmosphere and strike our beaches, giving us both tans and sunburns depending on our sensitivity. UV-C, the highest-energy and most dangerous form of ultraviolet light, is fortunately most completely absorbed by the atmosphere. An effective sanitation method is UV irradiation. UV-C provides the most powerful UV light for killing germs.

Ozonated Water vs UV light

Ozonated water is a cost-effective and time-efficient method of removing quality chemical byproducts at low concentrations can be achieved with electrolytic ozone       

On the other hand, when using it properly, UV light is highly effective, does not contain any chemical byproducts, and is odorless.

Some notable differences between Ozonated Water and UV light are illustrated below.

1. Disinfection

Among industrial and municipal uses of Ozone and UV for water and wastewater disinfection, both are widely recognized. In each case, viruses can be inactivated.

The ultraviolet-based disinfection technology can be used for a variety of industrial applications, including water and wastewater. This disinfection offers several UV treatments for water and wastewater treatment that are fully validated biochemically, and that have been independently verified per recognized regulatory guidelines.

In addition to disinfecting, ozone is also used to reduce iron and manganese as well as taste, odor, and color. For water and wastewater disinfection, ozone or ultraviolet light is both environmentally friendly and effective.

2. Drinking water

The treatment and disinfection of drinking water by ozone and UV is well established. Viruses, bacteria, and other microorganisms can all be inactivated with each. Ozone is a powerful antimicrobial agent that can also be used to remove taste, odor, color and iron, as well as acting as a flocculant. Contrary to chemicals such as chlorine and chlorinated derivatives, ozone and/or UV need relatively short residence times to disinfect.

A drinking water treatment program kills or inactivates viruses, bacteria, parasites, removes organic and inorganic contaminants in the water that have been imported by pollution, and reduces naturally occurring organic compounds such as humic acid and algal metabolites. Water in surface waters such as lakes and rivers often contain more microorganisms, is more likely to become contaminated and requires different treatment than groundwater. Increasingly, countries are setting stricter limits on pathogens and contaminants in drinking water to reduce consumer risk.


UV radiation’s effectiveness under the right conditions, ozonated water has a high reactivity level that allows sanitation to occur quickly without generating any byproducts. Furthermore, UV irradiation requires the exposure of microbes to intense light for a long period of time in order to result in their death.

Due to ozone generator’s permeability, efficacy, and practicality, it has been demonstrated to be a more effective disinfection method than UV radiation.
