A Simple Guide to Ozone Water Treatment

Ozone water treatment is an advanced and highly effective way to purify water. But what is ozone, and why is it used in water treatment?

 

What is ozone?

Ozone (O₃) is a form of oxygen made up of three oxygen atoms. It is a powerful oxidant, meaning it reacts quickly with bacteria, viruses, and other contaminants.

In water treatment, ozone is generated on-site using oxygen and electricity. It is not stored or transported like chemicals such as chlorine.

How does ozone work?

Ozone works through oxidation. When added to water, it breaks down:

• Bacteria and viruses

• Parasites

• Organic pollutants

Ozone (O₃) is more than just a word on a chemistry chart—it is a powerful oxidant that has shaped how we clean water, purify air, and protect the environment. From its discovery in the nineteenth century to the high-tech ozone generators we use today, this remarkable gas has become a cornerstone of sustainable industrial practices. In this article, we will take a closer look at ozone’s history, its unique properties, and its wide-ranging applications—including a growing role in aquaculture. What Is Ozone? A Natural and Industrial Wonder Ozone is a naturally occurring gas formed when oxygen molecules are exposed to electrical discharges or ultraviolet light. Its strong oxidizing power allows it to break down microorganisms, pollutants, and unwanted chemicals in both water and air. Because of this, industries across the globe rely on ozone to improve efficiency, safety, and sustainability. A Quick History of Ozone Back in the eighteenth century, chemist Martinus van Marum noticed a distinct smell during his electrical experiments—a scent that we now know is ozone. It was not until 1839, however, that Christian Friedrich Schönbein officially identified and named the gas, using the Greek word ozein, meaning “to smell.” He also recognized its strong oxidative properties, setting the stage for centuries of innovation. The Rise of Industrial Ozone Technology Ozone technology began to take shape in the late 1800s. Werner von Siemens built the first industrial ozone generator, opening the door for commercial applications. By 1886, the first ozone purification company was in operation, and in 1893, the Netherlands installed the world’s first ozone-based water treatment system. The city of Nice, France, followed in 1906, introducing ozone into drinking water purification on a larger scale. Modern Applications of Ozone Today, ozone has a wide range of industrial and environmental uses:

• Water Purification: Ozone effectively removes bacteria, viruses, and chemical contaminants. It is especially effective in freshwater systems. However, in seawater or water containing bromide, ozone can react to form bromate, a potentially harmful compound. By carefully controlling the process, modern ozone systems minimize this risk while still providing safe, clean water.

• Food Industry: Ozone helps sterilize fruits, vegetables, and meat, extending shelf life without leaving chemical residues.

• Air Disinfection: Hospitals, laboratories, and industrial facilities use ozone to remove airborne pathogens and unpleasant odors.

• Swimming Pools and Spas: Ozone reduces the need for chlorine, creating cleaner and more skin-friendly water.

• Aquaculture: Fish farms increasingly rely on ozone to maintain high water quality, control pathogens, and reduce the use of chemicals.

• Industrial Processes: Ozone is used in pharmaceutical manufacturing, wastewater treatment, and chemical-free cleaning.

Addressing the Challenges While ozone is highly effective, it is not without its challenges. In certain waters, ozone can react with naturally occurring compounds to form byproducts that may be toxic. For example, bromate can form in bromide-rich waters, and some transformation products may arise when treating trace contaminants. The good news is that engineers and scientists have developed methods to control these reactions, making ozone both safe and sustainable for modern industrial use. Looking Ahead Ozone technology continues to evolve, offering energy-efficient and environmentally friendly solutions for water treatment, aquaculture, air purification, and beyond. As industries seek to reduce chemical use and increase sustainability, ozone is poised to play an even bigger role in the future of industrial processes.
