Ozone’s ability to rapidly neutralize biological matter and eliminate metals provides an effective contaminant removal process.
Ozone water treatment systems can efficiently disinfect water and remove a wide range of contaminants, including bacteria, viruses, parasites, metals, bad tastes and odors, and turbidity.
Disinfection of Water
To achieve effective disinfection of water in the contaminant removal process, ozone water treatment utilizes the oxidative strength of ozone to neutralize biological matter and eliminate metals. Ozone, injected into water through ozone water treatment systems, effectively oxidizes organic material in bacteria and viruses, making water safe for consumption.
The oxidation process also targets and removes iron, manganese, and copper from water, ensuring the purity of municipal water supplies. With its rapid action, ozone is highly effective in disinfecting water, providing a powerful alternative to traditional chlorination.
Breakdown of Pollutants
In ozone water treatment, pollutants in the water are broken down and removed through the powerful oxidation process of ozone gas. Ozone gas reacts with contaminants in the water, oxidizing them and weakening their cells. Metals like iron, copper, and manganese are turned into solid particles and can be filtered out.
Ozone can be created through electrical or UV ozone generators. Electrical ozone generators use corona discharge to produce ozone, while UV light ozone generators disrupt oxygen molecules to create ozone.
This breakdown of pollutants and contaminant removal process is achieved through the oxidation by ozone. It’s effective in removing organic material and biological matter from the water supply, making it an essential component of water treatment systems, particularly in conjunction with processes like ozonated water and reverse osmosis water.
