Ozone is one of the most powerful commercially available oxidizing and disinfecting agents. With Evoqua’s lineup of ozone systems, we are able to deliver a safe, tested, and qualified solution for ozone water treatment. To learn more about this trouble-free approach to sanitisation and disinfection see the list of frequently asked questions below.
Ozone is a naturally occurring compound in which three atoms of oxygen are combined to form the ozone molecule (O3).
Ozone is formed when energy from ultraviolet (UV) light or electrical discharge forms single oxygen atoms which then combine with O2 molecules to form ozone. Ozone is created naturally in the stratosphere by short wavelength ultraviolet radiation. Ozone is most commonly produced for industrial use by high voltage electrical discharge (corona discharge). Pacific Ozone™ systems generate ozone by corona discharge.
Ozone is an unstable molecule under ambient conditions due to the weak bonds holding the third oxygen atom. This instability makes ozone a naturally powerful oxidizing and disinfecting agent. Oxidation occurs when ozone molecules come in contact with oxidizable substances, including microorganisms (viruses, molds, and bacteria), as well as organic and inorganic compounds (metal ions, plastics and rubbers).
Oxidation can be defined as the chemical interaction of oxygen-containing molecules with the substances they may contact, living organisms to metals. Oxidation produces chemical changes characterized by the loss of electrons. In ozone oxidation reactions, the unstable third oxygen atom is transferred, with a large release of energy, from ozone to the molecule being oxidized. In disinfection the transfer of energy via oxidation results in the rupture (lysing) of the outer membranes of microorganisms. As ozone molecules enter lysed microorganisms, genetic material (DNA and RNA) is oxidized and destroyed. With respect to the treatment of metal-containing substances, oxidation by ozone typically hydrolyzes inorganic molecules, causing them to become insoluble, and which facilitates removal of the oxidized metals by filtration.
Ozone is often used as an anti-microbial agent. Ozone is very effective at oxidizing and destroying organic and other compounds. Here are some typical applications for ozone water treatment:
Agriculture/ Produce/Food Processing
• Fresh produce, fruit washing and sanitising • Meat and seafood sanitisation • Produce preservation • Equipment and surface sanitisation • High-purity process water •
Aquaculture
• Incoming water treatment • Wastewater management and disinfection • System sanitisation • Product processing •
Beverage
• Product water preparation • Product water production • Clean-in-place (CIP) • Tank, equipment sanitisation • Bottle and cap washing • Bottled water preservation • Source water treatment • Equipment and surface sanitisation •
Commercial Facilities & Datacenters
Industrial
• High-purity process water • Cooling tower water • Equipment and surface sanitisation • Clean-in-place • Textile Manufacturing • Cooling and boiler water treatment •
Laundry
• Improve disinfection • Cost savings: water, energy, labor • Cleaner, softer laundry • Extend linen life •
Ozone is often used as an anti-microbial agent. Ozone is very effective at oxidizing and destroying organic and other compounds. Here are some additional applications for ozone water treatment:
Marine
• Potable water/effluent treatment • Process water • Ballast water, macrofoulant eradication • Seafood processing • System sanitisation •
Pharma & Biotech
• High-purity water sanitisation • Tank and system sanitisation • Product water production • Clean-in-place (O3-CIP) •
Product Processing
• Groundwater and Soil Remediation • Degradation and neutralization of organic contaminants • Oxygenation of target zone (accelerates bioremediation) •
Wine
• Barrel washing • Equipment and surface sanitisation • Tank clean-in-place (CIP) •
Ozone quickly and naturally decomposes back to oxygen; therefore, ozone is considered environmentally friendly. [1]
Ozone is safe when used properly. In fact, the FDA has approved ozone for drinking water treatment and food processing. [2] [3]
Yes. The USDA has determined that organic foods that are processed with ozone may be labeled as organic. [4]
Please see the material safety data sheet.
Please see the ozone material compatibility document.
Yes! Ozone can be a sustainable solution. With the help from Evoqua’s Pacific Ozone™ system expertise Evoqua customers have experienced reducing annual power and water consumption, reducing annual process downtime, reducing annual maintenance hours, in addition to reducing product loss due to quality*.
*With different processes and designs in the factories, these results may vary. Results are dependent on the incumbent solution when considering ozone as an alternative and again are contingent on the facility's operational practices and facility design
We utilize a patented floating plate technology to produce ozone. In addition, our generators are air-cooled which results in less maintenance, lower power consumption, and ease of installation.
Evoqua’s Pacific Ozone Systems use an innovative floating plate technology to produce ozone which allows us to be very compact without compromising the efficiency of our ozone generators. In addition, our generators are air-cooled which results in less maintenance, lower power consumption, and ease of installation.
Our fully integrated system incorporates all the required elements to generate, measure and control ozone residual. With Evoqua Ozone systems, all you need is air, water, and electricity to increase the efficiency and safety of your process.
