What is Ozone
Ozone is a naturally occurring compound in which three atoms of oxygen are combined to form the ozone molecule (O3). Oxygen most commonly exists as two oxygen atoms (O2). Ozone is formed when energy from ultraviolet (UV) light or electrical discharge break the O2 bonds, forming single oxygen atoms which recombine with O2 molecules to form ozone. Pacific Ozone generates ozone by high voltage electrical discharge (corona discharge).
A Strong Oxidizer
Ozone is an unstable molecule owing 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).
A Natural Disinfectant
In these reactions, the unstable third oxygen atom is transferred, with a large release of energy, from ozone to the molecule being oxidized. The transfer of energy in oxidation causes the outer membranes of microorganisms to rupture. As ozone molecules enter lysed microorganisms, genetic material (DNA and RNA) is oxidized and destroyed. Oxidation typically hydrolyzes inorganic molecules, causing them to become insoluble, and facilitating removal by filtration. Organic molecules most often disintegrate as a result of oxidation, destroying their biological activity.
Ozone. A Green Technology
The potent disinfecting power of ozone can benefit the environment in many important ways. Ozone can replace chlorine, hot water, and steam in many applications thereby reducing the consumption of chemicals and water, as well as eliminating the energy required to produce hot water and steam.
Our Environmental Commitment
The stated mission of Pacific Ozone is to “design, develop and deliver ozone solutions worldwide for the benefit of people and the environment.” This mission clearly underscores our commitment to improving the environment through the application of ozone. We are confident that ozone will play a continually expanding role in saving energy and water.
Feed Gas Preparation
Processes requiring low concentrations of ozone may be serviced with clean, dry air (21% O2). Typically, ozone is generated from concentrated oxygen (>90% O2) to yield higher concentrations of ozone.
Pacific Ozone generators produce high concentrations and volumes of ozone by corona discharge utilizing patented Floating Plate Technology reaction chambers. Oxygen gas flowing through the electrical corona in the reaction cell is converted to ozone (4-8 % conversion is typical, depending on reaction conditions).
In ozone mass transfer, ozone gas is typically dissolved into a stream of water through a venturi injector and transferred to a contacting tank. Pacific Ozone’s pre-configured, integrated Enhanced Mass Transfer system maximizes the transfer rates for each application. Excess ozone gas that does not dissolve into the water stream is vented from the top of the tank through a destruct device that safely converts the excess ozone back to oxygen (O2).
Controls are typically designed into ozone systems to monitor and optimize ozone production and demand. Systems can be designed to automatically compensate for changes in demand and operational conditions to maintain a preset level of residual ozone.
