What is ozone?
Ozone is a gas composed of three atoms of oxygen (O3). Ozone is the Eath’s Natural Sunscreen and occurs both in the Earth’s upper atmosphere and at ground level.
Ozone is a form of oxygen. As a strong oxidant, ozone is a type of natural sterilizer, which could effectively oxidize (decompose) organic matter. Unlike the usual chemical disinfectant, it neither causes any negative side effects, nor corrosive. In fact, ozone is an environmental friendly sterilizer that reforms into oxygen molecules after the sterilization process. Ozone in the atmosphere is usually produced via ultraviolet ray released by the Sun and through lightning strikes. This explains why we could always feel like there’s fresh air after thunderstorms, as ozone has been produced during the storm and has cleansed the air in the atmosphere.
Ozone is very useful for industries which requires high level of hygienic and sterilizing standards, such as food safety, commercial laundry, medical, water treatment industries and etc. Ozone is also listed as the approved sterilizer by the US Environmental Protection Agency (EPA), and has been utilized across the globe for more than a century. Many running water treatment in developed countries and most packaged drinking water utilize ozone to sterilize.
How is Ozone Formed?
High energy (from ultraviolet ray or lightning) splits oxygen molecules into oxygen atoms.
The free oxygen atom react and form weak bond with another oxygen molecule to create an ozone molecule.
As ozone molecules react with organic molecules, the oxygen atom with the weak bond will be released, thus oxidising the organic matter.
Ozone molecule will reform into oxygen molecule (oxygen) after oxidising the organic matter.
The way to generate ozone
Ultraviolet Light (UV Ozone Generator)
Raw Material: Air Filter; Consumable: UV Lamp
Using ultraviolet ray with certain wavelength (185mm) to radiate through the oxygen molecule, oxygen molecules will be broken and produce ozone molecules. This type of ozone production are commonly used in cupboard disinfection process, and the ozone product by the UV method has not more than 0.3% purity.
Corona Discharge Method
Raw Material: Atmosphere Air or Pure Oxygen; Consumable: Air Desiccant, Air Filter, Oxygen Production Machine.
The principle of corona discharge method for producing ozone is to place a dielectric body parallel between two parallel high-voltage electrodes and maintain a certain discharge gap. When high-voltage alternating current is applied between the two poles, a uniform blue-violet is formed in the discharge gap. Corona discharge, when air passes through the discharge gap, oxygen molecules are excited by electrons to obtain energy, collide with each other, and polymerize into ozone.
The corona discharge method is currently the most common form of ozone generation, and the purity of ozone generated by the corona discharge method is up to 6%. The corona method produces oxygen in the corona air (20%) while coronarating the nitrogen in the air (78%) and producing by-product nitrogen oxides (NOx), while corona discharge using pure oxygen. The law does not produce nitrogen oxides.
Electrolytic Ozone Generation (EOG)
Raw material: Water；Consumable: Pure water
The principle of membrane electrode electrolysis to produce ozone is to use low-voltage direct current to conduct positive and negative two-pole pure water of solid-state membrane electrode. Water is separated into hydrogen and oxygen molecules in the form of proton exchange at a special anode interface, and hydrogen is directly from the cathode. Emission, oxygen molecules are excited by electrons generated by high-density currents at the anode, and are polymerized into ozone.
The purity of ozone produced by electrolysis is about 20% or more. The by-products of the production of ozone by electrolysis are oxygen and hydrogen, and no nitrogen oxides (NOx), and air humidity is not considered.
iEOG Electrolytic Ozone Generator Principle
Pure water enters electrolysis.
Decompose into hydrogen and oxygen atoms after electrolysis.
Oxygen atoms are produced at the anode, Hydrogen atoms are generated at the cathode and discharged.
Oxygen atoms recombine into
ozone (28%), oxygen (72%)
Difference Between Ozone Gas & Ozonated water
Ozone gas is a natural oxidant (bactericide), but the gas has no directionality and cannot sterilize the surface of the object.
If water is used as a medium and the ozone gas is efficiently dissolved in water, the directionality of the ozone gas can be achieved. Instead of many chemicals, the surface of the object is disinfected.
According to the OSHA (Occupational Safety and Health Association) regulations in the United States: the average ozone concentration exposed for 8 consecutive hours in the working environment should not be higher than 0.1 ppm to prevent respiratory tract sensitivity and cough, so it is necessary to control the air in the application of ozone gas.
Concentration and ventilation to maintain the environment, however, ozone gas has been used so far, there has never been a case of death due to ozone.
Importance of Ozone Gas Purity
The amount of gas that can be dissolved per unit of water molecules is limited.
Therefore, the purer and less impurity source of ozone gas will determine the concentration of ozone water after dissolution.
If the source of ozone gas is not pure, other gases will also be Dissolved in water.
The purity of ozone gas generated by Baxter iEOG is high, and ozone water does not contain other substances except ozone gas and oxygen.
The Benefits of High Purity Ozone
For example, in the carbonated beverage industry, since carbon dioxide needs to be driven into water by pressure, when it is necessary to dissolve more carbon dioxide, the purity of the gas in the water source is relatively important, and the more impurities, the relative influence of the efficiency of carbon dioxide dissolved into the carbonated beverage.
iEOG can produce high-purity ozone gas. Due to the limited gas per unit area of water, the use of high-purity ozone gas (no nitrogen, less oxygen) can greatly increase the efficiency after mixing, because more effective ozone can be dissolved. In the water, in addition to the high concentration, the gas aeration is also small, achieving the advantages of safety and low post-treatment cost.
