1,What is ozone we also meet?

Ozone, sometimes called “activated oxygen”, contains three atoms of oxygen rather than the two atoms we breathe.Ozone is one of the most powerful sterilant in the world and can be used to destroy bacteria, viruses and odors and so on . Interestingly ozone occurs quite readily in nature, most often as a result of lightning strikes that occur during thunderstorms. In fact the “fresh, clean, spring rain” smell that we notice after a storm most often results from nature’s creation of ozone.  However, we are probably most familiar with ozone from reading about the “ozone layer” that circles the planet above the earth’s atmosphere. Here ozone is created by the sun’s ultra-violet rays.  This serves to protect us from the ultra-violet radiation. So that can protect our person’s healthy. Here in our field, we can use ozone to purify both waste water and air in household environment and industrial field.

2,How does ozone work?

Ozone is powerful, it has a very short life-cycle. When contaminants such as odors, bacteria or viruses make contact with ozone, they are destroyed completely by oxidation. In so doing, that extra atom of oxygen is consumed and there is nothing left, no odor, no bacteria, no extra atom, only oxygen. Ozone reverts back to oxygen after it is used.so from here we can see it clearly, ozone has no harmful to the environment.  Finally it can become oxygen back to the air, that good for the environment.

3,How does ozone produce?

There are basically two methods of producing ozone, ultra-violet and corona discharge producing .Corona discharge creates ozone by applying high voltage to a metallic grid sandwiched between two dielectrics. The high voltage jumps through the dielectric to a grounded screen and in the process, creates ozone from oxygen present in the chamber. Ultra-violet(UV) light creates ozone when a wavelength at 254nm( nanometers) hits a oxygen atom. The molecule (O2) splits into two atoms(O), which combine with another oxygen molecule (O2) to form ozone(O3). See below two pictures, first picture is ozone plate with its power supply, it is called corona discharge, it is often use for air purify,also we also have the ozone generator which can use for water purify.  and  the second picture the UV light we also sell about it, it is often used for remove the odors from the household.

4,How long does the ozone last?

As soon as ozone is formed in the generator and dispersed in a room, some of it inverts back to oxygen. This step occurs by several processes including the following: Oxidation reaction with an organic material such as odors or smoke. Reactions with bacteria etc. With again consumes ozone by oxidation reactions. Additionally ozone itself has a half life which means that “residual” ozone created( extra ozone) will return to oxygen usually within 30 minutes, in amounts equal to half its level. What this means is that after each subsequent 30 minute period there would be half as much residual ozone left at the end of the period as well present at the beginning of the period. This is similar to a geometric progression of 16;8;4;2;1. In practice the half life is usually less than 30 minutes due to temperature, dust, and other contaminants in the air.  Therefore, ozone, while very powerful, doesn’t last long.  It does its job and then disappears.

5,How can you tell the level of the ozone?

There are a number of methods available, the most common being the Draeger tube. Residual ozone becomes apparent to sensitive humans in the range of 0.01 – 0.03-ppm, or well below the permissible levels for continuous exposure. As noted previously, this residual smell is ozone that has not been consumed by the odors and is now remaining in the air. Our Sihon Electrionics Co., Ltd also carries portable & wall-mount ozone sensors to measure the ozone level inside a room or home.  These sensors are portable and light and can easily detect the ozone levels emitted by the entire line of ozone generators.  Please contact  Sihon Electrionics Co., Ltd to learn more information.

6,What is the right level of ozone?

In the states, OSHA( Occupational Safety and Health Administration) regulates two levels for ozone exposure.  They are 0.10-ppm time weighted average (TWA) for an 8-hour day, and 0.30-ppm for 15 minutes.  In Canada, guidelines vary by province.  The best concentrations for continuous use are in the range of 0.01 – 0.03-ppm, which is well within the guidelines.Different country has different level, if you can, tell me which environment you have located in, i will tell best purify solutions to you.

7, Is the ozone harmful and what if any are the long team effects?

Ozone has been known for almost a century more time , so a great deal of people is known about it. Several regulatory agencies, including the Occupational Safety and Health Administration (OSHA), have stipulated that the safe allowable level of residual is 0.10-ppm (parts per million). Note that this permissible level is for continuous exposure throughout an entire 8 hour day for 5 days a week. The temporary affects of such a low exposure would range from headaches, to sore throats, irritation in the eyes, and nose.  No long term effects have ever been documented from ozone exposure.
