How Ozone Works


About Ozone

When was ozone first used?
The "ozone advantage" is simple, yet profound: chemical free /low or no maintenance! Ozone has been used to treat water for more than a century.

It began in Oudshoorn, Netherlands, in 1893. The first ozone water treatment plant treated their drinking water. Nice, France, was the first large city to use ozone for their drinking water. Now, thousands of communities throughout the world use ozone. Los Angeles, California, is the world's largest (600 million gallons a day) water treatment plant to use ozone for water decontamination. A three-year LACDWP study completed in 1983 proved that the use of ozone as a pretreatment for aqueduct water was the most economical way to meet or exceed new federal and state water quality standards.

Ozone treatment is now easier more efficient and less costly than conventional methods. The "revolution" in ozone treatment is that it works - and works well - at an affordable price.

Ozone is no longer an obscure method of treating water! Ozone has been accepted by municipalities, bottling and beverage companies, the EPA (10 state standards), Wisconsin DILHR, Water Quality Association and many foreign authorities.


Ozone Pure Water is as easy as O1 + O2 = O3

How is ozone made?
Ozone (O3 ) is found commonly in nature. Ozone is formed whenever lightning occurs, or when an electrical discharge creates a spark. The ozone layer in the upper atmosphere provides a protective screen against dangerous solar radiation.
The generation of ozone is a relatively simple process. Air, dry air or oxygen is drawn into our patented ozone generators, at which point the air is charged with high voltage. The air is made up of diatomic oxygen (O2 ) and nitrogen (N2 ) . Diatomic oxygen is a molecule composed of two oxygen atoms (O) held together by four equally shared electrons. As the air is drawn through the ozone generator, the high voltage splits some oxygen molecules into oxygen atoms. Some of these atoms then quickly react with oxygen molecules to form ozone: (O1 ) + (O2 ) = (O3 ) .

Ozone is second only to fluorine as the most powerful oxidant. Ozone inactivates and oxidizes organic metals and most organisms faster than chlorine. Ozone also functions as a micro flocculating agent to "polish" the water and improve clarity (clarifying iron, sulfur and manganese).



The Ozone Process Works In Three Easy Steps

1) Ozone Injection/Oxidation:

Ozone is a tri-atomic oxygen (O3) which has very high oxidizing power. It is a gas produced from air and high voltage electricity. The injection of the ozone into the water. Tiny ozone bubbles saturate every drop of water. At this point oxidation of iron, sulfur and manganese is immediate.

2) Aeration:
The elimination (off gassing or venting) of the ozone and other gasses/odors such as sulfur. This occurs by an ozone stripping action. As water flows down the Off Gas Tank, ozonated water rises and strips any gas in the incoming water. We have designed exclusive Self-Cleaning and Maintenance Free vent devices.

3) Filtration:
The final step for removing the oxidized material is filtration. We formulated SP10 in 1988. It's a natural physical filter media requiring only water for backwash. No chemicals or oxidizing media is necessary. SP10 is non-porous and inert. It yields a high flow and requires a low backwash rate.

When sizing ozone equipment for a job, the same principles apply whether the job is residential, commercial or industrial.

How Does The Ozone Pure Water Systems Work?


Soluble ferrous iron, which is not filterable, is oxidized (the process of adding oxygen) to insoluble ferric iron thus making it easily filtered. Bacterial iron can be killed through oxidation and by denying its food source (ferris iron).

Sulfur/Sulfur Bacteria: 

Odorous hydrogen sulfide, which is not filterable, is quickly converted to elemental sulfur, which can be easily filtered. A portion of the sulfur is de-volatized and off gassed in step #2. Again, the bacterial form is killed and filtered.


Manganese is oxidized and filtered in the same manner as iron.


Ozone oxidizes the organic material in bacterial membranes, which weakens the cell wall and leads to cellular rupture. This exposes the organism to the external environment, which causes almost immediate death of the cell. It's similar to a knife deeply cutting skin. (Bacteria systems are sized differently than iron, sulfur and manganese systems)
