General Questions and Answers

What Is Ozone? Ozone is a molecular short-lived gas that is formed by oxygen reaction with other oxygen molecules to form 3 parts oxygen. Ozone if formed naturally by bursts of lightning in the stratosphere by an association of UV Light, forming the ozone layer. Ozone reacts with hydrocarbon pollutants in the air. This combination, when measured, gives us the "Ozone Air Pollution Level".

How Is Ozone Generated?

1. Ultra-Violet Irradiation, UV Light can create or destroy ozone depending on the UV wavelength generated by the light. Wavelengths of 185 namometers or (nm) are required for the generation of ozone and 254 nm for the destruction of ozone. These generation methods do not generate enough ozone for effective treatment of highly concentrated waste water. Ozone concentrations of 1 ppm in air are the norm for UV systems and applicable to backyard spas and small household purification systems.

2. Corona Discharge, Corona Discharge is the standard method generating ozone. By using a dried process gas (oxygen or air) passing through an electrified field or "Corona". A glass dielectric is inserted in a stainless steel jacket with a small gap. Air or oxygen is then introduced through a high potential electrode. This generates a usable amount of ozone (1% gnenerated with air and <10% generated with oxygen). Thus, pounds to tons per day of ozone can be generated for industrial waste water treatment applications

History of Ozone

Ozone has been recorded as far back as 1785, but the first industrial generator was developed in 1857. The first full-scale plant was installed in 1893, in the Netherlands. The plant was used for water treatment. The first U.S. plant was in Niagra in 1903. The 3rd U.S. installation was placed in Whiting, Indiana in 1940 and is still in operation. Ozone was achieving wide acceptance in Europe and the U.S.for water treatment until World War I, when inexpensive methods for chlorine generation were developed in the U.S. After the war, the U.S. used chlorine as the primary method for sterilization, while ozone is still widely used throughout Europe today.
