Ozone Generators

An extremely effective oxidizer, ozone can be used to disinfect water and to help remove a number of contaminants. Unlike other water disinfectants like chlorine, however, ozone cannot be stored and transported so it needs to be generated right where it’s going to be used. At US Water Systems, we have a range of ozone generator water treatment systems with the right concentration and flowrate for your needs. Call our ozone engineers at 1-800-608-8792 for help in sizing your system.

How an Ozone Generator Produces Ozone

In order to make ozone for water treatment, an ozone generator typically uses one of two methods: ultraviolet (UV) or corona discharge. The UV method is the less expensive of the two, but it also produces ozone in lower concentrations, in most cases. Corona discharge is more expensive, but the units are often smaller, use less energy, and produce higher concentrations of ozone. Ozone can also be made using the cold plasma method, but these commercial ozone generators tend to be quite expensive.

UV Ozone Generators

An ozone generator that uses ultraviolet light works in much the same way that the sun’s rays create ozone in the Earth’s atmosphere. The oxygen in the air around us has the chemical formula O2, which means that two oxygen atoms are bound together. When oxygen is exposed to UV light, some of those bonds are broken, separating the two atoms. Those individual atoms join with existing O2 to create O3 – better known as ozone.

Because ultraviolet light is relatively simple to produce, you can often find UV ozone generators for sale at a lower price. This method of generation does have some drawbacks, however, including the fact that the ozone produced tends to be of a relatively low concentration – often 0.5% or lower. This type of system also requires a relatively long time for the ozone to be produced. UV systems do not need oxygen concentrators or air dryers, however, which helps lower the price.

UV ozone generator water treatment is often used for swimming pools, spas, and water features.

Corona Discharge Ozone Generator

Like UV systems, a corona discharge ozone generator also breaks apart O2 so that it can recombine to form O3. This type of generator uses an electrical spark to split the atoms apart, much like lightning does during a thunderstorm. When the high voltage passes through an air gap, it transfers energy to the oxygen molecules, which are split and recombine.

An illustration showing how ozone is generated through the corona discharge method

The corona discharge method is the most commonly used in commercial ozone generators because it can produce more ozone in higher concentrations more quickly. This type of generator works best with dry air, however, as the water vapor in the air can cause nitrogen oxides and nitric acid to form as a byproduct of ozone creation.

Adding Ozone to Water

No matter which method an O3 generator uses, once the gas is created, it needs to be added to the water being treated. This is typically done using an ozone injection manifold or an ozone diffuser. An injection manifold forces untreated water through a narrow opening, which creates a partial vacuum that pulls ozone from a delivery line into the water. An ozone diffuser, on the other hand, sits at the bottom of a contact tank. Ozone is released from the diffuser and bubbles up through the water.

How Does Ozone Treat Water?

Ozone is an oxidizer, which means that it causes a molecule or ion to lose one electron. Losing an electron changes both the molecule and the ozone. Ferrous iron, for example, cannot be easily removed from water because it’s dissolved. When it’s exposed to ozone, however, the ferrous iron becomes ferric iron, which no longer stays dissolved and can more easily be filtered out. This is how ozone and other oxidizers can help treat water that contains difficult to remove contaminants.

Perhaps more importantly, ozone generator water treatment is very effective at disinfecting water. Ozone is very unstable, and it breaks down into O2 easily. When an organic molecule – including most bacteria, viruses, and cysts – is exposed to ozone, one of the oxygen atoms separates and bonds to the organic molecule instead. This damages the molecule, usually breaking open the cell membrane and killing the organism.

Ozone is considered one of the strongest oxidizers known, and is the strongest that’s commercially available. It leaves no residue in water, and water treated with ozone is completely safe to drink. In fact, most commercial bottled water is purified with ozone.
