Ozone is a very powerful and effective oxidizing agent. It is mainly used to degrade organic contaminants (color, odor) and enhance formation of particles present in the water prior to filtration.

Ozone is generated on site with limited storage or handling concerns, but the ozone gas is poisonous.

In ‘clean processes’ or ultrapure water applications, ozone is mainly used for CIP sanitization purposes in the process water loops. The dissolved ozone must be removed from the process water to prevent contact with ingredients. Breakdown of (residual) ozone is therefore essential in these and other applications before the ozonated water can be utilized or continue in the treatment process.

The process to reduce the amount of ozone in water is called “deozonation”. It is often used in process water to reduce the amount of residual ozone.

Ultraviolet light destroys ozone in water very quickly and easily. Ozone absorbs the wavelength emitted by low-pressure UV lamps; 254 nm is most optimal.

The mechanism for breakdown of ozone is called ‘photodissociation’. The ozone (O3) molecule is converted into harmless oxygen (O2).

UV light is a proven method to quickly break down ozone. Its big advantage is that UV light does not require filtration or additives that may leave behind residuals in the treated water.
