Odour Control

DiaZone aerosol ozone-water fogging systems are the most effective means for destroying many unpleasant and unwanted odours. Ozone is an extremely powerful oxidant that reacts with and breaks down the molecules that cause malodours.

There are many substances that cause unpleasant odours and these generally fall into two categories, namely, (1) gaseous inorganic compounds and (2) volatile organic compounds.

Ammonia and hydrogen sulphide are considered to be the main causes of odour in the inorganic compound category. Hydrogen sulphide is produced by sulphur reducing bacteria and microorganisms. Organic compounds associated with bad odours include mertcaptans, indoles, inorganic acids, aldehydes, ketones, and organic compounds containing nitrogen and sulphur atoms. These compounds typically originate from the anaerobic decomposition of higher molecular weight substances such as proteins.

Ozone is an extremely powerful oxidiser that kills microorganisms of all types including sulphur reducing bacteria. Ozone also breaks down odorous organic compounds and, in the process of oxidation, destroys smells of all types. Ozone raises the level of oxidation in all compounds (that are oxidisable) to their highest level. For example, sulphides are oxidised to sulphates, nitrites to nitrates and even organic carbon can be mineralised to carbon dioxide.

Ozone is often used in its gaseous form to control odours. Our HydroZone™ aerosol ozone-water fogging system provides an effective solution for breaking unpleasant odours and for odour control generally.
