Odour reduction on organic compounds of approx. 60% - 90%. Straightforward technology in drains and extraction systems. The ozone splits the oxygen atom away from the ozone molecule.

Odour control with ozone

Odour control with ozone in drains and extraction systems is one of the simplest approaches currently available. Agrozone systems produce highly concentrated ozone gas from compressed-air and inject that into the air stream to be treated. The ozone generator with full control can be installed in any location, thereby rendering major structural modifications unnecessary.

Air treatment systems from Agrozone have common odour reduction on organic compounds of around 60% - 90%.

The significant benefit of the Airline air treatment system is its technical design and configuration. Most technologies are designed to generate ozone (ionisation) directly in the air stream to be purified. The drawback of this approach is the need, in many cases, for major structural modifications. In addition, the purification equipment often becomes contaminated as dust and other substances settle.

What is ozone?

In nature, the ozone layer high up in our atmosphere is created by the sun’s UV rays hitting oxygen atoms. In the event of a severe thunderstorm, ozone can also be formed at ground level due to the impact of lightning on oxygen atoms. In addition, ozone can also be created artificially by means of electrical discharge, also known as a corona discharge.

Ozone is known for its oxidising capabilities. As ozone (O3) consists of three oxygen atoms, it is richer in oxygen than O2, which we breathe in every day. When ozone (O3) comes into contact with normal air (O2), a chemical process occurs. In practice, it means that the oxygen atoms in ozone attach to odour molecules and oxidation occurs.

In der Natur schützt Ozon unter anderem uns Menschen vor den schädlichen Auswirkungen der Sonneneinstrahlung, ist aber auch bei der Vernichtung von Bakterien, Viren und Gerüchen sehr effizient. Ozon ist nur dann wirksam und effektiv, wenn der Ozonbedarf vor der konkreten Anwendung bestimmt oder getestet wurde.

How does ozone work?

When ozone comes into contact with an odour or a Volatile Organic Compound (VOC), the oxygen atom splits away from the ozone molecule. The ozone molecule reacts with the odour or VOC and oxidises it into harmless, non-odorous substances which contain primarily CO2 and H2O. In all reactions, the generated ozone reverts to its natural O2 form. This means that ozone is a highly environmentally responsible system that is free from harmful residues. Since the ozone molecule is unstable, the ozone will revert to O2 even if there is no reaction.

The balance between the quantity of ozone required and the desired odour reduction is important to odour control. As long as the balance is sized correctly, release of excessive ozone into the environment will be prevented.

The ozone requirement is determined by air speed, temperature, odour content, VOC, bacteria and fungi.

What is the right level of ozone?

Odour control is custom work and highly dependent on air speed, temperature, VOC and the type of odour. With this in mind, we always recommend a pilot test in order to assess the operation in practice. We then treat a partial stream (200 Nm3/hour) of the air stream with a flexible, temporary setup.

The following parameters are determined during this test:

  • Temperature;
  • Air flow;
  • Pressure;
  • Ozone concentration.

In addition to the aforementioned parameters, the odour concentration should also be recorded independently, by a certified laboratory:

  • Odour concentration at inlet;
  • Odour concentration at outlet, with varying ozone production
