At Silsoe Odours, we carefully select, screen and train our team of odour panel members, or “sniffers”, to conduct odour services including odour testing (including odour characterisation) and sniff surveys. Our rigorous process means you can rely on the accuracy and reliability of all our results. As part of our ongoing training, sniffers participate in odour characterisation training. They learn to identify, differentiate and describe odours accurately.

WHY IS IT USEFUL TO CHARACTERISE AN ODOUR?

Sniffers employ two methods to characterise odours. Firstly, during olfactometry testing. Secondly, during a ‘sniff survey’ conducted near to possible odour emissions.

In the first instance, sniffers describe the nature of an odour sample as a panel member in the olfactomety lab. This information is valuable for operators, as it helps determine whether odour mitigation strategies work effectively. Odour abatement equipment and treatments aim to diminish and improve odours. However, sometimes the impact of an odour is reduced without any improvement in its nature. By comparing odour characterisations over time, you can see whether the odour has become more pleasant.

Sniffers can also characterise odours during sniff surveys. Doing so allows us to pinpoint where an odour originates, where there are multiple possible sources. For instance, if an odour is described as resembling “rotten eggs”, it could indicate that it originates from an anaerobic source, such as a waste storage tank or septic sewer. This can be valuable for validating odour complaints and providing evidence to the regulator.

ODOUR CHARACTERISATION TRAINING

Today, our sniffers are taking part in odour characterisation training. This is a valuable exercise that ensure they can accurately identify and describe different odours. They are presented with a wide range of odorants using ‘sniffing sticks’, similar to felt tip pens. Sniffers learn to identify the differences and associate them with specific odour categories. A useful tool that helps with this are odour wheels, such as the one pictured (which is tailored to wastewater applications). These wheels help sniffers to understand odour categories and can assist in identifying some of the chemicals involved. They also provide a structured reference framework so we can ensure consistency across the team.
