Silsoe Odours Ltd has worked with a range of businesses using air dispersion modelling. It’s particularly helpful if you are involved in the planning of a new waste recycling plant, or an industrial facility that is known to create by-product odour emissions. Understanding how the odours are likely to travel, and their concentration level, is invaluable in being able to predict the impact on the local air quality. If you have an existing facility, you may find air dispersion modelling useful if you’re planning modifications and need to submit a proposal taking into account air quality standards.
Odours disperse naturally in the atmosphere, and understanding the process allows for a mathematical modelling of the odour dispersal and its subsequent impact on the local environment. A plume of odour will progress downwind of its source dispersing its smell in a pattern of short, highly concentrated, duration peaks, lasting a few seconds, and longer periods of low to zero concentration. This patterning is known as the dispersal frequency. Wind direction determines the direction of the odour dispersal, and the wind speed will determine the rate of odour dispersion. Air temperature and the stability of the atmosphere will also play their part in determining the trajectory and frequency of the odour dispersal.
Using mathematical simulations of the effect of meteorological conditions on plumes of odour allows us to determine whether planned facilities, or modifications to existing facilities will be likely to comply with air quality standards, or create a negative impact on local residential communities.
At Silsoe Odours laboratories we develop our dispersion modelling based on years of experience in understanding how odours travel, at what frequency, and the period of dispersal. The resulting data can help businesses understand how they fit in to the eco-system of which they are a part, and recognise the impact they may have on the people they share that eco-system with.
