  • Wall mounted oscillating high pressure misting units

  • Mobile oscillating high pressure misting units

  • Perimeter daisy changed high pressure multiple nozzle systems ideal for large sites and can be laid up to 1500 metre

  • ATV mounted odour suppression systems

  • Odour neutralising additives

  • A wide range of pleasant smelling masking additives

  • We all know it’s best to get along with our neighbours and the local community so investing in odour suppression can make all the difference and potentially ward off complaints and fines thus saving money long term.
    Odour explained

    In the first instance it’s advisable that odour is controlled so as not to materially affect your neighbours’ enjoyment of their property, cause them harm or offence or reduce their legitimate use of the environment, and if problems do occur, or are likely to occur, it’s wise to take appropriate actions to prevent or minimise them.

    While for some activities it may not be practicable to avoid all odour, your neighbours have a right to expect that your activities will not detract from their quality of life.

    By “neighbour” we mean anyone living, working, visiting or making use of public space outside your site. It means any sensitive receptor.

    Whether or not odour emissions will cause problems for your neighbours depends on a number of factors.

    The FIDOL acronym is a useful reminder of some of the odour factors that will determine how serious the problem is and what you will need to do as a result.

  • Frequency of detection;

  • Intensity as perceived ;

  • Duration of exposure;

  • Offensiveness
  • Location – in particular, the sensitivity of an individual as influenced by their context.

  • At different levels of odour exposure different responses can be expected:
  • Where no odour is detectable or likely to be detectable, beyond the boundary of your site then no action is required;

  • Similarly, odour may be detectable outside the site but, because of a mix of the above factors, there may not be a problem. For example, the smell of a local baker’s shop can be detected but it only happens in the morning, is usually not considered offensive and, in context, the shop adds amenity to the town. Similarly, the detectable smell of a manure heap from a small, non-intensive farm is usually accepted in the rural context. In such cases no action would be necessary. However, odours from larger commercial operations that are subject to the Environmental Permitting Regulations are generally less well tolerated.

  • At some levels of odour exposure, the appropriate response would be a professional judgement of how serious the above (FIDOL) factors are when weighed together and in considering the cost of reducing odour exposure.

  • [1] The intensity of an odour is a logarithmic function of its concentration. So increasing the concentration of an odorous chemical or mixture by a factor of 10 might increase its perceived intensity by a factor of about 2. Conversely, if a site causes odour pollution, abatement equipment might need to remove ~90 per cent of the odour-causing substances in order to halve the intensity of odour as perceived in the community. Adaptation means that the perceived intensity of an odour diminishes rapidly with constant exposure.

    [1] The offensiveness of an odour is referred to as its hedonic tone. The measurement scale for hedonic tones typically ranges from +4 for very pleasant odours (bakeries, say) to -4 for foul ones (rotting flesh, for example). Neutral odours score 0.

    [1] Location / context: Places where people eat (e.g. houses, restaurants, picnic areas), sleep (e.g. houses, hotels), relax (e.g. houses, parks) or cannot leave or are concerned with health (e.g. nursing homes, prisons, hospitals clinics) will be more sensitive.
