The treatment and handling of sewage, food waste and many other organic or non-organic materials can very often cause emissions of offensive odours into a processing facility or out into the environment.
These odours can be caused by hydrogen sulphide, solvents and biological compounds which may be detected by the human nose at very low levels.
Envirocare can offer expert UKAS and MCERTS accredited Odour Monitoring to BS EN 13725 (2003).
What is Odour Monitoring?
Assessing odour is an increasingly important exercise for regulators and operators alike.
Because of the potential for malodours to arise from certain activities, regulators are keen to ensure that odours are quantified and in some cases qualified in terms of character and hedonic tone.
Who Needs Odour Monitoring?
Certain industrial processes lend themselves to creating odours more readily than others.
Typical industries that may have to deal with odour problems are:
+ Waste Water Treatment Works
+ Landfill Sites
+ Waste Processing Facilities
+ Abattoirs and Rendering Plants
+ Food & Pet Food Manufacturing
+ Anaerobic Digestion Facilities
Often facilities such as these will be required under their permitting regulations to operate under an Odour Management Plan (OMP).
A key part of the plan is the accurate measurement of odours arising from the installation. With monitoring data in place, the operator can determine options for odour reduction and predict the likelihood of future complaint.
How we conduct Odour Monitoring
Odour is monitored by capturing a sample of potentially odorous gas into an inert Nalophan bag. Within 30 hours of collection, the sample is presented to a panel of human noses at the lab using an olfactometer. The sample is diluted with odour free gas at a known ratio and presented to the panel who are asked to report the presence of an odour.
The sample dilution ratio is progressively decreased (odour concentration increased) and the panel are asked to repeat their assessment. The assessment of the odour panel at different dilution ratios is used to quantify the odour concentration in standardised units (ouE/m3).
