ODOR
The problem of odor nuisance is related to odors emitted by sources emitting odor compounds affecting human olfactory receptors.
We offer monitoring:
Periodic odor monitoring performed, among others, by measurement in accordance with the EN 13725 standard (dynamic olfactometry).
We also offer ways to reduce the odor nuisance.
These are filtration methods of odor compounds thanks to the use of adsorption technique on the surface of activated carbon, aluminum oxide, zeolites.
The adsorption technique consists in the separation and subsequent retention of gaseous pollutant components (e.g. organic solvents, fragrance active substances or water vapor) on the surface of the adsorbent. Activated carbon and organic substances as well as minerals - alumina and zeolite are most often used as adsorbents. The characteristics of adsorbents include: large specific surface area, appropriate granulate size, hardness, flowability and ease of regeneration.
Three groups of compounds are responsible for the smell:
compounds having carbon in their structure (aldehydes, ketones, aliphatic and aromatic compounds)
sulfur compounds (hydrogen sulphide (H2S), mercaptans).
nitrogen compounds (ammonia (NH3), amines)
Sources emitting odorous compounds occur in almost every sphere of economic activity. Emission sources are divided into:
- unorganized and organized,
- permanent and periodic,
- linear (road, river); surface (landfills); point (exhaust, chimney).
The most onerous and at the same time the most common sources of odor emission include:
- agricultural production, including production farms,
- chemical industry - varnishes, solvents, dyes or even the production of cosmetics,
- rearing and breeding of animals (including fur animals),
- feed production,
- food industry using aromatic compounds, e.g. beer, wine, milk and meat processing,
- slaughterhouses,
- chipboards and chipboards (the process of drying and pressing the boards),
- waste management,
- paper industry,
- treatment plants,
- gastronomy,
- fat industry,
- coffee production,
- fish processing,
- plant protection products,
- refining industry.
