ODOR
The problem of odor nuisance is related to the impact of odors on human olfactory receptors.
These odors are emitted by various sources that emit odorous compounds.
In such a case, it is important to determine the degree of odor nuisance from the plant.
For example, the BAT conclusions on best available techniques for the forging and foundry sector require the following to be implemented in order to improve environmental performance:
preparation of an environmental management system including, among others, an odour management plan and periodic monitoring of odour emissions.
We offer:
- Periodic odor monitoring
performed, among others, by measurement in accordance with the EN 13725 standard (dynamic olfactometry).
- Proposing techniques to prevent odor nuisance along with an analysis of the possibilities of using these techniques. (Our specialists do not select specific devices, but suggest a way to solve the problem).
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.
