Model Masterdeo Line -Bio-based odor neutralizer
These products are the result of the study of natural plant substances (flowers, fruits, herbs, roots, etc.) and the development of processes of industrial biosynthesis in order to design complex mixtures of fragrances and essential oils which can neutralize any odour and gas emission coming from industrial manufacturing processes, wastewater treatment plants and zootechnics. Unlike the traditional air fresheners, the odour neutralizers of the MasterDeo line do not mask the smells in the air but neutralize them completely.
The neutralization relies on the chemical or physical destruction of the molecules that build the odours.
HOW DO WE MEASURE THE ODOURS?
- Analytical methods: gas chromatography, mass spectrometry valid for specific substances dissolved in gaseous fluids. They do not reveal the origin of olfactory harassment .
- Olfactometric method: human noses, appropriately selected assessors trained to recognize the intensity and the pleasantness of odours.
- Sensory methods: electronic noses, biosensors that combine the action of olfactory receptors and physical-chemical transducers of the signal.
- Olfactometric Unit (OU) expresses a value that combines the odour concentration threshold and its air dilution.
WHAT DO THE ODOUR NEUTRALIZERS CONTAIN?
- vegetable extracts of plants, herbs, flowers, fruits and essential oils, properly mixed to act specifically against any odour molecule.
- common excipients (propylene glycol) and surfactants (which make them soluble in water).
MECHANISM OF ACTION
The odour neutralisation occurs with different chemical reactions for each substance which has to be treated:
- Construction the foul-smelling gas reacts chemically with the neutralizing molecule and forms an odourless compound (ammonia).
- Combination the foul-smelling gas is combined with a pleasant odour forming a third lightly scented or unscented product (chlorine derivatives).
- Counteraction when you add to a bad smelling substance another one that opposes to it, interferes with it and finally eliminates the odour (derivatives of sulphur).
- Absorption a foul-smelling substance is absorbed by the neutralizer and forms an odourless product (styrene).
- Chemical reaction all the ingredients of the neutralizer interact with the bad odours and form an odourless product (mercaptans).
- Collection the micelles of some ingredients capture the odour molecules in the air, they create then a heavy drop that falls to the ground and holds the odours.
HOW THEY APPLY
- Neutralization in the air: indoor application, wastewater treatment plants, sludge accumulation tanks, porous floors, toilets, urinals, scrubbers and fireplaces.
- Contact neutralization: landfills, composting plants, waste disposal, sludge tanks, wastewater treatment plants, septic tanks, stables, farms, chemical toilets and well drains
The odour neutralization against the smell pollution
The problem of the odours from industrial and composting plants, landfills, wastewater treatment plants etc. is becoming more and more important. Nowadays at a national level there are no specific regulations and no limit values for the odour emissions. The current legislation about the air quality, the waste and the wastewater treatment refers however to the prevention and the reduction of odour annoyance. Some Regions have already introduced some laws and regulations regarding the reduction of the odour emissions and have set the upper limits of emissions in the atmosphere before the forthcoming adaptation to European guidelines. The “odour annoyance” is part of the regulations concerning the emissions of pollutants in the atmosphere, even though there are no benchmarks to verify the intensity of the odour emissions. The bad smell is considered as a true form of environmental pollution.
