Odour nuisance and
odour measurement
Odour nuisance is a complex matter. In our densely populated
country, companies are often confronted with complaints
about odour nuisance. And often, it's not at all clear
right away which company, out of an industrial area, is
causing this odour nuisance. For all the parties concerned,
it is important not only to find the origin of the problem,
but also to measure the odour nuisance in an objective way
and to map the odour dispersion exactly, before taking any further steps.
Neutral odour experts are the right people for this job :
e.g. sniff measurements can be carried out This way, taking the
meteorological circumstances and odour spread models
into account, the odour source can be defined, as well as
its impact on the surrounding areas.
A sampling of the industrial emissions will allow to
identify by chemical analysis (gas chromatography - GC-MS)
the harmful components and their concentrations, as well as
the odour producing components. Olfactometry tests can be
carried out as well (measurement by an odour
panel, for an objective report on the odour concentration,
report based on a number of well-defined criteria).
Custom-made solutions
Odour nuisance is a complex matter, its solution is equally
complex.
There is no standard solution for an industrial odour
nuisance problem.
It's an utopian thought to believe that odor emissions out of industrial
manufacture can be reduced to zero. But most of the time,
however, it is possible to find an economic and technically
feasible solution. This requires knowledge and experience.
Especially for odour problems, it is important to choose for
a well-considered and technologically sound solution. Merely
install a gas scrubber or filter or use an odour masking
product, will hardly ever allow to obtain a good result. An
experienced partner will have an accurate look at the
problem and offer you an intelligent solution, custom-made
for your company, and perfectly integrated in your specific
manufacturing process. Seen the complexity of this matter,
it is sometimes recommended to carry out some tests
with a pilot plant,
during a certain period. This way, a "theoretic best
solution", can prove itself in practice. During the test
period, samples can be taken and the installation can be
adjusted, if necessary. Especially for more complex odor
treatment problems, this kind of pilot scrubber
installation, will offer the customer as well as ourselves surety about the results to be obtained.
The full-scale odour treatment installation put into
practice
If the odour problem didn't turn out
too complex in the study stage and under certain
circumstances, it is possible to
consider the
biofiltration solution,
in that case, we are mainly talking about odour nuisance from waste
water treatment installations and coming from the agro-industry (composting, food industry, meat processing and
fish processing industry).
If however, the study stage is
showing the need for a gas scrubber or gas scrubbing
installation, it should be considered, under the
circumstances described above, to carry out some pilot
tests. This is, of course, not always a must, but is
certainly indicated for going straight out to a final
solution for the odour problem. Taking into account the
cost and the vexation caused by incomplete solutions, the cost for the
rent of a pilot installation is to be neglected.
More information about the working
principle of gas scrubbers
in general can be found on the relevant page. In the
oxidative gas scrubbers used for odour treatment
applications, the gas emission carrying odour components is
washed or scrubbed with water, with added oxidizing
chemicals (e.g. sodium hypochlorite, hydrogen peroxyde).
According to the flow direction of the
off-gases with regards to the washing liquid, there are
counterflow scrubbers (water and gas are moving in opposite
directions) and there are crossflow scrubbers (water and
gas are moving in cross directions). For certain
applications, a combination of both types will be the
best solution.
In the pictures above, you can find a
brief overview of our realizations in the field of odour
control installations with oxidative odour scrubbers.
