Rapid urban growth is putting pressure on governments to provide water and sanitation services. As populations increase and facilities are built closer to residences, it is difficult to site essential wastewater treatment plants. Residents living near industrial facilities are more aware of potential odour issues. SUEZ has developed an integrated odour management system called NOSE that uses both technical and community engagement approaches to characterize, treat, and monitor odour emissions to help integrate industrial facilities into local communities.

Rapid urban growth and
increasing population
density place increasing
pressure on local
governments to provide
sustainable access to water
and sanitation services.
Such challenges can require significant
investment in new infrastructure. At
the same time, traditional buffers
between residential and industrial
sites, including wastewater treatment
plants, are being eroded and residents
are living closer to existing facilities.
As a result, it is becoming increasingly
difficult to find suitable locations
for essential wastewater and water
treatment facilities.

3. 3
With increased proximity to
industrial facilities, communities
are becoming more and more
aware of potential odour nuisances.
Amidst these growing social
pressures and community
expectations, governments are
responding with increasingly
stringent regulatory requirements.
SUEZ has developed smart,
new, reliable and collaborative
approaches to odour management
to better enable the integration
and acceptance of industrial
facilities within local communities.

4. 4
NOSE, developed by
SUEZ, can characterise,
treat and monitor odour
emissions. It is suitable
for both municipal and
industrial applications
including wastewater
treatment, sludge
recycling, industrial
emissions and urban
air quality.

anintegrated
approach
NOSE integrates both technical and human approaches
to improve odour management.
Data from both technical and human approaches is fused to
develop solutions that effectively mitigate nuisance odours.
Solutions might include design or optimisation of suitable
treatment processes, improving building ventilation or even the
use of odour-masking agents.
Technicalapproach
Sources and dispersion of odour emissions identified and
mapped using dedicated sensors, mathematical models
and data such as customer complaints.
Humanapproach
Local community engagement utilising Odour Wheel®
developed specifically for each industrial activity or
neighbourhood. Increased communication between local
residents and operators enables a local ‘Nose Jury’ to
effectively characterise the odour footprint. Residents
are educated on identification of odour types with the
wheel providing useful descriptors, such as ‘burnt
match’ or ‘rotten eggs’, to help identify the location and
source of nuisance odours.

7. 7
OdourWheel®
Odour Wheel®
methodology relates a perceived odour with a recognised
and familiar odour. The tool can be adapted to different industrial activities.
Site operators, customers and neighbouring residents are trained in the
characterisation and recognition of odours specific to the site.
This common language shared by all stakeholders allows development of
a constructive dialogue and integration of the facilities into their social and
environmental context.

odour
management
NOSE consists of a comprehensive range
of solutions ranging from identification
and anticipation of odour sources
through to the treatment and real-time
monitoring of odour emissions.

9. NOSESense
Identify and characterise
olfactory footprint
Potential odour sources are
identified and mapped. We then
measure the odorous emissions
in order to model atmospheric
dispersion and potential impact
on the surrounding environment.
We then use the Odour Wheel®
methodology to characterise the
perceived olfactory footprint.
NOSEMonitor
Anticipate and monitor odorous
emissions
The NOSE platform enables you
to anticipate and monitor odour
emissions, in real-time, using
the latest innovations in sensor
technology. Our ‘Nose Panel’
trains your operators and our
‘Residents Panel’ integrates
neighbouring residents to help
monitor nuisance odours.
NOSEProtect
Treat and control odour

SUEZ offers a wide-range of
proven solutions for effectively
treating odours and reducing
their nuisance impact. Tailored
solutions could include ventilation
optimisation, advanced
biofiltration technologies or
mobile treatment solutions.

NOSE is a proven odour
management solution being
used in over 200 projects
throughout the world.
In France, SUEZ introduced NOSE to collaborate
with the community of Bordeaux, to evaluate the odour
emissions and anticipate nuisance odours from urban
wastewater treatment activities.
In Australia, SUEZ worked with Sydney Water and the
University of New South Wales across six waste water
treatment plants between May 2012 to November 2014
to study odour nuisances associated with biosolids.
Currently, in collaboration with Allwater and SA Water,
SUEZ managed odours associated with the sewage
collection network in metropolitan Adelaide.
