2. National Operations Conference
The importance of training to keep systems functioning and to
allow for future optimisation and saving operating costs.
(A view from odour control facilities)
3. Setting the scene
Training and education key to the successful, long
term operation of the odour control facility.
In addition, the involvement of all stakeholders in
support of the facility operation is critical with respect
to managing expectations.
7. Training - why
Optimise performance
Future optimisation
Save costs
Management of physiological and
emotional aspects to response to air
pollution
8. Education in maintenance – Plant Healthcare
Monitor the actual plant performance
Record the mechanical condition of the plant
Undertake a thorough internal inspection
Calibrate and re-instate any dosing and monitoring
controls
Report on the plant with upgrade recommendations and
maintenance requirements
9. Cost implications
Expenses will escalate to
a minimum of 15 times
the early intervention
costs
$100 bearing
The re-wind costs can be
as high as $10,000
10. Training in action
8.45am – 10.00am
Session 1 – Odour, Odour Measurement &
Regulation
– Odour and Odorous compounds
– Odour measurement
– Regulation
11. Training in action
10.00am – 11.00am
Session 2 – Dispersion modelling
– Dispersion models available, pros and cons of each
– How odour contour maps are generated, i.e. how to
calculate dispersion and generation from a specific
location.
– Regulators viewpoint
12. Training in action
11.15am – 12noon
Session 3 – Wastewater
– Network Odour
– Process Units and factors effecting odour emissions
– Design to minimise odour emission
13. Training in action
1.00pm – 2.30pm
Session 4 – Biosolids
– Compounds present & likely odour emissions
– Main problem compounds
– Odorous Compound formation process
– Anaerobic Sludge Digestion, parameters that effect
biosolids cake odour and possible surrogates for
measurement of biosolids cake odour
– Sludge Handling
– Wastewater processes and effect on biosolids cake
14. Training in action
2.45pm – 4.15pm
Session 5 – Gas treatment
– Covers, capture rates and extraction systems
– Summary of available odour control technologies
17. Education - Stakeholders
Dispersion Modelling results for Case 3,
with the removal of the emissions from the filter
exhaust and from the interceptor tanks
18. Education - Stakeholders
First, the facility management we reengaged to show that
they did have an issue that they needed to deal with but
not with the relatively expensive solution they expected.
Second, the plant operators were trained to identify
operating scenarios that would lead to fugitive odour
emissions from site.
Third, other stakeholders and the local community were
provided with information and assurances that the odour
issues were being dealt with and that there were other
possible causes that would need to be investigated (even a
neighbour’s BBQ!).
19. Education - Stakeholders
By proving that the complaints about odour emissions from the
site were unfounded, the authorities immediately relaxed their
view on the company, who in turn installed a relatively minor
process enhancement costing ₤4,000 as opposed
to their proposed ₤40,000 fire-fighting outlay. In addition,
community relationships improved and the company was able
to focus on their business.
20. Training - Conclusion
As highlighted above, training and education key to
the successful, long term operation of the odour
control facility. This includes the involvement of all
stakeholders in support of the facility operation is
critical with respect the managing expectation
