Odour Management is of enormous importance to water utility and industrial companies. Ensuring the impact of odour from their facilities is minimised is essential to maintain good relationships with the local community and businesses.
WRc developed the idea of an Odour Management User Group in 2017 to include representatives from water utilities across the UK that were directly or indirectly involved with the management of odour. The sessions were very well received with a very comprehensive range of subjects discussed including root causes of odour, control technologies, modelling, instrumentation and monitoring techniques, management plans and the views of the Environment Agency on the importance of odour management.
In a challenging area such as odour control, where expertise is spread across the UK water companies, there is a need to share knowledge and experience and to aid the adoption of best practice and the 2017 group gained huge benefit from the collaborative approach.
Following the same format as last year, the 2018 User Group also consists of 4 meetings with the first meeting been held in July at WRc, Swindon with 7 utility companies participating in this year’s collaboration.
Presentations were given on the importance of managing septicity and odour by David Sivil, WRc, septicity and corrosion on sewer networks by Peter Henley, WRc, and optimising/minimising the dose of nitrate by Daniel Atwood, Yara. This was followed by all participants sharing case studies on their own applications and issues facing their utility network. A target list of issues the Group will potentially focus on going forward include:
- Proactive odour management and how complaints can be minimised;
- Effectiveness of various odour control chemicals for different scenarios;
- The applications of activated carbon for odour control, its odour removal properties and can the reuse of carbon from water treatment processes save money;
- Odour issues arising in sewage works;
- Exploring the odour emission implications from enhanced sludge digestion systems;
- Discovering innovations for odour problems that cannot be stopped at source.
