The designation of 'sensitive areas' following the EC Urban Wastewater Treatment Directive, has created increased pressure for removal of nitrogen and phosphorous (N&P) from sewage effluents. There will also be pressure to tighten ammonia consents to meet the EC Freshwater Fish Directive. Utilities have allocated funds for upgrading plants in planning submissions to meet these requirements.
To assure N, P and ammonia removal at all times to the required level, online instruments will be needed for monitoring / control. This project will provide validated cost of ownership / performance data for instruments to be included in works upgrades to meet these new challenges.
The project will also examine the optimum use of final effluent monitoring data. For operations, it will investigate alarm strategies, interpretation of results against consent requirements and data access. Possible asset management indicators derived from the data will be identified and guidance produced for data compression / archiving.
Benefits to Clients
- Reduced risk of sewage effluent compliance failures.
- Tested performance and cost of ownership data for known final effluent monitoring needs to the end of the next planning period (2010 in England and Wales).
- Specification and applications data leading to cost savings on equipment selection.
- Obtaining maximum value in the operational use of final effluent monitoring data.
- Guidance on data archiving requirements for asset management to enable ease of use and to minimise costs associated with data storage.
