Project: Nuisance Odour Detection and Prevention
Location: Camberley Sewage Treatment Works
Products: Jerome J605 Gold Film Hydrogen Sulphide Analysers in Environmental Housings

Camberley Sewage Treatment Works (STW) is situated between the Yorktown Industrial Estate and Watchmoor Business Park on the edge of Camberley, and treats and disposes of sewage from the Camberley catchment area. The works are bordered by a school and a mix of domestic and business properties.

The nearest residential properties are just under 300m away to the east and persistent complaints regarding the characteristic “bad egg” odour associated with hydrogen sulphide (H2S) pervading the local neighbourhood lead to threats of prosecution from the Surrey Heath Borough Council. Consequently, in order effect rapid detection and elimination of these odours, Thames Water have procured from ABLE Instruments several of the venerated Jerome J605 H2S Analysers in environmental housings for fixed point monitoring as previously, successfully implemented at Thames’ Mogden and Acton STW sites.

The analyser systems have been located at the site perimeter and in key process areas such as aeration lanes and around settlement tanks. As opposed to a hard-wired interface with the site SCADA system, Thames Water have deployed Isodaq’s Frog Loggers for capture and wireless transmission of the data from the Jeromes. This will be monitored by the Innovations and Compliance teams.
