Having completed a technical and commercial tender process for design, supply, install and commission of 25 fixed continuous Hydrogen Sulphide and/or odour monitoring systems, Balfour Beatty/Morgan Sindall/BAM Nuttall JV (BMB); Ferrovial Agroman Laing O’Rourke JV (FLO) and Costain, Vinci and Bachy Soletanche JV, choose Pollution Monitors “Combined Element” device as their preferred solution across the Thames Tideway Odour Control H2S Monitoring project.
All systems incorporated modern sampling and conditioning systems with duty standby sample lines routed to the air treatment chambers. Each cabinet was manufactured and supplied to meet the requirements of BS EN 61439-2:2011 Low Voltage Switchgear and control gear assemblies, and BS EN 60204-1:2018 Safety of Machinery.
The Combined Element was manufactured and supplied to meet the requirements of Machinery Directive 98/37/EC (amended); Low Voltage Directive 2006/95/EC & EN61326-1:2013 Electrical equipment for measurement, control and laboratory use.
The Combined Element unit continuously monitors parts per million (ppm) concentrations before dour removal and ppb (parts per billion) concentrations of Hydrogen Sulphide and other odorous cross sensitive gases after odour removal, enabling the project team to monitor the performance of the odour control systems and meet the requirements of their odour management plans.
The first system was installed at King Georges Park in Wandsworth in 2022 with the last site being completed by the end of 2024.
