  • In-situ quality monitoring station in Lower Saxony

    Background 'Duemmer' is a shallow lake in the south-west of Lower Saxony; through the lake flows the river 'Hunte'. The catchment area spans 426 km2. With a surface of 12.4 km2 and an average depth of 1.1 m there is a water volume of approx. 14 million m3. Large parts of the lakeside are a nature reserve and the lake is a popular local recreation area. The lake suffers from strong nutrient ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • On-Line Nitrate/Nitrite Probes for BNR Process Control

    ABSTRACTReal time nitrogen monitoring plays an increasingly important role for the successful biological nutrient removal at wastewater treatment plants. Though traditionally dissolved oxygen has been the main process control parameter a greater understanding of the biological mechanisms and process conditions like nitrite/nitrate concentrations to achieve lower effluent values becomes necessary, ...

  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...
