  • Dissolved oxygen measurements in aquatic environments: The effects of changing temperature and pressure on three sensor technologies

    Dissolved oxygen (DO) is probably the most important parameter related to water quality and biological habitat in aquatic environments. In situ DO sensors are some of the most valuable tools used by scientists and engineers for the evaluation of water quality in aquatic ecosystems. Presently, we cannot accurately measure DO concentrations under variable temperature and pressure conditions. ...

  • Accuracy of different sensors for the estimation of pollutant concentrations (total suspended solids, total and dissolved chemical oxygen demand) in wastewater and stormwater

    Many field investigations have used continuous sensors (turbidimeters and/or ultraviolet (UV)-visible spectrophotometers) to estimate with a short time step pollutant concentrations in sewer systems. Few, if any, publications compare the performance of various sensors for the same set of samples. Different surrogate sensors (turbidity sensors, UV-visible spectrophotometer, pH meter, conductivity ...

  • Wastewater treatment down-time `not acceptable`

    Reliable 24/7 monitoring and control of a pharmaceutical company's wastewater facility is fundamentally important to the successful operation of the entire business. This is because failures or down-time in the wastewater treatment process would quickly result in waste stream back up. It follows therefore that monitoring equipment should be extremely reliable and this is why Shasun Pharma ...


  • Great Lakes need great Data Buoys

    One recently finished project was performed by the University of Wisconsin and has comprised the depolyment of two data buoys which are both furnished with a multifunctional Lufft WS501-UMB. These weather ...

  • AquaLab Analyzer provides real-time phosphorus measurement in Everglades

    When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • 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 ...

  • Dairy Crest – Dairy Effluent Treatment Case Study and Partech Water Instruments

    In order to comply with environmental regulations, the food and beverage industry relies heavily on constant monitoring and control of wastewater and effluent, before discharge from the plant. Additionally, if process plants fail to be vigilant when it comes to monitoring all areas of waste treatment, the results can be unsuccessful. Partech’s water instruments are ...

  • Remote monitors track river restoration success

    The Norfolk Rivers Trust has installed a remote river monitoring station that has been tracking water quality and flow before and after river restoration work at an area of ecological importance on the River Nar. Rising in chalk hills to the east of the village of Tittleshall, the river flows south for 2.5 km until it reaches Mileham, then predominately west for 39.5 km through the villages of ...


  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...

  • These fires are huge, hidden and harmful. What can we do?

    Smoldering peat gives off massive quantities of carbon dioxide and other pollutants, but the search for solutions is on. As forest fires devastated Fort McMurray, Alberta, last month, a different sort of fire may have started beneath the ground. Peat, a carbon-rich soil created from partially decomposed, waterlogged vegetation accumulated over several millennia and the stuff ...
