  • Monitoring network for Scottish ports - Case Studies

    Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...

  • Monitoring mixing dynamics in Toolik Lake, Alaska

    Toolik Lake is 130 miles south of Prudhoe Bay in northern Alaska. It is one of the main monitoring sites of the Arctic Long-Term Ecological Research (LTER) project and a site for studies led by Sally MacIntyre of the University of California investigating the linkages between hydrodynamics and ecosystem function. Both studies are funded by the U.S. National Science Foundation. It is classified as ...

  • Lagoon Discharge Flow Monitoring - Case Study

    Open Channel Flow Monitoring without a Flume or Weir Township operators liked the Greyline AVFM 5.0 datalogger reporting system where formatted flow reports (total, minimum, maximum and average) could be downloaded automatically to a USB memory stick without carrying a laptop to the site. The Township of South Glengarry in Eastern Ontario discharges continuously from their ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • OCF 5.0 open channel flow monitors - monitor infulent at Long Sault WWTP plant - Case Study

    Greyline Open Channel Flow Monitors were installed at the Wastewater Treatment Plant in Long Sault, Ontario when the SBR plant was originally commissioned in 1995. But after 16 years of continuous service, components for the old models became obsolete. Plant operators Caneau Water and Sewage Inc. decided to replace the instruments and new Greyline OCF 5.0 Open Channel Flow Monitors were installed ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

  • Raw water intake monitoring - Case Study

    The Situation Hydrocarbons in municipal water supplies, including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through ...

  • Antifouling System Reduces Algal and Biological Growth on the In-Situ TROLL 9500 Water Quality Instrument

    Abstract New regulations regarding clean water have increased the need for long-term environmental monitoring. As water quality sensor technology improves and becomes more stable, the limiting factor in these projects becomes biological and non-biological fouling of instrumentation. Biofouling of environmental equipment increases site visits and maintenance, which elevate monitoring costs. ...

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 ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
