  • 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 ...


  • Why Water Scale is Dangerous for Equipment

    Mineral scale occurs wherever circulating water exists, and it forms very fast (generally less than 3 weeks). Even a very thin layer, it will also cause insulation, make equipment inefficient, increase cost, and in some serious cases, it will shut down the whole system and even cause explosion. These problems have already existed in different fields, and are becoming worse and worse. ...

  • Water Quality Monitoring for the “Big Four Parameters”

    Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates. For most water ...

  • Continuous water quality monitoring on Kolubara River

    The first automated station for water quality monitoring located in Beli Brod on the Kolubara river has launched on July 2008. The station was established as the result of RHMSS participation in Twinning project financed by EU, where RHMSS was entrusted with the Component 2 of this project. Installed equipment continually records values of water level, temperature, pH, electroconductivity and ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Case study - Water quality monitoring and weather data at Pampulha Lake-Brasil

    In 2010, OTT Hydromet's partner in Brasil,  Hexis began working with CETEC. This resulted in the installation of a buoy, equipped with an automatic profiling system, in early 2013. The project’s objective is the continuous monitoring of the lake’s water quality, with focus on improving this by the 2014 World Cup Games.  Adcon, Lufft and OTT technologies (Hydrolab DS5X ...
