  • Black-odor water analysis and heavy metal distribution of Yitong River in Northeast China

    The black-odor mechanism of Yitong River was analyzed based on survey and monitoring results. We found that organic matter is the main pollution source of Yitong River and its tributaries. A black-odor evaluation model that can describe the pollution of the Yitong River water system was developed, and this model has the parameters I = 0.21 [CODCr] + 0.18 ...

  • Multi-point monitoring of nitrous oxide emissions in three full-scale conventional activated sludge tanks in Europe

    The large global warming potential of nitrous oxide (N2O) is currently of general concern for the water industry, especially in view of a new regulatory framework concerning the carbon footprint of water resource recovery facilities (WRRFs). N2O can be generated through different biological pathways and from different treatment steps of a WRRF. The use of generic emission factors (EF) ...

  • Water Level Monitoring and Control Solutions for the UK Internal Drainage Boards

    Pulsar Process Measurement have been involved in design, manufacture and supply of non-contacting Ultrasonic Level and Pump Control systems for the Internal Drainage Board industry for many years. Three typical examples of the application of this equipment are installed at North Level IDB Cross Guns Pumping Station. The original Cross Guns Pumping Station was built in 1938 to house three 760mm ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Application of CCME Water Quality Index to Monitor Water Quality: A Case Study of the Mackenzie River Basin, Canada

    All six ecosystem initiatives evolved from many years of federal, provincial, First Nation, local government and community attention to the stresses on sensitive habitats and species, air and water quality, and the consequent threats to community livability. This paper assesses water quality aspect for the ecosystem initiatives and employs newly developed Canadian Council of Ministers of 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 ...

  • Diurnal fluctuation of zinc concentration in metal polluted rivers and its potential impact on water quality and flux estimates

    Diurnal fluctuations of metals have been observed in the South Tyne river catchment, UK, in both upland tributaries and major river reaches. Zinc exhibits the most pronounced cyclicity, with concentrations increasing during the night to a maximum near 05:00 before decreasing during the day. This trend is the inverse of pH and temperature observations, which are thought to be the predominant ...

  • Optimal sampling network for monitoring the representative water quality of an entire reservoir on the basis of information theory

    This study presents a method for optimal selection of sampling stations for representative and effective water quality monitoring of a reservoir on the basis of information theory. We adopt an objective function used for the design of other hydrological monitoring networks such as rain gauge networks. Unlike rain gauges, in which only a single variable of rainfall is of interest, water quality ...

  • Can natural variability trigger effects on fish and fish habitat as defined in Environment Canada's metal mining environmental effects monitoring program?

    The Metal Mining Effluent Regulations (MMER) took effect in 2002 and require most metal mining operations in Canada to complete Environmental Effects Monitoring (EEM) programs. An “effect” under the MMER EEM program is considered any positive or negative statistically significant difference in fish population, fish usability, or benthic invertebrate community EEM‐defined endpoints. Two ...
