  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Waterquality in irrigation canals and boreholes - Greece

    Background Kavala is located in the North East of Greece, 680 km from the capital Athens. The population of the prefecture of Kavala is around 85,000 people. The River Nestos which flows through this prefecture is very important for the agriculture of the area. To allow for a fair distribution of the water for irrigation purposes, a number of Boreholes and canals have been established. The ...

  • Measuring Static Water Levels Made Easier with Eno Scientific

    The Well Sounder 2010 PRO is a sonic water level meter, designed and manufactured by Eno Scientific, to measure static water level in wells, piezometers or boreholes. This portable handheld unit uses sound waves to measure the distance from the top of the well to the water level. This eliminates the need to lower anything into the well. Unlike standard water level tapes these acoustic meters are ...

  • Geodrilling International - Installation of Closed-loop Borehole Probes

    The installation of closed-loop borehole probes is a challenge on almost any project. With many domestic clients requiring a large meterage of borehole to be installed in a small site, Nicholls Boreholes has found that the traditional manual installation of closed-loop borehole probes is no longer a safe or acceptable option. The company has developed the Loop Feeder, a hydraulically-driven, ...

  • World`s Most Advanced and Easiest to Use Sonic Water Level Meters

    A common theme among drillers and environmental monitoring companies is the need to repeatedly measure water levels and until recently that meant constantly lowering and raising heavy measurement tapes. If you were lucky they wouldn't get stuck or break off leading to spoiled test results and expensive repairs. Eno Scientific has solved this problem by manufacturing the ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

  • REMOVING LIMESCALE IMPROVES WATER QUALITY IN POULTRY FARMS

    Water is one of the most important nutrients in poultry production.  About 70 per cent of a bird’s body is made up of water - eggs contain around 65% water. Birds are constantly losing water in egg production, so there is an obvious need for constant replenishment.  Water intake is almost twice the weight of ...

  • Groundwater quality assessment of a freshwater wetland in the Selangor (Malaysia) using electrical resistivity and chemical analysis

    Groundwater quality of the Paya Indah Wetland (PIW) was targeted for the present study using integrated two-dimensional electrical resistivity imaging (ERI) and hydrochemical surveys. Electrical resistivity and the influence of variations in the lake level were investigated using daily water balance measurements, water sampling and geochemical analysis, and well-logging. The geoelectrical ...

Both contracts include the survey and rehabilitation of ...

  • Putting the HAZOP to good use!

    The UK Chemical Industry has, for many years, appreciated the strategic use of Hazard and Operability (HAZOP) assessments in reducing the risks posed by their activities and sites. But what other industries can benefit from this approach? The landfill sector has just begun to demonstrate how the innovative use of the HAZOP assessment methodology can help underpin significant decisions on site ...

  • Network Models in the Control Room the Fact and the Fiction

    In this article Dan Stevens, Senior Support Engineer for Water Distribution Software at Wallingford Software, discusses the potential for Network Models to be used in the control room, what is possible, and indeed what is a sensible level of integration of network modelling with other systems (such as telemetry and SCADA) for a more complete understanding of system operation and performance. For ...

  • Integration of Subsurface Data Management and GIS to Facilitate Model Calibration

    Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÃ’ Geology and any of several popular modelling environments ...
