  • Locating Leaks for Cooling Water Systems

    This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline.  Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises ...

  • Secondary Oil Containment at US Army Corps of Engineers - Big Bend Dam - Case Study

    Big Bend Dam takes its name from the unique bend in the Missouri River seven miles upstream from the dam. Construction of the dam began in 1959 and the embankment was completed in July 1963. Big Bend dam is 95 feet (29 m) high and 10,570 feet (3,220 m) in length. Power generation began at the facility in 1964 and the entire complex was completed by 1966. The hydroelectric plant generates ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • LED Applications for Oil and Gas Refining and Processing

    Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Innovation and location in the multinational firm

    This paper provides an overview of the relationship between multinational corporations (MNCs) and local economic systems. It examines the implications of a decentralisation of innovative activity within MNCs for their interaction with local networks. It is shown that this interaction depends upon the type of cluster, whether a general centre of excellence or a specialised centre. These two ...

  • LIMS Locates the Diamond in the Rough

    From the earliest days of digging into the earth for minerals, one question has been raised by all those seeking to make use of the materials the earth offers up:  what exactly have we dug up and is it what we hoped it would be?  Well we’re not panning for gold anymore and hoping for a glint of something shiny at the bottom of our pans, unless we hobbyists.  Modern ...

  • Assessment of relative impact of reservoir location

    Reallocation of reservoir storage capacity for different water use purposes is regarded as one of the representative strategies for supplying water for human and environmental needs under the difficult situation of new reservoir construction. However, there are impacts of reservoir storage reallocation on river/reservoir systems because each reservoir in a multiple reservoir system is operated ...

  • Optimal location of DG for maintaining distribution system stability: a hybrid technique

    To enhance the distribution power quality and maintains the voltage stability is a challenging tasks in the complex distribution network. This can be achieved through the distributed generation (DG). In this paper, a hybrid technique has been proposed which improves the distribution stability by allocating the DG at the optimal place. This technique uses the artificial neural network (ANN) and ...

  • Geostatistical techniques for approximate location of pipe burst events in water distribution systems

    This paper focusses on the customisation and further enhancement of the recently developed data-driven methodology for the automated near real-time detection of pipe bursts and other (e.g. sensor faults) events at the district metered area (DMA) level. Assuming the availability of pressure/flow data from an increased number of sensors deployed in a DMA, the aim is to: (i) overcome the ...

  • Locating subverted processes using random packet comparison in SCADA systems

    A supervisory control and data acquisition (SCADA) system may be subject to integrity attacks. Anomalies in sensor measurements may be used to detect these attacks, but such techniques do not permit us to locate attacking nodes. We propose a novel technique to enable this. Each participating network node probabilistically copies packets and marks them with routing information, before encrypting ...

  • Transient tests for locating and sizing illegal branches in pipe systems

    In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...
