  • A new hardwire circuit for metering reactivity

    Sub-criticality, criticality, and reactivity are the terms which are not annunciated in Indian PHWRs (Pressurised Heavy Water Reactors) and are thus not very clear to the reactor operators. These parameters are prime movers defining nuclear reactor and should be annunciated in control room by simple means to aid operator to view reactivity excursions while in power operation or during shutdown ...

  • Replacement of Hot Caustic Paint Stripping Process with High Pressure Water Jet System: Ford Australia

    Ford Australia Ltd replaced an existing hot caustic paint stripping process, used for cleaning car skids, with a high pressure water jet system. This project has resulted in annual savings in the order of $300,000 from reduced chemical, energy and waste disposal costs. Significant improvements in paint quality were also achieved through the ability to clean the skids on a more regular basis than ...


  • Decision support system for the optimal design of district metered areas

    The establishment of district metered areas (DMAs) is widely recognized as one of the most effective techniques for the optimal management of water distribution networks (WDNs). However, its implementation in real cases is a very challenging task that requires decision aiding. In this work, a comprehensive methodology for the optimal design of DMAs is presented and discussed. The proposed ...

  • Expert assessment: Sea-level rise could exceed one meter in this century

    Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientific publishers on that topic has revealed. The 90 experts participating in the survey anticipate a median sea-level rise of 200-300 centimeters by the year 2300 for a scenario with unmitigated emissions. In contrast, for a scenario ...

  • Replacement Fill Control Valves with Electronic Flow and Metering Improve Pressure, Stop Leakage and Prevent Valve Failures

    The City of Modesto, California is situated 90 miles east of San Francisco and has approximately 200,000 residents relying on 200,000 of gallons of water a day. The City needed to upgrade three water storage tanks that hold approximately 750,000 gallons each. After years of using motor operated valves to fill water storage tanks, the city recognized that there were just too many problems. ...

  • Innovative Multi-Media Filter – Continuous Backwash Filter

    The disadvantages of conventional MMF based pretreatment Conventional pretreatment is based on multimedia filters (MMF) implemented in large scale desalination plants. Although this filtration method is well proven and provides reliable filtration efficiency, it conceals an inherent drawback, the disadvantages of which relate mainly to the backwashing mechanism. The ...

  • Water quality monitoring with hydrolab MS5

    Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river first disappears underground just outside the ...

  • 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 ...


  • Adaptive water distribution networks with dynamically reconfigurable topology

    This paper presents a novel concept of adaptive water distribution networks with dynamically reconfigurable topology for optimal pressure control, leakage management and improved system resilience. The implementation of District Meter Areas (DMAs) has greatly assisted water utilities in reducing leakage. DMAs segregate water networks into small areas, the flow in and out of each area is ...

  • Grey water recycling system for home office building

    Home Office declares Aquaco grey water recycling system a success! Says Head of Corporate Services Katharine Thompson”: If anyone had an issue with the facilities here, I would be the first to know”. “In fact I had almost forgotten that there is a grey water system supplying the toilets here, it appears to be just as mains water would be,” says Katherine. ...

  • Return of drinking water supply in Paris to public control

    The ‘reclaiming’ by Paris of its water back into public hands is a paradox in the homeland of transnational water companies and at a time when the European Commission rather favours the liberalisation of public services ‘of general economic interest’. Yet what has happened is more complex. A quick historical review of management formulas in Europe reveals both the ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • InfoWorks WS aids Hunter Water’s model aspirations

    Specialist water and wastewater services provider Hunter Water Corporation purchased InfoWorks WS in 2009 to enable advanced real-time modeling of its water networks. Its experience of building complex models from basics has been extremely positive, with the process being made considerably easier than anticipated by the solution’s powerful data import, inferencing and operational tools. ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • How a new source of water is helping reduce conflict in the Middle East

    Scientists and others look to desalination as a way to unite longtime enemies in a common cause. Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped ...

  • Our drinking water systems are a disaster. What can we do?

    In the wake of the Flint, communities turn to innovative technology and financing to prevent the next crisis. People in developed countries turn on the tap and safe drinking water flows, a dramatic health benefit they tend to take for granted. That complacency was dramatically disrupted last year when children in Flint, Michigan, started testing positive for lead poisoning and the ...
