  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...


  • Groundwater depletion compounds China’s water scarcity

  • 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 ...

  • 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 ...

  • Application of machine learning techniques to predict anomalies in water supply networks

    Methods to improve the operational efficiency of a water supply network by early detection of anomalies are investigated by making use of the data streams from multiple sensor locations within the network. The water supply network is a demonstration site of Vitens, a Dutch water company that has several district metering areas where flow, pressure, electrical conductance and temperature are ...

  • 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 ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Case study - Remote water quality monitoring in South Africa

    Situated in the Mpumalanga province of South Africa, the Xstrata Coal South Africa (XCSA) runs several open cut and underground mining operations producing thermal coal. To ensure their mining operations do not affect the surrounding natural water bodies, the company employs Hydrolab and OTT water quality monitoring equipment with remote data transmission options: the OTT ecoLog 800 water level ...

This is the Red Box Electro Coagulation system whereby contaminants are flocculated by an electrical process into a size which can then be filtered, pressed and disposed of. The ...

  • Managing the Earth from Space: Satellite and sensing technology in water management

    Approximately 200 miles above the Earth’s surface, two satellites circle the planet, always between 106 and 193 miles apart. But while these twins—called Gravity Recovery and Climate Experiment (GRACE)—live in space, they’re providing invaluable assistance in managing natural resources on the ground. GRACE has created a unique picture of ...

  • Abha water utility comes out on top with automated control valves

    Abha is a small modern city in the fertile mountains of southwestern SAUDI ARABIA. Its cool summers make it a popular destination for tourists, but in general the population hovers around 250,000. The city has a new reservoir on top of a hill that releases water through 6 km of piping down to its main Noaman reservoir. The top tank is 100 meters higher than the lower tank. This makes for a great ...
