    How To Develop The Best Construction Dewatering Solutions

    Basic construction activities today are more complex than ever when it comes to environmental concerns. Dewatering is a common necessity for contractors and developers today. In addition to ensuring a safe construction site, contractors must be aware of groundwater disposal constraints and regulations.

  • Enhancing HVAC Performance: Siemens Clamp-On Flow Meters Chosen For NYC Building Complex
    Enhancing HVAC Performance: Siemens Clamp-On Flow Meters Chosen For NYC Building Complex

    A commercial real estate corporation that owns, develops and operates premier properties in major North American cities was one of the earliest companies to recognize the benefit of individually metering tenants for their utility usage. When designing a prestigious building complex in New York City, the company sought a flow meter that would facilitate this task. After careful consideration of several options, the choice became clear: clamp-on ultrasonic flow technology from Siemens.

  • Saving Energy And Enhancing Environmental Sustainability At A Top University In Asia
    Saving Energy And Enhancing Environmental Sustainability At A Top University In Asia

    At one of the most prestigious universities in Asia, the main campus comprises a large number of buildings clustered within an area less than 2 km2 (1.2 mi2). Because the university was built more than a century ago, many facilities on the campus were never fitted with the proper instrumentation for energy measurement, making it difficult or impossible to monitor the performance of most HVAC systems, including the cooling system.

  • Field Test Turns Clamp-On Ultrasonic Skeptics Into Believers
    Field Test Turns Clamp-On Ultrasonic Skeptics Into Believers

    After having been reluctant of using clamp-on ultrasonic flow meters for energy measurement in cogeneration plants in large residential and commercial buildings, a USbased engineering firm was convinced by the clamp-on meter’s strengths.

  • How Do You Know If Your Ozone Contacting System Is Well Mixed?
    How Do You Know If Your Ozone Contacting System Is Well Mixed?

    Mixing is something that is often taken for granted when designing systems for water and wastewater treatment. Perhaps “taken for granted” is too harsh a term. Let’s instead say that while designing a treatment unit operation or process, mixing as a phenomenon is automatically assumed to occur – an assumption that forms the basis for process controls, performance guarantees and measurement methods and locations.

  • Clamp-On Ultrasonic Flowmeters: How They Measure Up

    Not cool enough in summer. Not warm enough in winter. Guests staying at a prestigious country club in New York state complained regularly about the air conditioning and heating of their luxury suites and apartments. The geothermal heat exchange system serving this facility had never, in fact, been fully functional.

  • How Farms Can Tend To The Energy-Water Nexus, Reduce Costs, And Help Their Communities

    Across the country, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use — often called the energy-water nexus — is taking its toll on America’s agricultural industry.

  • Fine Screening System: The More Intelligent Primary Clarifier

    In the discussion about limited resources and energy saving in sewage treatment plants innovative sewage treatment methods are increasingly becoming a focal point. In Germany, there are about 1,200 sewage treatment plants which are designed for 10,000 to 50,000 PE, about one third of them have a sludge digester. Thus, there is a potential of about 800 sewage treatment plants that remains for a change from aerobic sludge stabilisation to processes with anaerobic sludge stabilization.

  • How To Turn Data Into A Difference-Maker

    With the proliferation of sensors, data collection, and cloud storage, there is the potential for operational insight heretofore never available, and the opportunity will only expand as the technology evolves and the Internet of Things becomes, well, more of a thing. But data is only truly useful if it informs decision-making that results in positive impact — for an organization's bottom line, its personnel, its customers, or even the world at large (i.e., the environment).
