WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  1. Sludge Thickening – How Our Industry Has Been Calculating Polymer Usage Wrong
    12/14/2018

    Parkson Corporation is pleased to announce the release of the latest video in the Parkson University series, “Sludge Thickening – How Our Industry Has Been Calculating Polymer Usage Wrong.” In this video, we discuss how to correctly calculate polymer use during the sludge thickening process in wastewater treatment.

  2. How To Develop The Best Construction Dewatering Solutions
    12/12/2018

    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.

  3. Enhancing HVAC Performance: Siemens Clamp-On Flow Meters Chosen For NYC Building Complex
    12/11/2018

    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.

  4. Saving Energy And Enhancing Environmental Sustainability At A Top University In Asia
    12/11/2018

    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.

  5. Field Test Turns Clamp-On Ultrasonic Skeptics Into Believers
    12/11/2018

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

  6. How Do You Know If Your Ozone Contacting System Is Well Mixed?
    12/11/2018

    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.

  7. Rotary Drum Thickener Virtual Tour (ThickTech)
    12/6/2018

    The video provides a different perspective on the sludge thickening process and explains how various features combine to make the ThickTech the best option for low polymer usage and the highest capture rates of 98% or more.

  8. 5 Key Steps To Better Plastic Piping Designs
    12/5/2018

    Most people understand the inherent benefits of plastic piping — chemical resistance, installation speed, ease of assembly, cost efficiency, longevity in corrosive, harsh exterior or underground environments, etc. Not everyone, however, fully appreciates the nuances of plastic piping design that help to maximize those benefits most efficiently.

  9. EPA Uses Floating Vegetated Islands To Remove Excess Nutrients From Water
    12/4/2018

    Harmful algal blooms — the overgrowth of algae in water — are a major problem across the nation. Blooms occur when excess nutrients (nitrogen and phosphorus), combine with sunlight, and warm temperatures in water bodies. They can cause severe, negative impacts on aquatic ecosystems, the economy, and human health.

  10. Rapid Microbial Assessment Following A Case Of Legionellosis
    12/3/2018

    A case of legionellosis an illness acquired from Legionella bacteria, which can grow in cooling water and potable water systems was diagnosed at a medical retirement home.
