  4. Upgrading A 100-Year-Old Pump Installation In New Orleans 3/9/2021

    Finding just the right pump for an application can be quite a challenge, especially when the building presents several constraints. Sulzer updated a near antique installation.

  5. Improving Water Treatment Efficiency Via Energy Management, Optimization 9/12/2019

    The cost of water delivered to customers is as much about the energy needed to move it as the chemicals required to treat it. Balancing water chemistry, infrastructure costs, and energy consumption is key to optimizing the overall cost of operation. Experience shows that some astute water suppliers are closer to achieving their ideal outcomes than most people realize. Here are some insights into how that works.

  6. Why You Need To Be Prepared For The Next Superstorm (And How To Do It) 4/19/2023

    Understand why a storm preparedness plan is crucial to overcome challenges such as power outages and equipment damage. 

  7. Case Study: First Municipal-Industrial Water Reuse Project In Virginia! 7/3/2006

    Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water

  8. A Time-Based Alternative To Multi-Stage Biological Nutrient Removal 6/6/2022

    A phase-activated sludge system (PASS) reduces energy consumption by combining the aerobic and anoxic tanks and alternating diffusers between the on and off position based on a preprogrammed schedule.

  9. Is It Time To Upgrade Your Aeration And Mixing Systems? 6/8/2023

    Wastewater plants looking to update or replace aeration and mixing equipment should work closely with an established applied engineering company that provides customized solutions for individual needs.

  10. The Benefits Of A Venturi Meter 2/19/2014

    With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.
