Wastewater Case Studies and Whitepapers

  1. Integration Of Membrana Ultrafiltration And Gas Transfer Membrane Technologies Produces High Quality Water And Controls Corrosion In Cooling Water System
    2/11/2015

    By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.

  2. 7 Ways To Optimize Your Water Utility
    2/24/2014

    Streamlining utility management and operations yields significant savings.

  3. The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)
    8/5/2015

    A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

  4. New And Innovative Rare Earth Technology For Low-Level Phosphorus Removal
    9/18/2014

    With environmental regulations continuing to restrict the discharge of phosphorus from wastewater treatment facilities, traditional methods of phosphorus removal are proving inadequate.

  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. Top 10 Questions You Should Ask When Purchasing A Control Valve
    3/13/2017

    Automatic control valves, much like everything else we purchase these days, are not all created equal. Some fall into the high quality bracket with pricing to match, while others hover closer to the lower quality and price sensitive end of the scale. Unfortunately, when evaluating control valve prices, it is not always clear what you are being offered and what standards the valve actually meets. Here are a few questions to consider and ask the supplier to ensure you get years of trouble free operation that lasts longer than it takes the sales person to drive out of your parking lot!

  7. How To Select The Most Effective Blower Technology For Wastewater Applications
    9/16/2014

    Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.

  8. In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
    5/1/2016

    Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.

  9. Wastewater Treatment Plant Takes A Bite Out Of Tough Solids
    1/16/2009

    The City of Hammonton’s original steel bar screen rusted while continually allowing debris to pass through to the oxidation ditch and final clarifier. Floatables found their way through the plant to the UV trough, clogging the RAS and internal recycle pumps along the way. Managers of the Hammonton Wastewater Treatment Plant took on the challenge of finding a more efficient screening system. By JWC Environmental

  10. ICEAS SBR Technology Improves Effluent Water Quality For St. Joseph WWTP
    3/15/2015

    St. Joseph Sanitary District No. 1, near La Crosse, WI, operated a wastewater treatment plant (WWTP) that served approximately 1,000 residential customers.
