Wastewater Treatment Case Studies and White Papers

  1. Oilfield Produced Water Desalination Using Innovative Process – From Pilot To Full-Scale Project In Colombia

    Oil & gas production is often associated with extraction of large quantities of ground water. After separation from the hydrocarbons, such produced water (PW) requires further treatment prior to discharge or reuse.

  2. Easy To Digest: H2S Removal Rids City Of Lift Station Odors

    A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. DO2E representatives suggested that the City of Taylorville (IL) use their proprietary digesters equipped with an ozone (O3) capability to remove this problem from our system.

  3. Pump Maintenance Know-How

    Minimize pumping time, cut fuel consumption, reduce costs and ultimately boost profits with greater “pump maintenance know-how.” 

  4. How To Control Activated Sludge With Online Sensors

    The goal for domestic wastewater treatment in the 21st century should be to have a minimal carbon footprint and to be 100% self-sustainable with regards to energy, carbon, and nutrients – while achieving a discharge or reuse quality that preserves the quality of receiving waters (Water Environment Research Foundation (WERF), 2009). Sustainability with respect to energy requires both conservation and production. By Dr. Robert Smith, Ph.D., P.E., BCEE, YSI, a Xylem brand

  5. The Power Of Bundling: BIOSTYR® + ACTIFLO®

    In 1998, Onondaga County signed an Amended Consent Judgment with the State of New York to significantly increase the level of treatment at its Metropolitan Syracuse Wastewater Treatment Plant (Metro).

  6. Look For Advanced Performance And Safety Benefits When Choosing An Ultrasonic Level Switch

    Contact ultrasonic level switch technology was first applied to process control in the 1960s – and continues to provide accurate and reliable liquid level measurement in virtually every process industry today.

  7. Mobile Membrane Systems Provide Emergency Response

    When emergencies inevitably arise, municipal operators need to be prepared to respond immediately to restore services in order to provide safe, reliable water to their customers. Take for example the City of Cisco, Texas.

  8. Making Accurate pH Measurements

    Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.

  9. DM Petroleum Operations Relies On FPI Mag Flow Meter For Tough U.S. Strategic Petroleum Reserve Application

    New tests recently performed by DM Petroleum Operations Company with the FPI Mag® Flow Meter from McCrometer continue to confirm the flow meter’s accurate performance and reliability on two rugged Texas brine disposal lines supporting the U.S. Strategic Petroleum Reserve (SPR).

  10. Pressure Sewers Can Save Millions

    Alternative wastewater collection systems, such as pressure sewers, provide affordable service to municipalities, new subdivisions, and areas where gravity sewers are difficult and expensive to install.
