Wastewater Measurement White Papers and Case Studies

  1. Refinery Turns To Thermal Mass Flow Meter
    2/5/2016

    An independent Midwest refiner operates refineries in multiple states with a combined crude oil processing capacity of more than 500,000 barrels per day. The company recently approved a project to improve the safety of its plant and reduce its costs for nitrogen gas used for tank blanketing. Read the full report to learn more.

  2. Continuous Analyzer Integrated Data Validation
    5/28/2015

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

  3. HydroRanger For Accurate, Open Channel Flow Measurement
    11/23/2015

    A municipal wastewater treatment plant (WWTP) in the Western United States had to monitor how much wastewater was coming in to the plant and how much effluent was flowing out to the river after it had been cleaned and treated.

  4. DCS Versus PLC: A User's Guide To Selecting The Most Effective Control Platform For Your Application
    10/11/2013

    Distributed control systems (DCSs) and programmable logic controllers (PLCs) are not mutually exclusive technologies. When the end-use application serves as the basis for making a sound decision, the selection process becomes more efficient, and a more effective outcome results. This white paper provides general guidelines and highlights key considerations when choosing a control system platform. While the details of each application are critical to the selection process, use the following as a guide when designing, specifying, and implementing controller technology.

  5. Water Treatments Mass Exodus To Improved Chemical Dosing
    6/13/2017

    When first moved from water reservoirs, water contains materials that need to be treated and or removed. All microorganisms, flora and fauna waste, assorted dirt and insects all need to be dealt with before, water is fit for human consumption.  It is understood that, water needs to make many detours in its path from raw supplies to the tap.   All these detours start at the treatment plant.  At the plant water goes though applications that remove contaminants such as suspended solids, bacteria, algae, fungi, and minerals such as iron and manganese. The final objective is to turn contaminated debris choked water into safe, drinking water.

  6. Desalination Plants Benefit From MagMeters With Unique Virtual Reference Feature
    11/15/2011
    In certain applications, conventional grounding of electromagnetic flowmeters can pose special challenges. This article illustrates those challenges and sheds light on a unique solution that is especially suitable for problematic applications, some of which are found in desalination facilities.
  7. A Golden Spike In Revenue, Efficiency, And Customer Service With The R900® System
    8/20/2015

    In 2008, the public utility manager in Ogden City, Utah sent out a request for proposal on a system-wide changeout of its meters, absolute encoders, and radio frequency meter interface units (RF MIUs), with a goal of eliminating estimating and replacing all their meters with AMR technology to read year-round. Read the full case study to learn more.

  8. How To Control Activated Sludge With Online Sensors
    10/18/2013

    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

  9. Look For Advanced Performance And Safety Benefits When Choosing An Ultrasonic Level Switch
    6/22/2015

    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.

  10. DM Petroleum Operations Relies On FPI Mag Flow Meter For Tough U.S. Strategic Petroleum Reserve Application
    10/15/2014

    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).
