Wastewater Instrumentation White Papers & Case Studies

  1. Versatility Of Thermal Mass Flow Meters
    3/10/2014

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

  2. How Can Seasonal Establishments Treat Their Wastewater Economically?
    2/20/2014

    Opened a few months per year, seasonal establishments typically experience important fluctuations in the number of visitors. Energy consumption and operating expenses must continually be analysed and optimized. The implementation of efficient energy management practices and the integration of innovative wastewater treatment solutions that can improve their cost-efficiency ratio have become major sources of savings for this whole industry.

  3. Aeration Basin Air Flow Monitoring At A Stockholm Wastewater Plant
    12/20/2013

    At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

  4. 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

  5. Ultrasonic Metering For Small Water Meter Applications
    9/19/2013

    For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water.

  6. Upcoming Standards And Compliance Regarding Lead-Free Requirements
    9/18/2013

    Badger Meter has and will continue to manufacture and provide products that meet the requirements of current and future lead-free standards. This white paper discusses these changing industry needs both as they relate to Badger Meter products and to water utilities in general.

  7. Bringing Efficiency And Confidence To Wastewater Analysis
    8/19/2013

    Maintaining the quality of wastewater (WW) effluent is more important than ever before, as municipalities deal with aging treatment systems, budget restrictions, and evolving compliance standards. As a result, water professionals need accurate and efficient tools to check water safety in the lab and in the field to determine levels of chemicals such as sodium, chloride, calcium, fluoride and ammonia, as well as pH, conductivity, and dissolved oxygen. By Dr. George Jarvis, Thermo Fisher Scientific, Water Analysis Instruments

  8. Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations
    6/21/2013

    Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.

  9. Understanding ISE Measurements In Wastewater Process Monitoring
    3/25/2013

    Analytic measuring technique provides a huge number of procedures to determine the concentrations of substances in an unknown sample, e.g. photometry, titration or mass spectrometry.

  10. How To Choose The Right Aeration Blower System For Your Wastewater Treatment Plant
    3/4/2013

    By comparing four types of aeration blowers designed specifically for wastewater treatment, this white paper educates engineers on how to develop a selection process best suited for their operation. The paper focuses on minimizing energy consumption and total cost of ownership of the aeration blower system. Download this white paper for a detailed comparison of real operating data on aeration blower technology.
