Wastewater Instrumentation White Papers & Case Studies

  1. 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

  2. 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

  3. 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.

  4. 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.

  5. 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

  6. 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.

  7. 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.

  8. 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. 

  9. Low WWTP Operating Costs And High Water Quality -- It's Possible
    2/13/2013

    Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. By Patrick Higgins

  10. New Luminescent Technology Brings Faster, More Accurate CBOD Analysis
    2/4/2013

    Measuring DO in the CBOD procedure was once troublesome and inefficient for lab personnel and operators alike at the Southside Wastewater Treatment Plant in Tyler, Texas. But all that changed when they adopted new luminescent technology that has eliminated problems with instrument drift, slow measurements, and frequent maintenance.
