Wastewater Measurement White Papers and Case Studies

  1. Why A Little Knowledge About Sensors Can Be A Dangerous Thing
    6/4/2014

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  2. Low-Cost Computational Fluid Dynamics Modeling For Pump Stations
    11/22/2013

    Avoid pump station failures, protect the environment, and save money through computer simulation.

  3. 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.

  4. Tracking Chemical Use To Optimize Quality, While Saving Money
    8/24/2017

    What technology is available to monitor and optimize my plant operations?

  5. Water Treatment for Industrial Reuse
    11/5/2014

    By making hypochlorite solution only as needed, the compact Constant Chlor unit brings efficiency, consistency to water reuse system.

  6. Flow Data Red Flags: When To Act
    12/20/2017

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  7. The Full SCADA Deal: The Benefits Of Adopting A Complete SCADA System Over A Sophisticated RTU-Based Solution
    5/14/2014

    For over a decade, The Bahamas Water and Sewerage Company (BWSC) faced significant service challenges on the Island of New Providence. These included a lack of centralized monitoring and control for the island’s primary water treatment and distribution system, as well as limited reporting, alarming and remote access.

  8. Application Note: The Ultrameter II™ In Municipal Wastewater Treatment
    3/9/2009

    Publicly Owned Treatment Works (POTWs) are faced with the challenge of processing the effluent wastes of multiple sources: residential, industrial, and environmental. Under laws governing pretreatment, the ultimate responsibility in determining whether or not industrial effluent meets criteria for treatment belongs to the POTW. Once the POTW has the effluent waste within the confines of its treatment facility, it is accountable to the federal, state, and local regulations governing the quality of the wastewater it discharges into lakes and streams or injects underground.

  9. How To Apply And Maintain A Photometric/Colorimetric Analyzer
    5/21/2018

    Water resource recovery (WRR) plants must monitor ammonium and orthophosphate. Permitted levels for these nutrients in effluent discharge are becoming increasingly tight because state environmental agencies and the U.S. Environmental Protection Agency (EPA) are requiring dischargers to reduce the amount of nutrients in their effluent.

  10. Optimize Process Unit Results With Advanced Analytics For Condition-Based Monitoring
    1/3/2019

    Businesses rely on process units meeting or exceeding their operational plans. To ensure that operational plans are achieved, it is important that equipment operates as designed (i.e., delivers the required performance) and continues to operate in an optimum manner (i.e., remains reliable, in a good condition). The most common causes of missing operational plan targets are equipment failure, which results in unplanned downtime, and low quality or yields from production processes.
