Wastewater Measurement Resources

  1. Math Solutions Explained: Biochemical Oxygen Demand (BOD) mg/L 8/23/2021

    Water Online’s “Math Solutions Explained” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), educates operators by explaining BOD mg/L calculations.

  2. The Transcend Design Generator Is Secretly An Advanced Data Analytics Software Package 8/9/2022

    The conceptual design output you get from the TDG will inherently have value -- the TDG already saved time and effort in creating the resulting conceptual design compared to traditional design approaches.

  3. Total Oxygen Demand (TOD) – An Alternative Parameter For Real-Time Monitoring Of Wastewater Organics 3/1/2015

    Today, due to the multitude of organics, the organic contamination of wastewater cannot be defined with passable analytical effort. Therefore, composite parameters become more important for the description of organic contamination. Parameters have been defined to enable a fast detection of organic loads.

  4. Los Angeles Department Of Water And Power Uses GIS To Improve Water Incident Management 12/3/2015

    While utilities use sophisticated systems to supply clean water as well as collect and treat wastewater, the effort to manage incidents and outages leaves room for improvement. Water utilities often rely on manual processes to handle customer reports of leaks, loss-of-service or quality issues.

  5. Automation 101: Open Loop Control 12/8/2014

    There is no argument that automation can be very expensive and that we have a fiduciary responsibility to our clients to provide the most economical solution possible. Every output, every input, every facet of your automation design will cost you something. There are no free rides, not even for us. But in our zest for cost savings, in our endless quest to make bricks without straw, we can quite easily short change ourselves.

  6. Engaging Stakeholders With Visualization And Analytics 11/24/2020

    The National Pollutant Discharge Elimination System (NPDES) permit program, created in 1972 by the Clean Water Act (CWA), helps address water pollution by regulating point sources that discharge pollutants into the waters of the United States.

  7. Point Level vs. Continuous Level Measuring Technologies 5/14/2018

    While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.

  8. Do I Really Need A New Flow Meter? 4/13/2015

    If you’re behind on flow meter technology, it’s understandable — wastewater monitoring and measurement devices have come a long way. Here’s your chance to catch up.

  9. Troubleshooting Nitrification And Denitrification In Wastewater 2/18/2014

    The proper tools are essential to fixing any problem. Over the years, Ohio EPA’s Compliance Assistance Unit (CAU) has helped dozens of water resource recovery facilities (WRRF) get back into and maintain compliance with NPDES discharge permits. Their field toolkit has included an assortment of batch sampling kits and handheld instruments. Each tool had its place but each also had limitations and, as a result, the compliance puzzle often was missing important pieces. Increasingly, as nutrient limits were incorporated into discharge permits, the missing piece was characterizing the dynamics of nitrification and denitrification. By Patrick Higgins

  10. SWAN Corner: How Artificial Intelligence Can Mitigate Water Workforce Issues 8/9/2021

    The loss of expert know-how, already a problem for years, has been made worse due to the pandemic. A network of expertise, optimized by artificial intelligence, may be the way to get ahead of the problem.
