  1. Understanding The Changes To CWA Test Procedures 1/19/2017

    The U.S. EPA has updated the list of approved test procedures that can be used to analyze wastewater for compliance under the Clean Water Act.

  2. What Is Adenosine Triphosphate (ATP) And What Does It Do? 12/5/2016

    Many people know what ATP stands for, but do you know what it does? This article demystifies this amazing energy carrier and explains why water professionals should care about it.

  3. DNA Sequencing: The Future Of Water And Wastewater Analysis? 11/16/2016

    DNA sequencing can provide more information on water and wastewater than traditional methods. Is it time for treatment operations to adopt the method?

  4. Math Solutions: Alkalinity Calculations 11/2/2016

    We know the importance of pH to biological wastewater treatment, but alkalinity should be considered equally important for its direct correlation to pH.

  5. Top 10 Technologies From WEFTEC 2016 10/25/2016

    300,000 square feet. That was the size of the tradeshow floor at WEFTEC, the world's largest annual water quality exhibition. I didn't see every technology showcased last month in New Orleans (over a thousand exhibitors were on hand), but here’s a “best of” list from the many that I came across — a snapshot of various technologies that stood out from the masses, exceptional for their level of innovation and potential for industry impact.

  6. Math Solutions: Mixed Liquor Volatile Suspended Solids (MLVSS) Calculations 10/4/2016

    Wastewater consultant and trainer Dan Theobald (“Wastewater Dan”) dives deeper into the activated sludge process with calculations focused on MLVSS.

  7. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China 6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  8. Carbon Dioxide For pH Control Of Landfill Leachate 6/16/2016

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  9. Protecting Against Doomsday Contaminants 5/16/2016

    New tools are being developed for worst-case drinking water scenarios: chemical, biological, radiological, and nuclear (CBRN)-related contamination.

  10. Is Water 4.0 The Future? 4/21/2016

    Water 4.0 is a concept that has recently been raised as the “future” of the water industry …possibly. Apart from being a paraphrase of Industry 4.0, the questions have to be asked: What is it, and what does it have to do with the way the water industry operates in its current state?
