WASTEWATER MEASUREMENT RESOURCES

• Measuring Organic Load: Is BOD Still A Relevant Measure In The Modern Water Industry?

  Biochemical oxygen demand, or BOD, is probably one of the most- and least-known parameters in the wastewater industry.

• Math Solutions Explained: Biochemical Oxygen Demand (BOD) mg/L

  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.

• Continuous Monitoring And Control System Improves Communication, Operating Efficiency

  In the early 1990s, the Borough of Ridgway purchased several separate systems to control their water treatment and five bay filtration processes. Through the years, technology obsolescence led to difficulties in obtaining support and spare parts for all the systems. At one point, the existing systems completely failed, leaving Ridgway employees to manually operate the plant for several months. A new, more efficient system was desperately needed.

• COVID-19 And Wastewater Utilities

  Today, the world is facing unprecedented circumstances that are affecting every single sector and the water service is no exception. Although there is still more research to be done, this article has collected the currently available information to highlight how wastewater utilities have been affected by the COVID-19 pandemic. More specifically, this article will attempt to look at the outbreak’s impact on utilities, the potential hazards, and the predominant solution.

• IoT Cellular Connectivity For Optimizing Water Utilities Management

  Digital transformation allows utilities to go from data drought (and actual drought) to a deluge of efficiency, but security is paramount.

• Pollution Early-Warning Technology Chosen By Anglian Water

  Anglian Water has become the first utility to adopt new cloud-based technology to detect rising main sewer bursts. The UK utility is implementing early-warning system BurstDetect, as part of its drive to eliminate serious pollution events in its region by 2025.

• Midwestern Utility Takes Data Collection From Manual To Automatic

  Read how a publicly owned electric, gas, and water utility taps FreeWave Technologies for new connectivity and edge data collection solution, and achieves immediate, significant results. 

• Amazing And Reliable Insights Gathered From Dissolved Oxygen Sensors

  Dissolved oxygen sensor monitoring is critical to making wastewater plants run smoothly and within regulations. Here are some fascinating things people can learn by looking at data from these devices.

• City Solves Reliability And Maintenance Problems For WTP Hypo Feeds

  A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.

• City Of Shelby, Ohio WWTP Eliminates CSOs While Upgrading To A State-Of-The-Art Facility

  The City of Shelby, Ohio recently upgraded its activated-sludge wastewater treatment plant to double its capacity to 5 MGD, while expanding its capability to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions.
