WASTEWATER MEASUREMENT RESOURCES

• Troubleshooting Nitrification And Denitrification In Wastewater

  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

• High Availability, Connected Control Solution Virtually Eliminates Downtime

  Mekorot, Israel sought to reduce production costs through improved energy efficiency and tighter process control. They leveraged GE Digital's software and automation solutions to automatically monitor and control devices. 

• Why A Little Knowledge About Sensors Can Be A Dangerous Thing

  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.

• Machine Learning And The Future Of Water Quality Monitoring

  Aided by "soft sensors," machine learning is revolutionizing monitoring and powering real-time predictions.

• Hydraulic Modelling Provides Long-Term Simulation Scenarios, Compelling Visual Results And Accurate Flow Assessments

  Wastewater plant managers in Texas needed a solution to ensure their facilities could maintain water flows running at their current capacity. 

• How Can The Water Industry Benefit From IoT Technology?

  The technology of the Internet of Things (IoT) has been a pioneer in developing solutions that are rich in monitoring, analytical, and automation features. These innovative features allow the industry to optimize operational methodologies, boost overall equipment effectiveness, and automate processes that are generally performed manually.

• Smooth Sailing At Bloomington/Normal Southeast Wastewater Treatment Plant

  When the Bloomington-Normal Southeast Wastewater Treatment Plant won a 2018 Plant of the Year award from the Illinois Association of Water Pollution Control Operators, team members were ecstatic. Randy Stein, executive director and sports fan, likened it to winning the “Stanley Cup of wastewater.” On its way to the award (in Group 1 for plants larger than 7.5 mgd), the plant racked up 12 consecutive Gold Peak Performance Awards from the National Association of Clean Water Agencies. 

• UV Treatment Upgrades In Wales

  In order to improve the treatment performance (because of the continued cost to maintain compliance), and ensure that it would eventually have the treatment capacity to meet future population growth equivalent of up to 225,000, Swansea WwTW was in need of an equipment upgrade.

• Helping Detroit Get The Lead Out

  Learn how the Kresge Foundation promotes efficient and equitable lead abatement efforts by supporting the use of BlueConduit's machine learning technology. 

• WWEMA Window: 3-D Imagery As A Workforce Recruitment Tool

  Why does our industry not seem to attract both a large number and highly skilled new talent like other industries do? I contend that as an industry we must do everything possible to sell ourselves and the important mission we fulfill, and what better way to do this than to wave the technology flag?
