• 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.

• Top Three Water System Inefficiencies You Can Address Today With Better Insights From Your Data

  As utilities continue to innovate and pursue the digitalization of water distribution and wastewater systems, new water tech can lead the way in addressing operational inefficiencies.

• Water Stewardship- Because Everyone Is A Water Manager

  Smart water technology has evolved the water utility’s role within municipalities to have a seat at the proverbial Smart City table, participate in the IoT plan, and drive water stewardship. There are many benefits to replacing your meter system with AMI (Advanced Meter Infrastructure) technology. For the utility, the game-changer is when you couple it with meter data management software which streamlines and prioritizes data so you can make timely, informed decisions.

• The 4 Pillars Of Control Room Operator Effectiveness

  With more water and wastewater utilities, as well as industrial facilities, moving toward digitalization, it’s important to understand the needs of data gatekeepers and decision-makers to set them up for success.

• Tackling Modern Wastewater Treatment Challenges And Unlocking Efficiencies With Advanced Water Technologies

  Research studies, empirical evidence, and the march of time all suggest that the implementation of next-generation technologies at wastewater utilities is profoundly important, if not imperative, for efficient operations.

• Carbon Dioxide For pH Control Of Landfill Leachate

  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.

• Advanced Diagnostics of Thermal Mass Flow Meters

  Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.

• Innovative, Collaborative, Inevitable: Furthering The Evolution Of Smart Water In North America

  A Q&A with Gary Wong, chairman of the SWAN North American Alliance

• Math Solutions: Mixed Liquor Volatile Suspended Solids (MLVSS) Calculations

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

• The Role Of IoT And Control Technologies In Water Filtration Systems

  With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.
