WASTEWATER MEASUREMENT RESOURCES

  • 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.

  • The water industry's greatest technology trend is also one with scattershot levels of adoption, but that can change with proper understanding of the purpose for and pathway toward Digital Water.
  • The COVID-19 pandemic has rewritten the way businesses and organizations operate and serve their customers, and utility districts are no exception. White House Utility District (WHUD), Tennessee's largest water and wastewater provider in terms of geographic area served, is a case in point.

  • 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

  • This paper discusses how the right combination of digital tools is helping cities move from a reactive response to delivering a more sustainable future while saving costs and connecting the workforce to trusted data.

  • They did it again. Seemingly every year WEFTEC breaks records for size and attendance, and 2014 in New Orleans was no exception. There was a lot to choose from, but I picked my favorite innovations to highlight in what has become another annual tradition — Water Online’s “Top 10” from WEFTEC.

  • Padre Dam Municipal Water District provides water, wastewater, recycled water, and park and recreation services to over 102,000 residents in East San Diego County in California. Padre Dam's infrastructure is worth over $700 million, and it has an annual budget of $76.3 million. Padre Dam imports 100 percent of its drinking water supply and treats two million gallons per day (MGD) of wastewater at the Ray Stoyer Water Recycling Facility.

  • The City of Henderson engaged Stantec and Optimatics to develop a new master plan for their water distribution system, in preparation for the expected population growth and demand increase in the coming years. This optimization effort aimed to determine the lowest cost master plan strategy that satisfied the City’s hydraulic design standards, based on forecast 2050 demands Prior to optimization, the City and Stantec had identified a range of possible project sites, so the optimization was largely focused on determining which of these projects to complete, as well as how to size them.

  • InfoWorks ICM 2021.6 is the fifth installment of new and improved features being brought to the storm, sewer and flood industry this year!

  • Treatment plant control systems are more vulnerable to computer hacks than ever before. What should utilities be doing to prepare themselves?

WASTEWATER MEASUREMENT SOLUTIONS

  • Group 31 Quarter-Turn Compact Rotary Actuators

    Group 31 compact rotary actuators, model 31-M50, include a single analog electronic control module which receives a 4–20 mA or 1–5 V dc input signal and provides a 4–20 mA or 1–5 V dc feedback for position control and indication.

  • Group 75 Compact Rotary Actuators

    These compact rotary actuators were originally designed to control boiler windbox damper applications. Today they are used in numerous ways. Constructed with multiple mounting points makes it flexible to fit into tight areas. Great for controlling small rotary valves and damper applications. The model 75 actuators adapt to challenging heat and space configurations that other actuators cannot accommodate.

  • Multi-Turn Actuator (88-109)

    The Beck 88-109 is a continuous duty, multi-turn actuator designed to provide reliable control of rising stem and non-rising stem gate valves. Additionally, when coupled with a 1/4-turn gearbox, it is an ideal solution for large butterfly and other quarter-turn valves with high torque requirements.

  • Panametrics Achieves Challenging Wastewater Flow Measurement On A Lined Ductile Iron Pipe

    A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

  • Cleaner Water With Liquid Ai™

    Every time we open a tap, we trust the water is safe to use. It is easy to forget that we only enjoy this luxury because of monitoring systems, tirelessly working in the background and warning water companies of every anomaly. Likewise, wastewater also needs to be continuously monitored to avoid pollution.

WASTEWATER MEASUREMENT VIDEOS

In this episode of The Water Online Show, host Angela Godwin sits down with Mike Saunders from ORENCO to explore how a small Oregon startup founded in a garage grew into an industry leader redefining decentralized wastewater solutions.
