WASTEWATER MEASUREMENT RESOURCES

  • 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

  • In 2020 SUEZ initiated a project called SPOT 2023 focused on reducing operational costs with in SUEZ-operated utilities across the world Optimizer was identified as a viable tool that could potentially help to achieve the objective of this project. To investigate this further, Optimatics and SUEZ ran a pilot project study, using the water distribution network in Cartagena, Colombia.

  • Remote wastewater services are available to monitor e-waste contamination in the global water supply. This article explains the problem, details its scope and threat, and presents devices for the monitoring of e-waste in water.
  • When people talk about artificial intelligence, they tend to sort into four camps — doomers, gloomers, bloomers, and zoomers. The doomers fear the robot apocalypse. The gloomers worry AI will automate away all the meaningful jobs. The bloomers are optimistic about AI innovation but want to take a measured approach with guardrails as the technology develops. And the zoomers? They're already deep into it and want minimal regulation to accelerate progress. But I'd like to add a fifth mindset to the mix: the loomers.

  •  In the level measurement world, there is a rivalry between the two most commonly used measurement instruments: ultrasonic, which uses sound-based measurement, and radar, which uses high-frequency electromagnetic waves to determine distance.

  • The city of Baltimore uses a collection system hydraulic model to address asset management issues and improve sewer, stormwater and flood mitigation. This client was able to resolve critical challenges using the latest modeling software. 

  • 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.

  • A mid-size water system in the southeast was looking to pull together multiple measurements in a single panel. After reviewing off-the-shelf solutions, they realized there was nothing that met their requirements.

  • Serving an area from eastern San Marcos to northwest Seguin, Crystal Clear Water Supply Corporation (CCWSC) recently commissioned their integrator, Central Texas Water Maintenance (CTWM) to replace their Wonderware and WIN-911 systems with VTScada software from Trihedral.

  • Water utilities of all sizes face daunting challenges.  Small utilities face the same challenges as large utilities, but have to do more with less.

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.
