Energy Management with IIoT for Water and Wastewater Utilities
Peter Gabor Water & wastewater utilities can improve efficiency using Industrial Internet of Things (IIoT) technologies. In a WaterWorld article, Leveraging IIoT for Energy Management , Emerson’s Peter Gabor participated in a question & answer session to share his thoughts on how these utilities are incorporating IIoT. Peter noted that energy costs are a big part of total operating costs and driving down energy consumption...

Monitoring Hydrogen Sulfide for Personnel Safety
Deadly hydrogen sulfide (H₂S) can be present in industries such as oil & gas production and wastewater treatment. The Wikipedia Hydrogen Sulfide page highlights the danger: Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis , degeneration of the basal...

Weathering the Storm: Equipping Wastewater Treatment Plants with Flood-Proof Actuators
Author: Steve Poling As we approach the 6 th anniversary of Hurricane Sandy and just passing the 1 st anniversary of Hurricane Harvey, the anxieties of facing another superstorm weighs on the minds of every coastal wastewater treatment operator. And with Hurricane Florence approaching the U.S. Carolinas , this string of major storms continues. Are we prepared? By design, most wastewater facilities are in low...

Handling Processes with Long Lag Times
Emerson’s Mircea Lupu shared his thoughts on Ovation system algorithms for handling processes with long lag times—a control challenge that vexes many. Mircea opened noting that control algorithms are at the heart of any control system to provide stable and accurate response and robustness against disturbances and process changes. Tuning these algorithms to achieve the desired performance can be laborious. Proportional...

Improving Control System Alarm Effectiveness for Operators
During the week of July 29 through August 3, I’ll be attending the Ovation Users’ Group Conference in Pittsburgh. This users’ group is composed of people working in the power, water and wastewater industries. If you’re in one of these industries and an Ovation distributed control system user, I look forward to seeing you there. One of the critical parts of an effective control strategy is to get the alarm design right...

Point and Continuous Level Measurement in Water and Wastewater Applications
Across many industries, level measurements are critical ones for safe and reliable operations. This is true for the water and wastewater industries. The choice of technologies for these measurements is broad, especially since they fall into two categories point-based (on/off switching) and continuous. In a Water Online article, Point Versus Continuous Level Measuring Technologies , Emerson’s Lydia Miller provides...

Suite of Cybersecurity Technologies and Practices
Emerson’s Adam Boeckmann presented the Power and Water Cybersecurity Suite at the 2017 Ovation Users Group conference. He opened describing the team that formed over the last several years that now supports more than 200 sites in the U.S. alone. He shared the story of the recent Wannacry/WannaCrypt ransomware cyber-attack. In March of 2017, Microsoft released a patch. A month later, the National Security Agency (NSA...

Comprehensive Cybersecurity for Critical Infrastructure
The electrical power generation and distribution industries, especially here in the U.S., have a long history in working to improve reliability and security. This history goes back to the establishment of the North American Electric Reliability Council (NERC) in the late 1960s as a response to a widespread blackout in the Northeastern U.S. NERC became the North American Electric Reliability Corporation (also NERC...
