    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...

    Accurate and Efficient Water Treatment Chlorine Analysis

    Chlorine is an important disinfectant whether used in swimming pools or the water that flows into our homes and businesses. For water treatment facilities, water treatment monitoring is one of the most important facility operations. Meeting regulatory requirements for residual chlorine is critical for public safety as well as for facility personnel. This 3-minute YouTube video, Enhance Chlorine Analysis to Reduce...

    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...
