• Employing Wastewater Testing To Monitor Infection Trends And Control The Spread Of COVID-19

  Since March of last year, when the World Health Organization (WHO) declared COVID-19 a global pandemic, the U.S. has recorded over 33.7 million cases of infection and surpassed 600,000 deaths due to the highly transmissible viral disease.

• Hydroinformatics 101: Intro To Water Optimization And Efficiency

  Hydroinformatics offers a fresh perspective that is enabling communities around the world to tackle ageold problems in new ways and with a bigger toolset.

• Integrating Safety And Process Environments

  Using a single programmable controller such as Schneider Electric’s M580 Safety Controller to manage both process and safety systems can help speed up deployment, improve reliability and sustainability of operations, enhance cybersecurity, and support greater productivity and transparency.

• SWAN Corner: Wet Weather Measurement Means More Than Scratching The Surface

  Wet weather is a continuous concern for wastewater utilities. Rain-derived infiltration and inflow (RDII) challenges the collection system capacity. It can potentially result in overflows in the collection system and even the wastewater recovery facility (WRF) in extreme cases. These overflows can threaten public health and the environment. Additionally, higher flow volumes associated with wet weather will increase operating costs at the WRF.

• SWAN Corner: How Regulators And Innovators Are Working Together To Digitize Wastewater Regulations

  Advanced technologies have been trickling into wastewater processes for the last decade, but only recently have bodies such as the International Standards Organisation added smart systems to their list of standardised practices. Collaborations with tech startups have played a vital role in bringing standards in line with current technological capabilities, but there’s a long way to go...

• High-Precision Non-Invasive Temperature Measurement

  This white paper presents ABB’s new TSP341-N temperature sensor for non-invasive temperature measurement and provides examples for applications and accuracies that can be achieved. The present Edition II of the whitepaper additionally presents the results of a direct comparison of non-invasive temperature measurements with classic measurements in a measuring medium, achieved in realistic conditions. These results emphasize the outstanding suitability of the device for multiple applications.

• From The 1970s To Today – 4 Key Advances In Coriolis Flow Measurement

  Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.

• City Of Decatur Implements Siemens SITRANS store IQ For Operational Transparency

  The City of Decatur Wastewater Treatment plant in Texas includes a polishing pond and effluent discharge basin, both of which can be overcome with algae growth depending on weather and environmental conditions throughout the year. At times, the algae overgrowth would plug areas of these systems and restrict or block the flow from the polishing pond and effluent basin, which sit approximately 300 yards from each other.

• How Modern Ultrasonic Controllers Can Help Water Utilities Save On Energy

  In industry today, everyone is looking for ways to conserve a bit of energy and save some money. For instance, consider the energy consumption across the United States just in the water treatment process. With thousands of public water utilities, the amount of energy usage is significant.

• How To Do Level Monitoring Better

  Existing level monitoring, usually for combined sewer overflow (CSO) or event duration monitoring (EDM) purposes has been in regular use in the U.K. for over a decade, but the equipment hasn’t changed much in that time. With the current technology comes limitations. So, the question Dave Walker, co-founder and commercial director at wastewater monitoring specialists Detectronic, has been asking is: How can we do level monitoring better for the benefit of water companies, their customers, and the environment?
