The Many Faces Of SCADA By Christopher Little, Trihedral Engineering Limited
For over a decade, utilities have turned to supervisory control and data acquisition (SCADA) systems to monitor and control their re-mote infrastructure. In this article, operators discuss how they applied the benefits of SCADA to their emergency generators, wastewater treatment plants, potable water systems, and wind turbine farms.
Troubleshooting Nitrification And Denitrification In Wastewater By Patrick Higgins, YSI, a Xylem Brand
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.
Turbiwell Quarterly Calibrated Unit Vs. Quarterly Verified Unit By Shaun Sharrett and Randy Turner, Swan Analytical USA
This paper presents the field data collected over a twelve-month period at a municipal surface water treatment plant employing traditional clarification and filtration. The final effluent turbidity was monitored by the third-party compliance turbidimeter, a Swan Turbiwell (Protocol Turbiwell) that was calibrated quarterly just as the compliance turbidimeter, and a second Swan Turbiwell (Nonprotocol Turbiwell) that was not calibrated.
Versatility Of Thermal Mass Flow Meters By Magnetrol International
There are many well-documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol Thermatel TA2, are a rapidly growing technology that is continuously evolving.
The City of Grand Rapids WWTP reduced their aeration costs by 15% and received a $58,728 rebate check from the local energy utility after installing a Real-Time Control System for Nitrification. Download the application article to learn how they did it.
