For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
People enjoy their water in Lynchburg, Virginia. The city of nearly 80,000 is next to the James River, which residents use for boating, swimming, and fishing. Meanwhile, the City of Lynchburg Department of Water Resources is hard at work providing water, waste water, and storm water service to the community. The department uses innovative technologies to improve its efficiency — including Ignition by Inductive Automation®. Ignition is an industrial application platform with tools for building solutions in human-machine interface (HMI) and supervisory control and data acquisition (SCADA).
As our society continues to embrace digital technology, it’s fair to say that the world of water utilities will be, a major beneficiary of this revolution.
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
There is little doubt about the importance of taking turbidity readings as part of drinking water treatment. However, there are certain misperceptions about the associated requirements and procedures needed to confirm the validity of those readings. The major points of confusion seem to revolve around perception of the terms “approved,” “calibration,” and “validation.” Here is a quick synopsis on what you really need to know about meeting U.S. EPA Method 180.1: Determination of Turbidity by Nephelometry for accurate turbidity readings.
One of the trends in water and wastewater treatment over the past decade has been a growing demand for decentralized systems. Water Talk recently caught up with Nii Mensah, General Manager of Fluence USA, to learn more about the solutions that the new company (formed by the merger of RWL Water and Emefcy) is bringing to market to address communities’ treatment needs
Norfolk Southern has a history of nearly two centuries of service that has linked communities and customers to the marketplace of the world. The railway company operates approximately 20,000 miles of rails and serves every major container port in the eastern United States while providing connections to other rail carriers.
Fluence’s first MABR plant in mainland U.S. gives California new medium- and small-scale treatment options that comply with the state’s stringent standards for water reuse
Operational savings realized through high-tech leak detection techniques could pay for your utility’s advanced leak detection equipment.
Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year of specified GHG’s to provide an annual report of their actual GHG emissions.
