Using a technology called SmartCover Systems, the Prince William County Service Authority is able to remotely monitor wastewater flows in strategic areas across Prince William County. A SmartCover is comprised of a small device that electronically monitors the level of flow in sewer mains from the underside of a manhole cover.
The question of how to get the most out of the data that we collect as an industry was central to the Sensing in Water Conference recently hosted by the Sensors for Water Interest Group (SWIG). The two-day conference highlighted several themes on how to get the best of the data that the Water Industry collects and how to make our measurements “meaningful.” Chief among those themes was greater collaboration among the different stakeholders, including water companies, universities, and the supply chain.
Understanding your detection needs when it comes to free cyanide can help you choose the most suitable detection method.
For the second straight year, the Water Environment Federation Exhibition and Conference (WEFTEC) came to McCormick Place in Chicago, returning also to the city which launched WEFTEC 90 years ago. As always, it was a showcase of the latest technologies and ideas available in the water/wastewater industry, but each show also has its own "feel" that reflects the times.
Rapid industrialization and tightened water quality standards are leading to an increase in global spending on water quality monitoring instrumentation. Spending in this area is projected to grow from $2.5 billion in 2014 to $3.6 billion by 2020, with some 25 percent spent on new, less expensive water quality monitoring sensors that deliver on-the-spot measurements.
High up in the Tehachapi Mountains of California’s Central Valley lies the largest consumer of the state’s electricity, driving 14 centrifugal pumps, each rated at 80,000 hp.
A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.
Kansas City’s Smart Sewer program represents the nation’s first federal consent decree to include green infrastructure solutions in the reduction of wastewater overflows, as well as the city’s largest infrastructure investment to date. Projects that include the words “first” and “largest” do not come along without the strong leadership of a “Water Champion” such as Special Assistant City Manager Andy Shively, PE, who shares his experience and expertise in this Q&A.
Water utilities are tasked with ensuring a sustainable and safe supply in addition to achieving business and service excellence goals. These goals are typically based on criteria that measure operational performance, meeting bond covenants, and customer satisfaction.
Activated sludge has been a cornerstone of wastewater treatment since the early 1900s. Over the years, variations of the activated sludge treatment process have surfaced. These variants were efforts to improve treatment performance or reduce capital or operating costs. A new technology, known as Nereda®, uses aerobic granular sludge to meet all those criteria.
