11.11.21 -- New Lead-Contamination Ground Zero; Digital Twin At A 45-Year-Old WWTP

The V-Cone is widely known for its success as a metering solution in the oil and gas industry, but it’s also a burgeoning solution for many industrial applications, including district steam. The V-Cone’s tolerance for a range of flow conditions and media, as well as available customization, makes it a viable, lasting solution for many unique new and retrofit steam applications.

In many applications, higher-accuracy measurements are required to protect the customer from over-billing and the supplier from under-billing. Common products requiring this level of accuracy are typically oils, fuels, edible oils, and alcohols. In the oil and gas industry, this requires a system called automatic tank gauging (ATG) as defined by the American Petroleum Institute (API) standards.

The United Nation’s (UN) World Water Development Report recently stated that nearly six billion people will suffer from clean water scarcity by 2050. Singapore is using desalination as part of the solution to their water supply issue in order to provide enough clean drinking water for its ever-growing population of 5.5 million.

Plant officials at a 12 MGD wastewater plant in Arkansas began evaluating disinfection alternatives to upgrade their current system as well as address the removal of contaminants of emerging concern (CEC). The facility, which included primary clarification, activated sludge, secondary clarification, and sand filtration, elected to use dissolved ozone to replace its current ultraviolet (UV) system. 

Fairfield Wastewater Treatment Plant, in Butler County, OH, was having a lot of trouble with their grinders. The plant serves over 42,500 domestic customers and several commercial and industrial institutions, as well as Mercy Hospital of Fairfield. They treat about five million gallons of wastewater collected in over 175 miles of sewer pipe each day.

In clean water pumping applications that experience variable demands throughout the day, efficiently sizing and running pumps through their daily cycle requires a delicate balance in process design. Variable frequency drives (VFDs) are a valuable tool for matching pump output and energy consumption closer to actual demand. Here are some important points for evaluating and choosing the best VFD solutions.

Reverse osmosis (RO) has become a widely utilized treatment process for diverse applications such as medical and laboratory research, desalination, and treatment of industrial wastewater and municipal water/wastewater. Because of its widespread use and technically advanced nature, a variety of quality parameters should be monitored by those treatment operators who utilize it.

To save money and protect the environment, municipal water systems are increasingly under pressure to adopt sustainable practices. However, progress in this area is often hampered by a wide array of issues. As an alternative to traditional valves, the use of valve insertions has emerged as a sustainable maintenance solution.

While the ‘digital twin’ concept has been around for several decades, most of the talk about it in water and wastewater treatment has focused on using it to monitor and manage active operations. Yet the same logic and capabilities also hold promise for plant operators and their consulting engineers in terms of evaluating key technology decisions on designs for new or upgraded plant processes.
