The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.
Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.
The impact of utility industry restructuring is being felt on several levels. The upside of distributed generation growth and the diversification of power sources are also resulting in the downside of loading issues, less switching flexibility and the potential for reverse power flow. New predictive asset analytics tools allow utility personnel to address these issues before they become problems. This paper reviews how these tools can be applied to both utility operations and maintenance.
In municipal or industrial wastewater treatment applications, steel constructed tanks up to 5.0 million gallons per day (MGD) and below offer significant advantages over concrete; benefits that lead to lower operating and lifetime costs, regardless of application.

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.
The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.

As we celebrate Smart Irrigation Month, it's a great time to highlight not only smart technologies, but the smart people and smart decisions behind them. One remarkably smart tool that ties all three of those elements together is the Irrigation Consumer Bill of Rights by Dr. Charles Burt of the Irrigation Training and Research Center (ITRC) at the California Polytechnic State University (Cal Poly) in San Luis Obispo.
Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.
To ensure informed chemical safety decisions can be made about thousands of chemicals, scientists and decision makers need a constantly evolving set of tools for quickly and efficiently evaluating chemicals of interest. EPA scientists have recently released an update to the online Computational Toxicology (CompTox) Chemicals Dashboard to help advance these efforts. The website has been updated with new data and functionality every six months for the past three years.
Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.
Collaborative research is a critical element for identifying unforeseen risks associated with using the oil industry’s wastewater outside the oilfield. That’s the recommendation of a new peer-reviewed paper accepted this week in the Journal of Integrated Environmental Assessment and Management (IEAM).
