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.
Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own purposes.
Tough-to-access submersible pumps complicated life and increased costs for maintenance workers at the Royal Cornwall Hospital in Truro, United Kingdom.
Water’s high heat capacity, high thermal conductivity, and historically low cost make it popular for process heat exchange. Power plants, especially those for liquid cooling applications, withdraw a large fraction of the total demand for water necessary for agriculture, industry, recreation, hygiene, drinking, and wildlife. By Kevin J. Farrell and Vijay Sathyamurthi, Heat Transfer Research, Inc., College Station, Texas USA
A pharmaceutical manufacturing plant located in Sedom, Israel faced challenging environmental conditions including low humidity, temperatures exceeding 105 degrees Fahrenheit and limited water supplies.
Veolia entered into a DBO contract with a mining company for its mine water treatment facilities. Veolia designed and built a 3,500-gpm centralized Zero Liquid Waste (ZLW) system using advanced treatment technologies.
There has been a growing need in the marine industry for accurate flow measurement of fuel aboard ships.
After an international tender process, the Israel Electric Company (IEC) chose Fluence to design, manufacture, and supply containerized ultrapure water production systems for use as makeup water for heat-recovery steam generators (HRSG) and for NOx emission reduction at recently upgraded power plants across Israel. More than 15 units of 20 m3/h production modules, each fitted in two 40-foot shipping containers, were provided to seven power plants. Their compact design allowed for ease of installation, operation, and maintenance while meeting the customer’s demanding engineering standards.
With relatively predictable flow patterns, municipal wastewater treatment plants (WWTPs) are conditioned to respond to the ebb and flow of demands with a series of small tweaks. While industrial wastewater processing does not always enjoy the same advantage of predictability, continuous monitoring of processes and wastewater output does offer opportunities for more responsive, more precise control.
Although by no means overwhelming, clogging problems in a county prison wastewater treatment system had simply become a nuisance, and it was time to take action with new technology to solve the problem. Read the full case study to learn more.

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).
We’re past the midpoint of the Texas legislative session and the bill filing deadline is behind us. Because the legislature only meets for five months every other year, there’s a lot to accomplish in a short span.
Circular economy approaches can add value to a vast range of processes and product sectors, but water is the ‘blue thread’ that flows through it all, Nick Jeffries tells Paul O’Callaghan, chief executive, BlueTech Research.
Thist article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.
Texas is sizable enough to be a large country on its own, with an economy to match, and is also proudly unique. But when it comes to water issues, the Lone Star State shares a lot in common with the rest of America: overwhelmed and vulnerable infrastructure, threats to water quality and security, and competition for resources.
U.S. and Canada industrial sector withdrawals have declined 30 percent over the last three decades to 152 BGD. This trend, which is expected to continue, has been sparked by water-related technology improvements at facilities, company strategies to mitigate water supply risks, and outside pressure to better manage wastewater effluent through regulations and rising discharge costs.
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.
As industrial facilities continually look for ways to reduce capital costs and decrease installation timelines associated with water treatment and other systems, the practice of containerizing equipment has become more prevalent. A containerized system offers many benefits of lower costs than comparable field erected buildings, faster timelines, and lower field installation requirements.
There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use for billing or internal accounting purposes in such ad hoc applications.
The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.
