The Challenge Of Flow Disturbances On Meter Accuracy
Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.

How To Utilize pH Neutralization Systems And Adhere To Discharge Regulations
For any drinking water or wastewater treatment operation, pH neutralization is never far from top-of-mind. The regulatory standards for pH to which effluent must adhere, also known as “pH neutralization,” are central to ensuring that treatment is performed accurately and that the water or wastewater leaving a plant is safe.

The Evolution Of Collector Monitoring Systems
The vast majority of chain and flight collectors in operation throughout the world do not have any form of monitoring system installed to protect against operational failure. Traditional safety devices consist of a shear pin sprocket device, with a limit switch, designed to protect the drive system if a load or torque exceeds the working load of the drive chain; in the event that this occurs, the shear pin will break, the limit switch will be activated, and the drive motor is shut down. This process will typically protect the drive chain and drive motor from failure. When the shear pin breaks, the clarifier is drained, the cause of the overload is established and corrected, a new shear pin is installed, and the collector is placed back in operation.

AquaSBR® Replaces 60-Year-Old Treatment Plant
The Moab Water Reclamation Facility (WRF) was initially constructed in the late 1950’s to provide primary treatment of domestic wastewater for the Moab area. However, the plant could no longer keep up with the higher flows and loading due to population growth and rising tourism. In addition, with aging infrastructure and the new permit cycle in sight, upgrades to the biological treatment were necessary to ensure full compliance. Read the full case study to learn more.

When To Consider An Alternative To Thermal Dispersion Meters
Maintaining a firm grip on blower output within digesters at wastewater treatment plants is the key to stable dissolved oxygen levels that support an optimal biological cycle. However, the most common type of device used to measure aeration in the activated sludge process — thermal dispersion flow meters — is not always the best fit. The good news is that wastewater plant operators have multiple alternatives.

LATEST INSIGHTS ON WASTEWATER

Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
