WASTEWATER CASE STUDIES AND WHITEPAPERS
-
Video Case Study: SPIRALIFT® SR Provides Septage Receiving Solution
The Willits, California Wastewater Treatment Plant services over 10,000 residents and receives 750 loads of septage each year, but found they had a serious problem. Heavy septage from “honey trucks” was dumped by haulers into its wet well which clogged the plant’s pumps and caused flow channels to overrun. The plant also lacked oversight as to who was pumping and what was being pumped into its system. It could not control the pH level of the wastewater.

WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers
As with many plants modified for activated sludge treatment, the existing infrastructure at the Adams Field Wastewater Treatment Plant in Little Rock, AR, allowed rags and other debris to clog the impellers of the submersible pumps. One of the plant’s two 15-horsepower pumps was replaced with an 18-horsepower RAS submersible pump with a self-cleaning impeller, virtually eliminating the clogging problem by simply pumping away any debris that reaches the pump intakes.

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.

How To Save Time, Save Money With Pilot-Plant Testing
When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

Maximizing Your ROI On Test Equipment
In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company

Reducing And Reusing Water In Steel Manufacturing
The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

LATEST INSIGHTS ON WASTEWATER
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
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.

Ozone system performance hinges on reactor design, not generator size. Efficient mass transfer, hydraulic integrity, and contact time ensure consistent oxidation, reduced energy use, and reliable treatment results.
