WASTEWATER CASE STUDIES AND WHITEPAPERS

I-BOx® 6000 Biological Odor Control System Removes Odors From Laguna SOCWA Lift Station
After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.

Blower System Integration For Wastewater Aeration Applications
The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

What Is The Impact Of Climate Change On Stormwater Modeling, And How Can Water Professionals Prepare?
As the world’s climate continues to shift, the effects of extreme weather events are beginning to cascade through the modern civilized world. While topical discussions of the impacts of climate change often focus on significant natural disasters, there are other more gradual impacts to the way the world works that this shifting climate brings.

SPIRALIFT® Screening System- Solves Sludge And BOD Problems At City Of Plymouth
The City of Plymouth processes 150,000 gallons of raw sewage a day. Before 2009, the plant had no headworks installed at all. The raw sewage was being dumped into a pond. Because of this, the plant suffered major ongoing sludge and BOD problems. A city engineer recommended a new system be installed to combat these problems. After doing research, the engineer found a Franklin Miller system that proved a perfect solution.

Biologically Active Filter Technology Applications For Wastewater Treatment Upgrade
Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading to tertiary treatment and the removal of BOD, TSS and Total Nitrogen.

Advances In Paper-Based Devices For Water Quality Analysis
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

LATEST INSIGHTS ON WASTEWATER

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
-
Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
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.
