WASTEWATER
How To Choose Among Wastewater Screen Options
Wastewater screening isn’t one-size-fits-all. The right choice depends on flow, debris, and efficiency needs, with long-term performance and maintenance costs shaping the best solution.

Cloth Media Offers Chemical-Free Alternative For Advanced Primary Treatment
Pile cloth media filtration technology has been around for decades, used mainly for tertiary wastewater treatment — a final stage of the treatment process — to filter effluent before it leaves the plant. However, the technology is now poised to provide extensive benefits as an advanced primary treatment technology. It stacks up well against other methods, which include chemically enhanced solutions that present additional operating costs and ultrafine screens that remove fewer solids.

Achieving Reliable Ammonia Removal In Lagoon-Based Treatment Systems
For most small to midsize lagoon-based wastewater operations, maintaining effluent quality throughout the year is a challenge. Much of this is fueled by the difficulty of meeting permit limits for ammonia discharge, especially during winter months when the temperatures are colder. As a result, lagoon managers would benefit significantly from more reliability in the ammonia removal process.

Membrane Aerated Biofilm Reactor Technology Validated For Title 22 Compliance
Title 22 of California’s Water Recycling Criteria is among the strictest water treatment standards for water recycling and reuse in the United States. Fluence’s MABR demonstration plant was installed at the Codiga Resource Recovery Center (CR2C) in Stanford, California, in January 2018 for the purpose of third-party evaluation. The testing parameters included criteria to evaluate reliable enhanced nutrient removal in the form of Total Nitrogen, which is increasingly important across the United States and difficult and costly to achieve through conventional wastewater treatment.

Eliminating Sludge Islands In Your Wastewater Lagoon
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons.

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.
