Advancing Wastewater Aeration Technology: Airlift Innovation for Oxidation Ditches
Oxidation ditches, or “racetracks,” have been a trusted upgrade from lagoon systems for decades. Their closed-loop design supports long solids retention times (SRT) and dependable biological treatment. Yet one challenge has persisted: how to aerate and circulate water effectively within the ditch. Traditional mechanical aerators such as brushes, discs, and low-speed surface units have long […]
The Hidden Costs of Brush, Disc, and Low Speed Surface Aerators in Oxidation Ditches and the Better Alternative
Oxidation ditches, or “racetracks” as many operators call them, have been a workhorse in wastewater treatment for decades. They provide a controlled environment for aerobic digestion, keeping solids suspended and oxygen levels high enough for bacteria to do their work. But while the process is dependable, oxidation ditch aeration has often been the weak link. […]
Smarter Sludge Management – Part 3: How Floating Aeration Enhances Odor Control, Compliance, and Cost-Efficient Lagoon Performance
In Parts 1 and 2 of this series, we explored the challenge of sludge buildup in municipal and industrial lagoons—and how floating aeration, particularly the Titus FL Floating Aerator, provides a powerful and cost-effective alternative to dredging. By delivering deep, continuous mixing and robust oxygen transfer, these systems redefine what’s possible in lagoon sludge management. […]
Sludge Reduction Without the Freeze – Part 2: How Floating Aeration Cuts Costs and Delivers Year-Round Performance
In Part 1 of this series, we explored the hidden costs of sludge buildup in municipal and industrial lagoons and why traditional aeration systems often fall short in truly addressing the problem. Now in Part 2, we’ll look more closely at how harsh seasonal conditions, rising BOD loads, and ever-tightening budgets create even greater barriers […]
Rethinking Sludge Remediation – Part 1: How the Right Aeration Technology Transforms Municipal and Industrial Lagoons
Sludge buildup in municipal and industrial wastewater lagoons is a growing and costly challenge. Across North America, operators are facing rising maintenance costs, shrinking lagoon capacity, non-compliance risks, and frequent dredging bills that can run into hundreds of thousands—even millions—of dollars. And yet, most lagoon systems are still relying on outdated or misapplied aeration technologies […]
