Oxidation ditches often serve as a cost-effective and reliable way to treat wastewater from small- to medium-sized communities. They are designed to meet stringent water quality standards by removing organic pollutants and nutrients, using a single reactor for multiple treatment steps, including carbonaceous BOD removal, nitrification and denitrification.
For decades, these oxidation ditches have depended on brush, disc and other mechanical surface aerators. These systems often have high maintenance requirements, uneven oxygen distribution and heavy sludge buildup on the basin floor. Titus Wastewater Solutions recently announced the release of the Twister SDF Aerator — an air-driven system designed to transform the way municipalities and industrial facilities aerate not only oxidation ditches, but also headworks, polishing lagoons and other large treatment basins.
The Twister SDF Aerator offers powerful subsurface technology that improves mixing, prevents solids settling and extends equipment life. It continuously circulates water from the bottom up using a bottom intake and a 15-degree downward subsurface discharge. This creates true directional flow and consistent dissolved oxygen levels across the full depth of the basin — something traditional surface aerators cannot achieve. With no moving parts or electrical components in the water, it eliminates common operational headaches, reduces downtime, and improves worker safety.
“Wastewater operators have been asking for a more reliable, lower-maintenance alternative to surface aerators. The Twister SDF delivers exactly that,” says Lewis Titus, vice president of Titus Wastewater Solutions. “Our air-driven design improves treatment performance while lowering operating costs and extending equipment life.”
The Twister SDF Aerator delivers equal or superior oxygen transfer compared to traditional mechanical aerators while providing enhanced mixing to minimize sludge buildup and reduce handling costs. Its nonclogging, no-ragging design and corrosionproof HDPE construction ensure long-lasting performance with minimal maintenance. Installation is quick and requires no tethering, and all service can be performed from land-based access points. The system is also compatible with DO probes for automated control.
Engineered for versatility, the Twister SDF is ideal for applications needing directional flow aeration, and as a replacement for mechanical brush or disc aerators.
