Core Jet Aeration & Jet Mixing Systems

Our engineered configurations replace high-maintenance mechanical surface aerators and clog-prone
fine-pore diffusers with robust, high-alpha mass transfer technologies.

Slot Injector™ Systems

Slash volumetric flow by 55% and lower blower energy up to 15%. Geometrically optimized slot chambers generate extreme venturi forces to maximize gas entrainment and interface renewal.

slot injector systems

Aftermarket Aeration Systems

Rapidly upgrade failing legacy infrastructure without major reconstruction. Pre-engineered Rapid Series™ Slot Injectors drop into existing basins to boost oxygen transfer using your facility’s active blower network.

Learn more

Jet Mixing Systems

Distribute uniform mixing energy across up to 100 discrete tank locations using a single external pump. This creates a continuous toroidal flow profile that eliminates stagnant pockets.

jet mixing systems

Back-Flush Systems

Clear matted rags and entrapped solids without entering the basin or interrupting treatment. Integrated airlift pump mechanisms reverse hydraulic flow to flush inner nozzles instantly.

Learn more

Effluent Decanters

Draw clarified supernatant cleanly without disturbing the settled sludge blanket. Features rugged Type 304L stainless steel construction, UV-stabilized floats, and a heavy-duty cast-iron swing joint assembly.

Learn more

Jet Aeration Systems

Maximize oxygen transfer rates across high-solids and surfactant-heavy waste streams. Concentric nozzles simultaneously discharge air and motive liquid along the basin floor to sustain high alpha factors.

Learn more

Total System Responsibility

Eliminate multi-party design friction and component mismatches through single-source integration. Consolidates injectors, piping, pumps, and blowers into a fully aligned, pre-engineered hydraulic package.
