Slot Injector Systems
Introduced in 1979 by Bayer AG, the Slot Injector is similar to a modern jet aerator but uses a slot-shaped configuration to achieve higher efficiencies.

The slot-shaped nozzle and mixing chamber provide a greater shear surface for mass transfer than a circular jet opening of identical area.

The Slot Injector™ system is a superior jet aeration system that is specifically applied to industrial biological treatment processes where fine screening is a standard pretreatment operation in both conventional and advanced air activated sludge applications.

The propulsion jet of the Slot Injector creates a zone of extreme negative pressure which enhances gas entrainment. Its mixing chamber incorporates a distinguishing pressure recovery zone that distinguishes it from a conventional jet aerator.
