The abs submersible aerator mixer OKI is a high capacity aerator that can operate as both, an aerator and/or mixer, for municipal and industrial wastewater applications.

Sulzer abs OKI

(Suitable for discontinuous aeration processes)

Maintenance or changing the plant configuration is always easy thanks to the OKI's liftability. This makes it unique and suitable for discontinuous aeration processes, such as simultaneous denitrification, nitrification, and SBR (Sequence Batch Reactor) processes. The OKI keeps the high aeration capacity over its lifetime and is capable of operating in deep tanks with levels deeper than 12 m and in liquids with high dry matter present. The high pumping and mixing capacity of the OKI aerator makes it the right choice for MBR and MBBR processes.
