Aeration with jet aerators
The Landia AirJet is a jet aerator, which works by automatically aspirating the air into the ejector and subsequently mixing it with the wastewater during combined mixing and aeration. The Landia AirJet offers efficient oxygen transfer rates even in liquids with high solids contents, which makes it an extremely attractive solution for sewage and sludge applications.
Chopper pump with ejector system
The AirJet consists in all its simplicity of a chopper pump that has been fitted with an ejector system. Compared to most other aeration systems, the AirJet is extremely easy to install and operate. There is no need for compressors, bottom-mounted diffusers and advanced controls.
The Landia AirJet can be installed in both existing and new tanks. In some cases, there is no need to empty the tank before the system is installed. The AirJet is available as a submersible dry-installed and floating mounted on a pontoon.

AirJet – easy and efficient
With the Landia AirJet you get a simple and efficient aeration system. It can be your primary source of aeration in EQ basins, sludge holding tanks, or aerobic digesters. The AirJet can also be added for supplemental aeration in an activated sludge tank to handle peak organic loading, or as a replacement for worn-out rotors or surface aerators in oxidation ditches.
The AirJet is ideal for heavily polluted wastewater and, since the system does not clog with solids, the AirJet provides a constantly high oxygen transfer efficiency – unlike most other types of aeration.
The oxygen transfer levels are always maintained, even when we get a higher concentration of solids, so our wastewater is always aerated properly and never goes septic.
