Aeration with an ejector aerator

The Landia AirJet is an ejector aerator that works by automatically sucking the air into the ejector and subsequently mixing it with the wastewater during combined mixing and aeration.

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 control. 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 in a submersible version as 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 actual source of aeration, to counteract bothersome odours, and additional aeration at peak loads or as a replacement for worn-out rotor or surface aerators.
The AirJet is ideal for heavily polluted wastewater and, since the system does not stop, the aerator has a constant 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.

Daphne finds prime solution for primary problematical lift station

Suck it up, pressurize it and send it to the treatment plant. In theory, this should be a straightforward job for pumps at a lift station. However, as we all know, the curse of so-called ‘flushable’ products in our sewer systems is also proving that some so-called ‘non-clogging pumps’ are getting clogged.
