Aeration systems

Membrane Aerators:

Membrane aerators introduce air into the reactor via modules positioned on the floor of the tank. This ensures an even, comprehensive distribution of air. The membranes produce small bubbles—measuring only a few millimeters—which optimize oxygen transfer into the wastewater. Furthermore, the air supply can be controlled through adjustable blower settings. Membrane aerators are not only scalable but also rank among the most high-performance aeration systems available.

Such systems can also consist of modules equipped with a lifting mechanism. These liftable aeration systems allow for maintenance to be performed while the plant remains in operation, thereby minimizing system downtime.

Submersible Aerators:

This technology involves placing a motor on the floor of the tank to be aerated. The motor draws air from the surface through a pipe and distributes it across the bottom of the tank. Due to their low initial cost and reliable, low-maintenance operation, submersible aerators are particularly well-suited for use in equalization tanks or for sludge aeration to prevent the development of unpleasant odors.

Surface Aerators:

Surface aerators work by continuously agitating and dispersing the wastewater at the surface. This process creates a large contact area between the wastewater and the ambient air. This method of aeration is one of the oldest and most well-proven techniques.
