Working principle
The membrane bulges and slits open during aeration by the pressure of compressed air.
The membrane bulges and slits open during aeration by the pressure of compressed air.
The support plate distributes the air evenly over the entire surface of the membrane.
Air is spread into small bubbles, when released through the membrane.
When the air flow is turned off, the pressure of the water above presses the membrane disc tightly to the support
plate closing the small slits on the membrane. The non-return valve closes and makes sure that no water enters the pipeline.
