Insights

The Passavant® Fine Bubble aeration system with proven membrane diffuser is used in wastewater treatment plants worldwide and is constantly being further developed. Unlike rigid-porous diffusers, e.g. made of ceramics, intermittent operation is possible, thus ensuring high operational reliability and variability.

For air supply, tiny slits open in the elastic membrane so that fine air bubbles are released into the water. When the air supply is turned off, the slits close completely. At the same time, the hydrostatic head presses the membrane firmly onto the support pipe, thus sealing the air inlet opening. This double seal prevents liquid from entering the aeration system.

Diaphragms made of different elastomers are available to provide the right diffuser for any wastewater.
