Insights

With the Passavant® Fine Bubble Aeration Aqseptence Group offers you high quality diffuser which are employed in wastewater treatment plants throughout the world and have been continuously improved and developed by our company for more than 25 years.

When air is supplied, fine slits are opened in the elastic membrane and fine air bubbles are released into the water. When the air supply is cut off, the slots close completely. The hydrostatic head presses the membrane firmly onto the support pipe, thereby the air inlet opening is sealed. This double sealing procedure prevents any liquid entry into system. In contrast to rigid porous diffusers e.g. ceramic, intermittent operation is possible and a high level of operational reliability and flexibility is this ensured.

In order to supply the appropriate diffuser for every treatment process, AS provides a variety of elastomer membranes which are created for the individual type of wastewater.
