Energy efficiency and capacity increase for aerobic treatment processes


Jäger is the pioneer of EPDM fine bubble membrane diffusers. Arnold Jäger with his company Gummi-Jäger created the world’s first JetFlex® rubber membrane diffuser in 1975 to replace the energy intensive ceramic diffusers. Since then Jäger is instrumental in the design, rubber chemistry, perforation patterns for high SOTE of the majority of today’s well know fine bubble diffuser suppliers.

Today, the diffuser activities of former Gummi-Jäger are focused  in the Jäger Umwelt-Technik  being the industry’s only one full line supplier offering  the complete range of JetFlex® fine bubble HD disc-, TD tube- and  SD strip diffusers.

JetFlex® diffusers excel by longevity and energy efficiency.

Our production facilities in Germany, China and USA support our customers on a global scale.

With retrospective effect  January 1st 2012 Arnold Jäger Holding GmbH has acquired all assets of  Cleartec Water Management GmbH. Cleartec provides  a unique IFAS process (Integrated Fixed Film Activated Sludge). This process provides performance / capacity Increase up to 100% without constructional measurement and low energy consumption due to the combination of  suspended with additional sessile biomass.

So 40 years of  Jäger´s  membrane expertise is perfectly complemented by 15 years of Cleartec´s  textile fixed bed technology.

The combination of aeration technology  with textile fixed media will benefit all Cleartec  and Jäger customers.
