Laboratory testing and field tests

In our laboratory we systematically test all products for mechanical strength and head loss performance in clean water. As part of regular audits we test the JetFlex® diffusers’ durability and material fatigue with up to 1 million cycles. Furthermore, we cooperate with external partners, for example, Leibniz-University Hannover, Tongji University Shanghai/VR China, German Rubber Institute (DIK), Hanover/ Germany, GSEE Inc, La Vergne /USA and many more.


In case of applications with specific waste water substances we recommend conducting pilot studies. Diffusers made of different membrane materials are installed on a testing frame. After a certain contact period with waste water the membrane characterictics possibly change thus durability and longevity may be estimated.


In addition, we offer to evaluate the residual life span of our diffusers for our customers. After dismantling single diffusers out of the aeration tank, we examine the head loss caused by potentially changing materials and deposits. In that way, we can estimate whether a chemical and/or mechanical cleaning can extend the diffusers’ life time or it is more economic to completely replace the diffuser.
