Customer value with high efficiency diffusers and IFAS textile fixed bed

Since late 1970´s Jäger’s rubber membrane diffusers are established as one of the leading brands in the industry.

This membrane expertise is now complemented by 20 years of textile fixed bed technology of CWM.

The combination of aeration with textile fixed media multiplies the benefits for customers.




JetFlex fine bubble diffusers:

High oxygen transfer rates

Nitrogen removal by intermittent operation

Long membrane lifetime

Large adjustment ratio

Low energy costs

IFAS CleartecBiotextile:

Significant expansion (up to 100%) with little or no additional aerobic volume

Increased Biological Nutrient Removal (BNR)

Improved solids settling

Greater resistance to hydraulic solids washout

Increased resilience to shock loading

Reduced solids flow to clarifiers, increasing clarifier capacity
