BIOdek® Cross-Fluted Fills



High efficiency – low effluent rates

The structure and the high specific surfaces from 70 to 320 m2/m3 of GEA 2H BIOdek® cross-fluted fills are perfectly adjusted to all requirements in biological sewage treatment processes. Different shapes of the fills allow growing thin or thick biofilms depending on what the process requires.
