Fermenter with concrete dome roof - Gönen - Turkey

Project Gönen, Turkey – our first fermenter with concrete dome roof!

At our biogas plant Project in Gönen (Turkey) we are currently building our first fermenter with a concrete dome roof.

This roof form is manufactured with special formwork systems.

Due to the well-thought-out static dissipation of the support forces, there is no center column, since everything is supported by the outer walls.

This has several advantages over a system with center support such as:
– more volume available for the residence time
– substrate can be better homogenized
– concrete -, formwork – and coating works of the center column are not necessary anymore.
