TUBEdek® Lamella Clarifiers (Tube Settlers)
Cost savings by smaller tanks
GEA 2H TUBEdek® Lamella Clarifiers, also called tube settlers, are used for solids removal (sedimentation processes) in water and sewage treatment. GEA 2H TUBEdek® can be used in rectangular and in circular tanks.
Sludge, sand and silts in surface water, chemical precipitation and flocculation form solids which have to be removed. The most economic process to remove this pollution is parallel plate sedimentation.
GEA 2H TUBEdek® lamella clarifiers base on this physical principle. They consist of single profiles, which are assembled to a module forming several adjacent tubes and multiple sedimentation planes. This design increases the sedimentation area by a factor of 6 to 15 per square meter footprint. Using GEA 2H TUBEdek® tube settlers therefore decreases costs by being able to build smaller tanks.
Flexibility for all different applications
GEA’s different tube settler types enable optimized sewage treatment processes. By choosing different tube lengths and heights and by varying the inclination angle, GEA 2H TUBEdek® settlers can be adjusted to all kinds of process requirements and tank geometry.
