Thin layer sedimentation systems

Aimed at intensifying sedimentation processes and separation of suspended and colloidal particles from water. Can be applied in sedimentation tanks of all types, clarifiers, flocculation chambers, that use gravitation as the means of impurities separation.

“SOTEL” polymer modules

“SOTEL” polymer modules is an effective way of screening and settling particulate and fine pollutants. The construction of “SOTEL” PVC polymer modules provides for creating suitable conditions for settling of suspended substances following a shorter path. Polymer modules are mounted on the supporting structures of the facilities for sedimentation. Polymer modules can be produced in cartridges.


  • may be used for any method of treated water collection;
  • sedimentation time and tank area is decreased by up to 30%;
  • lower service costs due to the decreased filter loading;
  • sedimentation processes and separation of suspended and colloidal particles from water are intensified due to larger contacting surfaces;
  • the sediment effectively slides down the surface of the shapes.
