Area of use

The Gravity Belt Thickener can be used as:

  • Final step to increase the sludge DS concentration to 6-8%. Therefore, replacing conventional gravity static thickener flotation system.
  • Pre-dewatering stage when combined in-line with a Belt Filer Press to optimize the Belt Filter Press operation and performance.
  • Sludge volume reduction before anaerobic digestion process to reduce digester size.


The EMO Gravity Belt Thickener range has been especially designed for very high capacity installation. Its mechanical functions and components have been adapted to process conditions up to 200m3/h of raw sludge per GBT.
