Ucego vacuum table filter

Fertilizers at the lowest OPEX: maximum extraction of phosphoric acid

with UCEGO® rotating table filter

UCEGO® table filter is a technology developed in the early 60’s, owned by Technip Energies and partnered with ANDRITZ which is the sole and exclusive supplier for the UCEGO® table filter since 2018 (including for the spare parts business).

The UCEGO® table filter is a vacuum filtration system, composed of single table divided into sections (30 or 36 cells, with 3 or 4 troughs), designed with a floating table concept (horizontality within a tolerance less than ±3 mm). In principle, the slurry is distributed on the system and cleaned with a counter-current floodwashing. At the end of the process, the discharge is ensured by a screw conveyor.

Ucego® rotating table filter in acid phosphoric plant



  • No distortion from thermal expansion thanks to floating table concept and horizontality within a tolerance less than ±3 mm (the filter table in stainless steel expands but stays horizontal)
  • Maximize filtration rate for all applications (phosphoric acid, potash slimes), thanks to design of 30 or 36 cells with 3 or 4 troughs -  each cell with a pronounced 10° slope with a maximum 0.85m for the liquids to be collected 
  • Higher production rate thanks to its ability to rotate very fast




  • Phosphoric acid
  • Potash slimes
