Sludge dewatering: Adequatec confirms its commitments for 2026
Energy efficiency, reduced reagent use, water management, and total cost of ownership are now key criteria for sludge treatment projects in municipalities and industrial facilities.
At Adequatec, our screw press sludge dewatering solutions combine on-site reliability, proven efficiency, and demonstrable performance in real-world operation.
The selection of the Hi’CAP Screw Press project as one of the 26 winners of the Innov’Eau – France 2030 award confirms the relevance of these technological choices.

ADEQUATEC, a French company founded in 2001, filed its first patent in 2005 and designed, industrialized and marketed the first screw presses on the French market in 2006.
Thanks to its commercial successes, in France but also internationally, ADEQUATEC has not stopped developing its products by making them even more sober, more robust and communicating. The second generation was released in 2017.
Our company
Context of our offer
With 1,500,000 MS/year of sewage sludge produced in France and the associated economic/ecological/societal constraints (odors, substance concentrations, transportation, emissions), the market has been very dynamic for the last 20 years.
While perforated screen screw presses first appeared on the French market in the 1980s, they were discontinued 10 years later due to proven constraints: low capture rate, high water and polymer consumption, frequent clogging and frequent screen breakage.
