ADEQUATEC is an innovative French SMI in the water treatment market that offers a new technology for thickening and dewatering sludge with very low energy consumption and low carbon footprint, which allows :

easy, automatic and reliable operation,
low operating costs.

As such, ADEQUATEC received in 2010 the prize for innovation in eco-technologies awarded by the Ministry of Ecology and ADEME (French Environment and Energy Management Agency).

The ADEQUAPRESS technology offers exceptional advantages compared to technologies already on the market (centrifuge, belt filter…), in particular very low electricity consumption (20 to 50 times less) and very low operating and maintenance costs (3 to 6 times less).

The originality of the ADEQUAPRESS lies in the ingenious design of its self-cleaning and uncloggable drum. Indeed, unlike drums with perforated screens that clog easily, the ADEQUAPRESS drum is composed of a succession of fixed and mobile rings that slide relative to each other ensuring continuous self-cleaning (without washing water consumption) and an excellent capture rate.

With less than 10 kWh of installed power per ton of dehydrated dry matter, the ADEQUAPRESS enables its customers not only to save money and reduce their carbon impact, but also to use renewable energies (PV, wind power…) for its power supply.
