Sludge dewatering process

DehydrisTwist is an innovative mechanical dewatering process for sludge from drinking water and sludge from wastewater.

It is a tailored solution for:

• the energy efficiency challenges and
• greenhouse gas emission reduction.

It allows to achieve a 30% reduction in sludge mass compared to conventional dewatering.

The quality of the dewatered sludge is well adapted to sludge recycling and volume reduction for transportation.

Because it produces auto-thermal sludge, Dehydris Twist exempts from an energy-intensive thermal-drying stage before incineration.
