Biosolids Sludge Dewatering Solutions
Boosted wastewater sludge dewatering with a piston press
The Dehydris* Twist unit is based on the Bucher Unipektin piston press, which is fed with drinking water sludge or pre-thickened wastewater sludge conditioned with reagents (polymers possibly mixed with mineral reagents).
The press, equipped with semi-solid drainage elements, operates in cycles (from 2 to 3 hours). The length of the cycle depends on the type of sludge and efficiency required (dryness or flow rate). Each cycle is made up of three, entirely automated, main phases:
