DRYPRESS TECHNOLOGY

The Drypress Screw Press  provides a unique, cost effective solution for dewatering of municipal and industrial sludge. The equipment is designed to dewater the Primary Sludge and/or Secondary Sludge dewater sludge from a dry content of 0.8-6% to 15-25%. 

The sludge is fed to the machine via pump or inlet hopper into a cylindrical progressive three stage wedgewire or perforated drum.

STAGE 1
DRAINING

Stage 1 Draining.png

The flocculated sludge enters the the Drypress, the liquid fraction drains immediately

STAGE 2
THICKENING

A progressive and gentle compression of the sludge against the drum thickens the sludge.

STAGE 3
DEWATERING

Sludge is pressed against counter pressure cone, reaching high results in dryness.

DRUM SEAL

On the tip of the screw flight there is an elastometer to create a seal between drum and screw and to generate pressure.

DRUM WASHING

The Drum is washed by a Motorized washing ring moving up and down the drum.

PNEUMATIC
CONE

The cone pressure is pneumatically regulated to generate more or less pressure on the sludge

Our centrifuges were designed with ease of maintenance in mind.  It is one of our greatest strengths. 

Filtrate
