Hydro-Sludge™ Screen - Coarse Material Separator

A Superior Screen with Reverse Function Versatility

The Hydro-Sludge Screen is a horizontal in-line coarse material separator comprising an inlet screening zone and a pressing (compacting) zone. The coarse material retained on the stainless steel inner screen surface, is transported to the stainless steel pressing zone and onward to the outlet by an archimedean screw. Compacted coarse material (screenings) are discharged by the action of a regulating cone controlled by detection of increased torque on the drive motor, into a suitable container.

The optimum pressure for sludge supply to the screen is between 14.5 and 17.4 psi. While the unit will tolerate higher pressure for brief periods, continuous increased pressure is not desirabe

Applications

• Designed for either direct tanker, pumped feed or combination
• Ship-board preliminary treatment
• Primary, secondary or imported sludge screening

Advantages

• Enclosed system, reducing odor problems
• Screening, dewatering and coarse material discharge in one operation
• No washwater requirement
• Fully automatic for either continuous or intermittent screening of sludges with varying dry solids content
• Continuous coarse material separation under pressure with loss of pressure dependent on sludge thickness only
• 0.12" to 0.39" diameter screen perforations
• Stainless steel components
• Robust spheroidal C.I. housings at inlet and outlet ends
• Fully manufactured, assembled and tested in-house
