Wastewater treatment screw press SEPCOM

for sludge dewatering

Presentation
SEPCOM Pulp and Paper Horizontal is a horizontal screw press separator engineered for solids‑liquid separation in pulp, paper and related industrial streams. Key construction elements include a compensator hopper, self‑adjusting counter‑pressure diaphragm and a cylindrical self‑cleaning screen; modular screw options allow adaptation to different materials and wear conditions.

Function
The unit operates by combined gravity drainage and mechanical compression. A feed section with compensator tank and overflow hopper supplies the stainless steel casing that houses a screw conveyor and cylindrical screen basket. Liquids pass through the screen while solids are conveyed and compacted toward the diaphragm outlet where a material plug forms, enabling automatic discharge and preventing liquid carry‑over. Drive is provided by an electric motor and gear reducer with splined output shaft directly coupled to the screw.

Features

• Modular screw available in wear‑resistant SINT engineering polymer (easy handling and cost‑effective spare parts)
• High‑performance, self‑cleaning cylindrical screen basket
• Designed for continuous duty
• Maximum hydraulic capacity: 65 m3/h
• Maximum dry solids in separated solid: 32%
• Typical dry solids in separated liquid: < 5%

Benefits

• Consistent separation performance with reduced clogging risk
• Lower overall management costs for digestate and similar streams
• Reduced assembly and maintenance time due to modular components
• Affordable, readily available spare parts

Options

• Various diaphragm outlet types
• Different SINT polymer screw configurations and stainless steel screw option
• Multiple screen basket sizes and slot widths
