A continuous sludge dewatering system using an interlocking screw mechanism to efficiently reduce moisture from high-volume feed — delivering stable outlet solids with low energy consumption and minimal operator attention.
Sludge is dosed with polymer flocculant via the integrated dosing system before entering the press, promoting floc formation for effective water release.
Multiple screws rotate at low speed, gradually building pressure along the chamber length to extract moisture without high mechanical stress on components.
Separated water drains through the screen and is returned to the treatment system, while the dewatered cake progresses toward the discharge outlet.
Dewatered sludge exits at the outlet end at 20–22% dry solids and transfers directly to downstream handling, bagging, or drying systems.
Intermeshing screw rings continuously clean the filtration screen during operation, preventing clogging and maintaining consistent throughput without manual cleaning intervals.
Handles sludge with 0.2–5% inlet dry solids — suitable for both thickened and dilute sludge streams without pre-thickening.
Continuous screen cleaning eliminates the shutdowns and manual intervention common in belt press and centrifuge systems.
Slow screw rotation speed means significantly lower energy draw compared to centrifuges at equivalent throughput.
Self-contained polymer dosing unit is factory-mounted and pre-commissioned, reducing site installation complexity.
Few moving parts, no high-speed rotating components, and no filter cloth replacements result in low lifetime maintenance cost.
Designed for uninterrupted duty in industrial and municipal treatment plants with consistent sludge loads
The Multi Screw Press is a compact, automated system designed for continuous sludge dewatering across municipal and industrial applications.
It delivers consistent output with minimal operator involvement and significantly lower operating costs compared to traditional systems.
