Rotary Screw Screen Compactor


The rotary screw screen is used for the separation and subsequent dewatering and compacting of the solid content in wastewater coming from industrial and municipal plants.

The machine is composed by:
• External structure in stainless steel AISI304 L/316 L
• Screw in high carbon steel or stainless steel AISI304 L/316 L
• Outer rotary drum concentric to the loading basket (perforated holes profile or wedge wire)
• Internal loading basket
• Transport section: tubular
• Discharging section: with or without compactor
• Single drive unit
• Supporting adjustable foot
• Available also as in-tank version (up to size 1600)
The solid in the sewage enters in the basket clogging it, creating an increase of the level before the filter.
A level sensor sends a signal to start the rotation of the screw screen and consequently of the outer rotary loading drum. During rotation the outer rotary loading drum discharges solid in the screw conveyor with the aid of outer rotary loading drum washing system.
The outer surface of the screw screen is further cleaned by brushes fixed on the outer side screw so that makes cleaning action during rotation.
The compactor (optional) located at the end of the transport section, on top of the machine, makes compaction and dehydration of solid, to reduce weight and volume.

• Low speed of rotation and no intermediate supports
• Self-cleaning with brushes fit on the screw
• Low maintenance and low initial investment
• Considerable reduction of volume and weight at the end of processing (up to 50%) using the optional compactor
• High percentage of solid removed
