The screw screen TTC/C is a machine designed for installation in channels, transporting, compacting and discharging the solids present in urban and industrial wastewater. Brushes fit on the screw allows self-cleaning on the compaction area. Through screw rotation, solids are transported to the compaction and discharging section. The spiral screw slides on replaceable wear bars to prevent the spiral-pipe friction. The compacting zone is composed of a circular mesh sieve.
