The operating mechanism of the screens, tried and proven over many years


Wastewater enters the screen at a flanged inlet and flows into a horizontal semi-circular perforated screen panel. The perforation size is chosen according to the individual separation requirements. The screen panel retains the solids, and the screened water flows by gravity into an outlet or open channel, or, if desired, into a collection sump with an outlet flange.
A set of slowly rotating brushes attached to a central shaft transports the rejected solids from the top of the perforated plate to an ejection chute where a mechanical scraper cleans the brushes. The chute design can be modified due to specific installation conditions so that the rejected solids can be either passed into a container, screw conveyor, or screening press.
Neither greatly fluctuating operating conditions nor discontinuous flows can impair the performance of our contec screens. Even dry-running shortens the service-life of the adjustable brushes only insignificantly – operating periods of up to 40.000 hours are not uncommon.
Basically, we classify our screens based on application and size. As a small, flexible company in association with strong partners, we are able to offer the optimal screening system assembled from various components for almost any application.
