PERFORATED SCREEN

Perforated screens are installed in the inlet channel of wastewater treatment plants to remove coarse solids before they enter the system. By reducing the incoming solid load, they protect downstream equipment from damage, clogging, and excessive wear. The screening surface features a moving belt design composed of sequentially assembled perforated plates with 5 mm diameter holes. These plates are interconnected by a chain mechanism and operate continuously along the screen path.

Captured solids are automatically conveyed to the discharge chute, ensuring uninterrupted and efficient operation. A specially designed rake system prevents screenings from falling back into the channel, while dual surface brushes and integrated washing nozzles provide effective and continuous cleaning of the screen surface. The system operates via an automation-controlled panel that responds to the water level in the channel, ensuring reliable and energy-efficient performance.
