LINEAR MECHANICAL SCREENS
Linear mechanical screens located at the entrance of wastewater treatment plants are the first line of defense of the system. They protect pumps, valves and subsequent process equipment by removing solid materials, fibers, plastics, metal particles, wood and textile waste from wastewater coming from sewer or industrial lines. Thanks to their fully automatic, continuously operating and minimum maintenance requiring structures, these equipment ensure efficient and safe operation of the plant.
WORKING PRINCIPLE
Linear mechanical screens are generally placed in the channel vertically or at a 60–75° inclination. While wastewater passes through the screen openings, large particles are retained on the surface. These materials accumulated on the screen surface are automatically transported upward by chain or belt rake systems. Solid materials are transferred to the discharge chute or press unit located at the top. The rakes clean the surface by moving up and down between the screen bars. This movement is driven by a motor-reducer system. The system automatically activates according to the level difference sensors or time-controlled operation principle. Depending on the plant's flow rate and wastewater characteristics, screen spacing is generally selected between 3 mm – 25 mm.

APPLICATION AREAS
Linear mechanical screens are essential equipment that reduce solid material load, lower maintenance costs and increase the safety of the entire system in treatment plants. They offer long-lasting solutions with their simple but effective designs, automatic operation features and durable material structures. With compact body, quiet operation and high separation efficiency, they are indispensable first-stage equipment of modern treatment plants.
Municipal wastewater treatment plants (pre-treatment lines)
Industrial wastewater lines (food, textile, chemical, metal industry)
Rainwater collection and pumping systems
Cooling water intake structures
River or surface water intake structures
