The FSM Dual Flow Screen was developed to deal with particular problems associated with waste water pre-treatment and raw water intake.
FSM is working in this field since 1973. The first machines are used to generate cooling water for power plants and pulp and paper mills from rivers.
Parallel to the increasing demands of users, FSM introduced modifications to the basic design. These have resulted in an optimum product for the preliminary treatment of waste or river (sea) water - providing high performance coupled with low operating costs. The Dual flow screen is a very fine screen with a high screenings capture rate and excellent protection for membrane systems.
The unscreened waste water flows from both sides through the filter elements.
The outlet is make by an opening in the frame which is located in the middle of the screen frame. The filter elements form a continuous filter belt which is cleaned by a spray bar at the upper deflection point.
