FSM - Dual Flow Screen


    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.

    Functional principle:
    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.
    The cleaning process can be assisted by a optional brush in dependence on the screenings load. The water flows through the screen elements which are covered either by a woven wire mesh made of stainless steel with up to 3 mm openings or with perforated plates from 1 up to 12 mm openings which create a barrier to the passage of suspended contaminants and removes them for disposal. With mesh maller 3 mm the horizontal space between the adjoining panels is positively ealed to prevent solids escaping hru the gap as would be the case if it was not sealed.  The screenings can be discharged into containers, screening washing press, screw conveyors, etc. The screen element and screen frame are sealed at the sides to prevent solids from circumventing the filter. The filter elements can be individually and quickly exchanged for ease of maintenance.
