Abstract
A method and/or a system filters particles using a screen with modular segments installed into a frame. The frame has a perimeter structure and an orthogonal array of support members. The segments have a segment perimeter frame, an orthogonal array of ribs and a mesh stretched across the segment. When the mesh of the segments is damaged, the damaged segment is removed from the frame and a replacement segment is installed.
