A solid-liquid separating filter medium for sewage, waste water, etc. comprising a filter screen in which a number of filaments are closely aligned in parallel in the same direction and crosswise bonded to cross-members at predetermined points thereof to form integral blind-like structure, the filaments having a maximum diameter of 0.5 mm and the cross-members being spaced from adjacent cross-members by at least 3 cm.
A solid-liquid separating filter medium for sewage, waste water, etc. comprising an inner cage formed by bonding a plurality of lateral frame crosspieces arranged at certain spaces and vertical supports arranged at plural points on the circumference of the lateral frame crosspieces to cross at right angles on a surface thereof at intersecting points of the lateral frame crosspieces and the vertical supports, and an outer wall on an outer surface of the cage, the outer wall formed by a single filament wound closely upon itself in the circumferential direction, but at a certain spacing, on the outer surface of the cage.
