Wedge wire screen is a welded stainless steel construction mainly used for filtration, separation and retention of media. It is made of surface profiles, usually V-shaped, that are resistance welded onto support profiles.

The distance between the surface profiles is controlled very accurately and forms the slot opening through which the filtrate flows.

①Filter cycle: during the filter cycle, the solids are deposited on the smooth surface. This ‘cake’ acts as an extra filter for finer particles. The fines that slip through do not become lodged in the conical slots.

②Backwash cycle: by reversing the flow, the cake and dirt are removed from the filter surface
