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.
1. Filter cycle: during the filter cycle, the solids are deposited on the smooth surface. The fines that slip through do not become lodged in the conical slots.
2. Backwash cycle: by reversing the flow, the cake and dirt are removed from the filter surface.
Non-clogging: the continuous slot formed by the V-shaped surface wires ensures a two-point contact between the particles and the slot, which minimizes clogging.
High precision slot sizes
Surface filtration: the V-shaped wires allow easy cleaning by mechanical scraping or back flushing.
Longer working life time
Low pressure drop
Strong construction: for most applications, the wedge wire screens are self-supporting
Engineered to high standards
Wedge wire nozzles prevent the outflow of filter media, activated carbon or sand and secure an even distribution of water at the same time.
Ion exchange unit and multimedia filters are often equipped with a distributor/collector. BT has extensive experience and expertise in designing the collector system for your needs.
A resin trap or strainers serves to retain particles in a process flow. The quantity of the particles is in general very low to so that cleaning can be done during flow intertuption.
