Fish Protection Screens

Fish protection screens system design utilizes low velocity flow(typically < 1/2 fps) through the wedge wire screen surface which minimizes impingement and danger to aquatic life.

Profile wire fish screens prevent entrainment, injury, or death of the targeted aquatic species by physically  precluding fish from entering a water intake.

Wedge wire tubes are made during simultaneous winding of specially profiled working wires on a spiral and welding them to carrying wires placed along the tube. This technology allows the production of wedge wire screens when very high gap precision and screen resistance are required. Due to using the newest welding technology we can obtain various distances between carrying wires, very accurate and repeatable gap and therefore produce screens according to customer’s particular requirements.

Applications of Stainless steel 304 fish diversion screen

Wedge wire screen is the widely using screen for filtration and separation in liquid/gas, mining, food, water wasting, and so on.

Advantages of Stainless steel 304 fish diversion screen

1. Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.
2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.
3. Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media.
4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP)
5. Long live: Welded at each intersection creating a strong and durable screen.
6. Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.
7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.
