Our fish screen services include design and installation of large scale traveling water screens for rivers, lakes, aqueducts, canals and more. “Fish screens” with openings of 3/32” or fish-friendly screens (as shown), are available for design, manufacture and installation.
Fish screens protect fish and equipment. Our fish screens are built to National Marine Fisheries specifications. International Water Screens will also build “fish-friendly” screens. These are machines that will allow fish to swim through, while the “belting” removes the debris from the water.
Fish Screen Features
Our traveling screens offer multiple ways to collect debris while allowing or disallowing fish to swim through. Our traveling water screens are custom-designed for the location.
Water screens are constructed of heavy duty materials. Stainless steel 304, 316 and 317 are available. Water screen frames can also be made of aluminum or mild steel appropriately coated for your location.
All traveling water screen wear surfaces are covered with UHMW for long life. Screens are equipped with internal spray bar with high pressure water that removes the debris from the back side of the traveling water screen.
A complete traveling water screen system could include:
- Variable speed motor
- Trough or conveyor
- Submersible pump
- Control panel
- Differential level control
- Adjustable timer
- Hand/off/auto controls
- Belt openings as tight as 3/31’ and open as 3”
We offer many additional features for your fish screen needs.
Do you need a traveling water screen solution for a remote location without power? Is it cost-prohibitive to run power lines to the screen location? International Water Screens will design and build a generator-powered traveling water screen for a fraction of the cost.
Our standard traveling screen or fish screen has an internal spray bar with pressurized water that will blow off the debris that doesn’t fall off of the belting. International Water Screens will provide a pump for this pressurized water, or we can use domestic or fire water for the spray..
Some screens have hoods to protect them from the elements and hide and quiet the hardware.
The elevator has a conveyor belt that lifts debris from the water, as the water flows past. The conveyor drops the collected material for collection. A spray bar helps remove debris from the screen.
Any floating debris can be removed. Floating plant matter, storm detritus, algae, construction material, or garbage that normally collects in waterways. Removing debris prevents clogged pipelines, protects pumps, and can be designed for various types of debris.
Different sites have different debris problems, and different ways to remove the debris must be adapted to local conditions.
Algae and rapidly growing plants like Water Hyacinth can quickly clog waterways if they aren’t removed. International Water Screens can design a system to address your area’s specific problems.
