How To Rebuild Traveling Water Screens

Rebuilding traveling water screens is not a simple task, but thankfully theres a company whos got your back. SSI rebuilds all designs, makes and models of traveling water screens. Their rebuilding program refurbishes traveling water screens back to their original specifications using only exact replacement parts.

Once your water screen is at their facility, it is completely disassembled and sandblasted to bare metal. The complete traveling water screen is then inspected by our engineers
and a detailed inspection report is prepared outlining its exact condition and what repairs are necessary. Should the traveling water screen require repairs beyond the scope of the original cost estimate, a new estimate is prepared and emailed, along with digital photos to the customer for evaluation.

During the rebuild process each traveling water screen receives new replacement parts or repair to existing parts and frame assemblies. Also during the rebuilding process we can offer upgrades for the traveling water screen to overcome any type of problems it previously had and to ensure the rebuilt screen will provide years of dependable parts and service. Once the main frame and sub assemblies have been rebuilt, the entire traveling water screen and all of its parts are coated with an immersion-service-rated epoxy paint. The traveling water screen is then reassembled and test run is completed.
You also have the option to build new water screens:
Whatever your facility’s screening need– debris removal, fish handling, or heavy duty, continuous running conditions– SSI can design and build a screen to meet your demands.

Their team of engineers evaluates flow velocities, well depths, corrosion factors, debris loading and other vital performance conditions in order to ensure maximum durability and maintenance-free operation of your new water intake screen.

Traveling Water Screens have been screening raw water intakes since it became necessary to have clean, debris free water. Simplistic in design the basic Traveling Water Screen has not changed much in over 100 years. Except for some minor design variations, there are two basic screens in use worldwide today: Thru Flow Water Intake Screen and Dual Flow Water Intake Screen.

Mechanical Bar Screens
The SSI Mechanical Bar Screen is a Thru-flow rear discharge design that consists of a continuous series of rakes, toothed for engaging the bar rack. The ends of the rakes shall be mounted on the endless strands of roller chain operating overhead and foot sprockets. As raw water passes through the bar rack, large floating and suspended debris will be impinged on the upstream rack surface. When the screen is operated, the rake teeth will engage in the bar rack, lifting trapped debris. As the rakes continue ascending over the head sprockets, the rakes will discharge all debris into a refuge trough.

The screens can be manufactured in either carbon or 316 stainless steel. Inclined angles up to thirty-five degrees can be achieved due to the rigid self contained box structure. Our design will fit intakes 2 feet to 14 feet in width and up to 106 feet in length.

Let SSI intake expertise help you choose the right configuration and debris removal capacity for your unique intake requirements.
