Nortex, a high-performance fabric manufactured by Norair Engineering Corp., plays a critical role in various environmental and water treatment applications. This specialized material is particularly known for its use in side and boot seals for traveling water screens, crucial components that ensure efficient and reliable operation of these essential systems.
Traveling Water Screens: Guardians of Clean Water
Traveling water screens are essential in water treatment plants, power plants, and other facilities that utilize large volumes of water. These screens act as a first line of defense against debris, preventing it from entering critical equipment and impacting the overall efficiency of the system.
The screens function by moving a continuous, perforated belt through the water intake, capturing debris that is larger than the mesh size. As the belt rotates, it transports the collected debris out of the water, ensuring a continuous flow of clean water.
Side and Boot Seals: The Unsung Heroes of Efficiency
The effectiveness of traveling water screens relies heavily on the integrity of their seals. Side seals are located on the sides of the screen, preventing water from leaking out and debris from entering the system. Boot seals are located at the bottom of the screen, creating a tight seal that prevents water from leaking into the screen's support structure.
