Which type of screen has radial vanes that facilitate movement?

Wing screens are specifically designed with radial vanes that aid in the movement of water and debris through the screen. The radial vane design allows for better flow dynamics, improving the efficiency of screening and allowing materials to be moved away from the screen surface more effectively. This feature is particularly beneficial in managing larger volumes of water with varying levels of debris, as the design helps to mitigate clogs and enhance the overall screening process.

While coarse screens, fine screens, and bar screens serve important functions in water treatment and solid separation, they do not incorporate the vane design that characterizes wing screens, which sets them apart in terms of facilitating movement and enhancing flow.
