At what angle are bar screen assemblies typically installed from the horizontal in a waterway?

• A. 30- to 45-degree
• B. 45- to 60-degree
• C. 60- to 80-degree
• D. 80- to 90-degree

Answer: (C)

Bar screen assemblies are typically installed at an angle of 60 to 80 degrees from the horizontal in a waterway. This steep angle enhances the effectiveness of the screens in capturing large debris while allowing water to flow through. The steep incline helps minimize the accumulation of material on the screen surface, facilitating easier cleaning and maintenance. Additionally, the angle ensures that the water flow can wash over the screens efficiently, thus optimizing the filtration process. While shallower angles might lead to more debris buildup, steeper angles close to vertical can present challenges in structural integrity and flow characteristics, making the 60 to 80-degree range ideal for balancing these factors.
