Mechanical bar screens are the first line of defense in wastewater treatment, protecting pumps and downstream equipment from large debris and粗杂物.

Why Bar Screens Matter

Bar screens remove coarse solids that would damage pumps, clog pipes, and interfere with biological treatment processes. Proper screening reduces maintenance costs and improves overall plant performance.

Types of Mechanical Bar Screens

Manually Cleaned Bar Screens

Used in small plants or as backup for mechanical screens. Regular manual cleaning required.

Mechanical Bar Rakes

Automated cleaning with raking mechanisms. Suitable for medium to large flows. Various bar spacings available (6mm-50mm).

Fine Screens

Perforated plate or wedge wire screens for fine screening (1-6mm). Protects membrane systems and advanced treatment.

Design Considerations

• Channel velocity: 0.6-1.0 m/s (self-cleaning)
• Head loss through screen
• Bar spacing based on downstream equipment
• Flow velocity at peak conditions
• Debris handling and disposal
