Project Name: Upgrade of Central-Flow Fine Screens at a Municipal WWTP
Year: 2025
Scale: Retrofit of 4 Central-Flow Fine Screens, each with ≥2.42 m³/s capacity
Product Type: Non-Metallic Super Screen Central-Flow Fine Screens (3mm aperture, 9mm thick)
Client Pain Points:
The original 5mm metal screen units (4 total) showed signs of aging, leading to:
• Frequent clogging and failed washing systems
• Overflow in the inlet chamber, causing downstream process instability
• High maintenance demand due to manual cleaning
• Bottlenecking of the pre-treatment process
Solution:
• Replaced all four 5mm metal screen units with K.G.MATZEN 3mmsuper metal mesh panel
• Upgraded major components: screen plates, washing system, automation unit—fully compatible with existing channels
• Enhanced screen plate thickness to 9mm for structural integrity and durability
• Designed and integrated a high-performance washing system for cleaner operation
Technical Configuration & Verification:
Parameter |
Value |
Screen Type |
Patented Non-Metallic Super Screen |
Aperture / Thickness |
3mm / 9mm |
Unit Design Capacity |
≥ 2.42 m³/s |
Channel Width / Depth |
2.4m / 10.0m (effective depth 6.3m) |
Screen Width |
1.8m |
Open Area Ratio |
87.81% |
Assumed Clogging Rate |
50% |
Flow Velocity Through Screen |
0.8 m/s |
Effective Flow Area |
≈ 19.91 m² |
Final Capacity (per unit) |
≈ 5.97 m³/s (exceeds requirement) |
Conclusion:
Even under 50% clogging, each screen far exceeds the required 2.42 m³/s flow rate—ensuring robust, reliable performance.
Advantages:
• ≥90% Hydraulic Open Area via patented screen design
• Fully-molded non-metallic material: corrosion- and fouling-resistant
• Modular replacement: fast retrofit, minimal civil works
• High-performance cleaning system to prevent clogging
• Stable, energy-efficient operation, ensuring 24/7 treatment continuity
Services Provided:
• On-site diagnostics and technical assessment
• Precise flow calculations and model selection
• Structural compatibility design and installation
• Auxiliary wash system configuration
• Automation tuning and training
• Spare parts planning and O&M feedback support
Project Outcomes:
• Solved pre-treatment process disruptions caused by screen clogging
• Improved screening efficiency and stabilized downstream treatment load
• Reduced manual maintenance frequency and costs
• Lower hydraulic resistance, improved operating conditions
• Transformed the entire screening system into a high-performance, low-maintenance solution
