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
