Multi-Layer Mesh Screens: Unlocking Reliable Rain System Prefiltration in Real-World Projects

Multi-Layer Mesh Screens: Unlocking Reliable Rain System Prefiltration in Real-World Projects

In green buildings and high-traffic commercial sites, rain system prefilters face tough challenges. Standard filters block easily or let dirt slip through. A multi-layer mesh screen prefilter—combining perforated, medium, and fine mesh layers—solves these issues, as seen in recent city infrastructure upgrades.

Case Study: City Hall Rainwater Upgrade

The City Hall in Cape Town was losing rainwater quality due to blocked or underperforming prefilters in its rooftop collection system. Engineers replaced old single-layer filters with multi-layer mesh screens that combine graduated perforated and fine mesh sheets.

The Results:

• Progressive Particle Capture: Coarse debris stopped by top perforated filter, fine mesh below traps silt and pollen.

• Less Cleaning: Prefilter maintenance dropped from monthly to twice a year.

• Consistent Clean Water: Storage tanks remained sediment-free even during windy storm seasons.

Research-Backed Performance

• ScienceDirect – Water Research: Multi-layer prefilters remove up to 90% more particles than single mesh.

• ASCE and IWA: Recommend multi-layer mesh screens for modern rainwater and greywater systems.
