Fine Mesh Filter Screens: Transforming Rooftop Rainwater Quality in High-Rise Projects

Fine Mesh Filter Screens: Transforming Rooftop Rainwater Quality in High-Rise Projects

Urban rooftops face constant exposure to pollution, dust, bird droppings, and extreme weather. In high-density buildings, a fine mesh filter screen—with engineered perforated support—delivers the high-performance filtration that city water systems demand.

Case Study：Shanghai Office Tower

A 40-story office building in Shanghai used ordinary mesh pads in its rooftop rainwater tanks. Pollution and fine grit from the city air caused blockages and led to muddy water in the system—raising complaints from facilities teams and threatening landscape irrigation.

Upgrade and Results:
The building management installed premium fine mesh filter screens with stainless perforated backings in every tank.

• Cleaner Water: Fine dust, urban grit, and pollen blocked at the source, keeping tanks clear for irrigation and cleaning use.

• Zero Collapse: The perforated mesh prevented filter sag, even during summer downpours.

• Longer Filter Life: Filter screens were only changed twice a year (down from monthly).

Scientific Validation

• ScienceDirect – Water Research: Fine mesh screens reduce rooftop tank contaminants by 70%+ in polluted urban environments.

• International Water Association (IWA) and ASCE: Endorse fine mesh plus perforated support for city rainwater systems.
