GLOSSARY
Dust Suppression
Dust suppression uses fine water mist to agglomerate airborne particulates so they fall to the ground. In Indonesian construction, mining, and industrial yards, high-pressure misting suppresses PM10 and PM2.5 dust at the source.
Also known as: Dust control · Particulate suppression · Air quality misting
How mist suppresses dust
Airborne dust particles (PM10, PM2.5) remain suspended because they’re too small to settle under gravity. When water droplets of similar size contact dust particles, they agglomerate into heavier droplets that fall to the ground. This is the physical mechanism behind all water-based dust control.
Droplet size matters for efficacy
Conventional water spray (large droplets) rains out before particles have time to interact with droplet surfaces. High-pressure misting produces droplets of similar scale to target particulates (10 microns), maximising collision probability. A mist curtain at a construction boundary can reduce airborne PM10 by 60–80%.
Indonesian applications
- Construction sites (Jakarta, Surabaya, Medan): Perimeter dust suppression for tall-building demolition, excavation, concrete breaking.
- Mining operations (Kalimantan coal, Sumatra nickel): Haul-road suppression, crusher stations, stockpile control.
- Industrial yards: Cement manufacturing, quarry operations, woodworking.
System specification
Dust suppression requires different engineering than cooling: larger nozzle spacing, wind-rated positioning, higher flow per zone, and typically ruggedised outdoor installations. MistSystem provides industrial-grade platforms for Indonesian dust suppression on case-by-case basis.
