Dust suppression systems

Airborne dust is a worker health issue, a neighbour relations issue and a regulatory one. We weigh it down with atomised water and bring it to the ground.

Atomising / misting

How dust suppression works

Fine dust particles suspended in air take a very long time to settle under their own weight. When a water droplet strikes one, the two combine, become heavier and fall quickly. That is the entire logic of a dust suppression system.

The difference from a misting system installed for cooling is droplet size. In cooling you want the droplet to evaporate in the air; in dust suppression it has to stay large enough to catch a particle and carry it down. That is why nozzle selection here is different from comfort installations.

Where we install it

  • Crushing and screening plants: the points where material is crushed and screened are the heaviest dust sources on a site.
  • Material transfer and discharge points: conveyor discharges, silo filling points, truck unloading areas.
  • Open stockyards: curtain lines installed around stockpiles that blow in the wind.
  • Unpaved internal roads: lines triggered by a motion sensor as vehicles pass.
  • Excavation and construction sites: portable solutions for temporary installations.
  • Wood processing and furniture workshops: bringing fine airborne wood dust down.

The system we build

The system consists of a high pressure pump, filtration, high pressure tubing and nozzles selected for the conditions on site. The line is positioned to form a curtain across the direction the dust travels, taking the prevailing wind into account.

Triggering works in one of two ways: a motion sensor at passing points, or programmed operation through the control panel at fixed sources. Both prevent water being used when nothing is happening.

Quotation and installation

The cost of a dust suppression system is set by the size of the site, the length of the line and the method of triggering. Nozzle prices vary with the equipment chosen, which is why we do not quote a figure without seeing the site.

Frequently asked questions

Does dust suppression actually work?
Yes. Fine dust suspended in air settles very slowly under its own weight. When an atomised water droplet combines with a particle, the two become heavier and fall quickly. On open sites, at transfer points and on internal roads the difference is visible.
Is it suitable for stack and point-source emissions?
No. Flue gas and point-source emissions need filters and cyclones. Where dust suppression works is dust dispersing in the open: excavation sites, crushing and screening plants, material transfer points, open stockyards and internal site roads.
Does the system run continuously?
It should not, and in a well-built installation it does not. At transfer points and on roads it is triggered by a motion sensor, so it runs while a vehicle or material is passing and stops afterwards. At fixed sources it runs on a programme from the control panel. Either way, water consumption falls several times over compared with continuous operation.
Why is a different nozzle used than for cooling?
Because the goals are opposite. In cooling you want the droplet to evaporate in the air before it lands. In dust suppression you want it to survive long enough to strike a dust particle and carry it to the ground. A very fine fog evaporates before it can catch anything, so dust work uses a coarser droplet and a higher flow rate.
