Dust Suppression

The addition of moisture to the dust source to control the emission of dust.

Spraying water onto the source of the dust limits the emission of the dust. However, the combination of dust and moisture in the same area does require that all Dust Suppression systems require regular inspection and/or maintenance in order to remain functional.

In many Dust Suppression systems the spray nozzles are installed in inaccessible places and require the production equipment to be shut-down to allow for maintenance of the suppression system – as a result these systems become difficult to maintain.

Our Mist’em® Dust Suppression systems are designed to provide for easy access to the nozzles – allowing for regular inspection and maintenance to be performed on individual nozzles whilst being ‘on-line’.

There is no need to wait for a plant shut-down. Our individual nozzles can be maintained whilst the production equipment is in operation.

We offer two types of Dust Suppression Systems:

‘Wet’ Suppression systems use pressurised Water to create a mist of water particles to limit airborn dust at the source.

Suitable for applications where added water is not critical.

Conveyor discharge points, Rom tip areas etc.


‘Wet’ Dust Suppression systems produce a liquid mist to contain the dust emission.

The mist is less affected to air movement than the fine atomised mist – thus making this more suitable for applications where the dust source can not be fully enclosed.

This system uses presurised water and can only be used on product that can tolerate the addition of moisture.


  • Lower capital cost
  • Uses only water
  • Less maintenance
  • Can be used in ‘open’

‘Atomised’ Suppression systems use a combination of pressurised Water and Air to create a very fine mist with small water particles to control fine dust.

Suitable for applications where added water needs to be minimised.

Process equipment, Crushers, etc


‘Atomised’ Dust Suppression systems produce a very fine mist that is capable of trapping small particles of dust.

The atomised mist is affected by air movement and this type of system is suitable for applications where the dust source can be enclosed.

The low water consumption makes this system ideal for products that can not tolerate high levels of moisture.


  • Lower water consumption
  • More efficient dust entrapment
  • Lower water pressure

Both the Wet and Atomised Dust Suppression systems are limited to processes where the product can tolerate the addition of moisture.

Due to the combination of dust and moisture both these type of systems do need regular inspection and periodic cleaning.
