Why HydroWet offers by far the best Dust Suppression solution in materials handling applications

There are many methods of dust suppression available in Australia, however the best dust suppression solutions are those that incorporate HydroWet, a concentrated surfactant specially formulated by Dust-A-Side to improve the wetting ability of water, particularly on hydrophobic materials such as coal and other fine ores.

The main reason for its proven success is the fact that as a superior wetting agent, HydroWet helps to lower the surface tension of water particles, leading to smaller water droplets (between 5 and 10 microns) that attract dust particles to them, via agglomeration.

As you can see from the following diagram, larger water droplets displace more air, allowing the fast-moving airborne dust particles to simply flow around them.

The best dust suppression solutions use Hydrowet

However with more than 200 highly advanced dust suppression systems in operation globally, Dust-A-Side understand that the secret of effective dust suppression is to match the size of atomised water droplets with the dust particles.

We know that when they are of equivalent size, there’s no getting around it; they collide, combine and fall to the ground assisted by gravity.

Other benefits of this proven dust suppression solution

As well as capturing and subduing the respirable dust (less than 10 microns) that can cause everything from irritating eye and throat issues and vision impairment to severe health risks, adding HydroWet to a dust suppression system also helps to:

  • Minimise water usage, so you’ll save on water costs — PLUS your water resources can be put to better use elsewhere
  • Prevent excessive water pooling (a significant safety risk), and
  • Reduce the likelihood of blockages in the downstream materials handling process caused by adding excessive amounts of water/moisture to the material.

For effective dust suppression and wetting, the recommended surface tension of the solution is below 45mN/m — which is much lower than the standard surface tension of water, which is 71 – 73mN/m.

As a fast and effective wetting agent, HydroWet is very cost-effective compared to using water only, since only a small amount of HydroWet is needed to have the desired effect.
Typically, HydroWet is used at a dosage ratio of 500 ppm.

This makes it the perfect dust suppression solution for a host of applications, including:

  • conveyors,
  • stockpiles,
  • transfer points,
  • tipping areas,
  • surge bins,
  • loading terminals,
  • storage facilities,
  • demolition sites,
  • excavations,
  • quarries,
  • rock crushing plants
  • and more.
