MicronFog™ Misting and Fogging System – Control Dust and Odour

Dust Suppression

With dust, especially silica dust gaining more focus from regulatory bodies, pressure is on process operators to keep dust down. Clearly the best solution is to avoid creating it or try to trap it at source.

Nevertheless, some processes do generate dust that cannot be trapped. It becomes airborne and must be suppressed. A dusty workplace damages machinery and can harm the workforce. COPD and Silicosis are linked to dusty working environments. High dust levels are unlawful under the Health and Safety Act and Environmental Protection Act. Regulators can serve Improvement Notices and in some cases, a Prohibition Notice.

MicronFog^TM can supress dust whether indoors, or outdoors. In warehouses, loading areas and factories or at site perimeters and boundaries.

Suppressing dust in the factory with fog

Suppress dust in the process area.

In a MicronFog^TM system, pressurised water is forced through laser drilled ruby nozzles. This creates a fine mist. The fog quickly mixes with the air. Dust particles and water droplets combine and fall out of the air. One can visibly notice that a dusty building clears in a matter of minutes when MicronFog^TM starts. Nozzles can be fitted in the roof to suppress dust within the building or close to transfer points and load-out points where dust is often generated.

Purchase and running costs are much lower than alternative techniques, such as dust extraction and dust collection. Power consumption is far less too when compared to other approaches.

Will the fog wet the product or my process area?

One might assume that misting would make an area wet or damp. In many dust generating processes there is a great need for the process area to remain dry.

Renby ensure appropriate water pressure control and selection of nozzles to ensure fog is fine enough to prevent the area becoming damp while effectively supressing dust.

Renby are industry leaders in dust suppression. We have a very broad range of long term experience in chemical and minerals industries. MicronFog is used in vegetable and dry powder packing where products being processed must not become wet.

Supressing Silica Dust

Silica dust is a particular area of focus for regulatory bodies due to the carcinogenic effects of respirable crystalline silica dust. There is widening pressure to reduce the workplace exposure limit for respirable crystalline silica dust levels to 0.05mg/m3.

Fog is an essential tool to suppress dust to these levels. The image shows dried silica sand being loaded into railway wagons. You can clearly see the fog spraying across the wagon as the sand is loaded. Please take a look at the video below to gain more insight. MicronFog systems can effectively remove breathable and fugitive dust in the range 0.1 to 1000microns.

Importantly, in the increasingly complex legal environment, our systems meet or exceed the EPA PM 10 standards for dust suppression.
