Depending on the industry, dust control or dust suppression can have different meanings and different requirements. Understand the options in suppression methods will allow you to choose the ideal environmental control systems given the specifics of the dust, the environment, and the cost factors.
To help to understand what needs to be considered when selecting dust suppression systems, it will be important to think about several different factors. By knowing the details of what is needed and the potential challenges, the fogging or misting system can be selected that matches the specific needs.
Type of Dust
There are many different types of dust that can be an issue in any type of industry. For example, in textile processing, very fine dust and particulate matter can cause a very real concern if electric motors and other equipment are also in use.
Other forms of dust include chemical dust or dust that contains minerals or even organic matter as dust. A good example of the latter can be found in wood processing or paper manufacturing areas.
The size of the dust particles will be important. Fogging or misting dust suppression systems are able to trap very small particulate matter, which is why this is such an effective option for both indoor and outdoor dust control.
With some types of dust, particularly chemical dust, adding water in large volumes creates a very real environmental problem. Runoff from the site that contains the dust can make its way to waterways or even to drinking water supplies. This results in fines and significant branding damage to the company.
By using a fine mist in dust suppression systems, there is no excess water. In fact, the dust and micron sized water droplets simply fall back to the ground with the additional humidity, preventing the dust from continuing to cycle through the air.
