Dust fallout monitoring is a legal requirement under National Environmental Management Act, 1998. The act refers to the fact that the gazette must be used to set the standards. [Section 9(1)]. The gazettes are published with subsequent gazettes providing amendments to the standards.
If the dust levels measured are above the specified limits then engineering solutions need to be implemented to decrease the fall-out dust levels.
There are many factors that effect fall-out dust namely:
The challenge, once dust problems are detected, is to engineer them away.
Generally finer suspended dust (Greater than 0µm and less than 10µm) will remain airborne almost indefinitely due to the dynamic nature of the air currents and thermal activities on any given day, even if there is no wind at all. Particulate larger than this range will settle on a very still day and this material can be collected.
The unit that we use to capture this dust is the DustWatch, designed and patented in South Africa by Gerry Kuhn Environmental .
We offer the full service package or parts of the package as the client requires. We will also assist in getting existing fall-out monitoring systems up and running again. Obviously the full package allows the client to sit back and receive a report every month regarding their fall-out dust.
