As shown in Figure 1.1 , airborne particles may range in size from 1 nm (0.001 um) up to 1 mm or more. The larger particles, such as might come…

The critical factor in the creation and maintenance of dust-laden air or particle contaminated water is the nature of the particle, in terms of its size and its relative density.…

Contaminants, i.e. minor impurities, are normally present in all fluids, natural or processed. Where the level of contamination in the fluid is significant, i.e. too great for that fluid to…

At the time of writing, there is much concern being expressed about the global environment and human influences upon it. Whether it is to do with climate change and its…
