Seed-specific suppression

Equation (6) indicates that secondary nucleation is significantly affected by the crystal surface area A (m2/l). The nucleation process is usually viewed as a process where copious amounts of fines are produced, resulting in a corresponding increase in the specific crystal surface area (m2/g) and crystal surface areaA olume of the crystallizer content (m /l). Results obtained in this study concur with this nucleation view. However, Brown (9) reported that nucleation can be suppressed at high crystal surface areas ( 20 m2/l). Brown s observation was not evident in this study though the seed density of 200 g/litre used in this study had a surface area of 25 m2/l. The lower dependence of second nucleation on supersaturation or concentration driving force, AC, in comparison to crystal surface area. A, is obvious from equation (6).

There are, of course, always specific exceptions to this, for example, near new construction sites or by unpaved roads. But, in general, dust is not a significant problem. Mother nature ensures this by casting her seeds on the fertile soil and quickly turning any unused open space into a mass of overgrown vegetation very quiddy, thereby suppressing the dust in the most natural way.
