ADVANTAGES OF ESTIMATING SETTLING RATES OF FINE PARTICLES WITH NOMOGRAPHS

The reliable calculation and estimation of the settling rates of parti cles from theoretical or empirical equations is highly sensitive to th e accurate description of their morphology and other relevant bulk pro perties. The aim of this article is to contribute to the 'systematizat ion' and link-up of concepts which are frequently unclear in the liter ature, showing the advantages of estimating settling rates of fine par ticles with nomographs. The recourse to 'nomography' seems to be justi fied in order to point out, in display form, the significance of the p arameters involved in the correlations most commonly available for the 'description of settleability of single particles and suspensions'.
