A model describing the role played by agglomeration in the growth of precipitates of sparingly soluble salts is presented. The model predicts that the mean size of the precipitate should increase with the agglomeration and unit particle generation rates, and that the resulting size distributions may be log normal. These findings qualitatively confirm previous experimental results. The model also shows that the precipitate size characteristics can be described in terms of a single parameter, a dimensionless drawdown time.
