Abstract
A reconnaissance of the influence of hydrodynamics and supersaturation ratio on agglomeration of aluminum hydroxide was made. In this experimental study two important observations were made: the agglomeration rate constant is directly proportional to the growth rate, and can be related to the power input in the reactor system. These observations resulted in an empirical relation for the agglomeration rate constant as a function of the power input and the growth rate that has been validated against batch agglomeration experiments with three different type of impellers (Rushton, pitched blade, and flat blade) and with initial supersaturation ratios in the range [1.3, 1.8].
