Report from S&T Project 7120: Measuring sparingly-soluble, aqueous salt crystallization kinetics using CSTRs-in-series: methodology development and CaCO3 studies

We present a methodology and results for measuring crystallization kinetics of sparingly-soluble salt mixtures typical of reject/concentrate streams from membrane-based, inland water supply processes. More usable water can be recovered (and lower disposal costs incurred) from these concentrate streams through efficient crystallization. In this work, we present a steady state, continuous stirred tank reactors (CSTRs)-in-series approach to study crystallization kinetics of a model solution mixture that is supersaturated in CaCO3. We have used pH, conductivity and turbidity changes in the system to monitor crystallization. We examined how mixing energy dissipation affects the induction times for crystallization.
