Abstract
Apparatus for the on-line treatment of chemical reagents, including a flow line for a reagent flow, a vortex mixer in the flow line for combining and mixing the reagent flow with at least one further reagent flow, a pulser in the flow line for causing the pulsing of the mixed flow from the vortex mixer, and a vessel having an array of vortex cells for receiving the pulsing mixed flow to cause development and growth of precipitate under narrow residence time distribution conditions. Flow lines mix a flow of reagents to initiate precipitation. The pulser pulses the admixed reagents and causes the pulsing mixed flow to swirl with a constantly reversing rotational flow to achieve development and growth of precipitate.
