PRECIPITATION APPARATUS AND METHOD

摘要

Apparatus and method for on-line precipitation comprising a flow line (1,4,8) including a vortex mixer (5) for combining and mixing reagent flows. The admixed reagent flows are pulsed through an array (11) of vortex cells (12) to cause developement and growth of precipitate as the pulsed flow swirls through the array of cells with constantly reversing rotational direction. Precipitate in the flow from the array (11) can be separated in a hydrocyclone (14) and overflow from the hydrocyclone can be recycled.
