ABSTRACT:
A method of continuous precipitation of insoluble solids formed by the reaction of a liquid solution and a reactant by hydrodynamic agitation of the solution and the reactant in a continuous hydrodynamic precipitation apparatus. The apparatus comprises vertically standing elongated tank means; liquid level control means for maintaining tank liquid at a predetermined level in the tank means; hydrodynamic agitator means in the tank means for receiving and agitating the solution, the reactant and recirculated tank liquid; conduit means for supplying predetermined quantities of solution and reactant to the agitator means; pressure pump means for recirculating at least a portion of the liquid under pressure from the bottom portion of the tank means to the hydrodynamic agitator means; whereby the solution, the reactant and the recirculated tank liquid are thoroughly mixed by the hydrodynamic agitator means; and means for removing at least a portion of the precipitated solids from the bottom portion of the tank means.
