ABSTRACT:
A system is provided for treating spent geothermal brine to remove silica. The process includes introducing the brine into the reaction zone of a reactor-clarifier and allowing the brine to flow therefrom into the clarification zone of the reactor-clarifier. In the clarification zone, particles settle from the brine and are urged to the center of the tank beneath the reaction zone, and the settled particles are drawn upwardly into the reaction zone by an impeller. The particles mix with the brine in the reaction zone to form a substantially uniform distribution therein to provide nuclei for silica precipitation from the brine. A stream of sludge is removed from the bottom of the reactor-clarifier and disposed of.
