1. A method for the separation of precipitates and other solids from a fluid comprising the steps of:

  • (a) introducing a pressurized feed material including water, organics, inorganics, and oxygen into a super zone of a pressurized vessel comprised of said supercritical temperature super zone and a lower temperature sub zone thereby forming a supercritical temperature fluid phase;

    (b) providing a liquid phase in the sub zone of the vessel;

    (c) allowing the supercritical temperature fluid phase to oxidize under supercritical temperature conditions in the super zone and to form an oxidized super fluid phase and precipitates therein;

    (d) transferring the precipitates and other solids from the oxidized supercritical temperature fluid phase in the super zone to the liquid phase provided in the sub zone, to produce a solution or slurry;

    (e) removing the oxidized super fluid phase from the super zone of the vessel; and

    (f) removing the solution or slurry from the sub zone of the vessel.
