Supercritical water (SCW) systems and methods using the properties of
supercritical water to allow a raw water stream including water and a
contaminant to be purified. A supercritical water oxidation (SCWO), water
purifier may generally include water and oxidizer (such as oxygen in air)
pumping and mixing apparatus, a supercritical water reactor, and a system
for separating the resultant purified water from other relatively
harmless outputs of the supercritical water reactor.
